Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 - High Idle / Over Drive Light Started Blinking
Jul 30, 2017
OK, truck is 2000 F350. I am heading on a 2000 mile roadtrip to Yellowstone for my wife's 40th birthday in two days. What was our rock of a vehicle is now causing me severe anxiety.
Over the last few days the truck has been difficult to start - almost stops turning over as if the batteries were low. So I ignored it because if I plug it in, it starts fine and if I drive it and it gets hot - it starts fine.
Tonight while driving - I noticed a high idle and then it went to normal - I thought it was weird and a few miles later at a stop sign it struggled at idle, sort of loping but not romping very high and the over drive light started blinking. When I got home when I went from drive to neutral it goes to high idle and then the overdrive light blinks. The first time it blinked it went off when I pressed the OD button - but now it continues to blink.
Would low batteries be the root cause of this? I will continue my search for blinking OD light but I thought I would get this in the queue in case this is bigger than I can handle. I have 48 hours to resolve this issue - leaving Wednesday early morning.

Well, long story is that I starting have problems with my 2000 F350 Dually 7.3 PSD about 6 months ago ( ~10K miles ago ). I have sunk almost 5K$ in mechanics and the problem is still present.
By troubleshoot, I do not mean try this, try this, as that has been what is happening. I mean making test measurements and diagnostics. I am fairly mechanically inclined, but I am no mechanic. Looking for primers on how the 7.3 PSD works.
Symptoms: After the truck sits 12 to 14 hours, it starts and idles fine ( ~ 700 RPM on the 'Dash Tach' ) just as it has always done. During the first 5 miles of driving it, the SES light comes on and it sputters, stalls, and vibrates as if a couple of the injectors are not firing. It then clears up and the SES light goes out, except that it idles at about 1200 RPM ( 'Dash Tach' ).
It runs fine like this the rest of the day, If I shut it down it will start right up and run fine, but it has the high idles. Only if it is shut down longer than 12 to 16 hours do the symptoms, other than the high idle, reappear. The high idle is constant. Also mpg have fallen ( 13 opposed to 16 ).
It does not seem to be related to ambient temperature, or the amount of warm-up idle. I have idled it for three hours on startup and it is fine, until I drive the first 5 miles or so.
Now, I have had three mechanics work on it and they have replaced: the ICP sensor ( 3 times ), the Fuel filter ( twice ), drained, flushed and refilled the HPOP, replaced both sides of the valve cover wiring harness, put in a new IDM, fuel heater, CPS sensor ( 3 times ), fuel pump in fuel tank, EBPV ( not sure what this is ), and the last straw was saying the injectors needed to be replaced ( or at least the O-rings, but while we are in there you might as well ... ).
I bought a cheap code reader and it says: P1316 & P1211. I believe these are the same codes since day 1.

So my OD light started blinking on the way to work today. The fact that my truck dropped out of cruise control and then started downshifting out of OD on the freeway and back into OD started this ordeal. A quick scan of the dash made it easy to notice the OD light strobe, especially in the dark.
I've read some posts in the past in the event it happened to me since my truck is far from new. I had it in the back of my mind that I would attack the VSS sensor with some contact cleaner then replace if that didn't fix the problem. Doing a search revealed a far greater spectrum of culprits. In addition to the VSS potential I have read about transmission handles, chafed wiring in the steering column, and even the transmission itself. Instead of re-inventing the wheel I'm looking for those that have more knowledge on this issue than I do. Here are my symptoms:
1. Drove 5 miles from my house to the freeway with no issues.
2. Shortly after getting on the freeway I set my cruise control at 65mph.
3. Shortly after that my cruise control 'dropped out' and the truck started to slow down (obviously).
4. When I got back up to speed the cruise would not work which is when the out of OD and right back into OD started. It did that all the way to work (it would go out of OD and back in every couple of minutes or so).
5. Transmission hunted on surface streets too (25mph).
6. Turned the truck off, waited a couple of minutes, then started it back up. OD light is off and truck drives fine.
A couple of things to note. This is the first time anything like this has ever happened with the truck. Also, I have Torque Pro and my instantaneous MPG meter was at 0.0 the entire time this was happening. When I turned the truck off and back on, the MPG was displaying again normally. This is what made me thing something with the VSS connector.
I decided to search the issue and confirm my suspicions then found out that this could be a lot more difficult to pinpoint. Since it cleared up when I cycled the key I am ruling out a transmission issue (for now).
I plan on cleaning the VSS connector (that's the plug on top of the rear axle right?) and then pulling the cover off the steering column to see if I can see any chafed wires. Is there anything else to check out while I'm rooting around? I will add that my transmission handle has always been loose (I think the original owner used to drive with his right hand resting on the handle).

My 00 F350 has never started when the temps were below 25 unless it was plugged in. This year is no different, but now it won't start when it's plugged in. It just turned 200K and I know things have to be checked, but I don't like doing them in the winter so I was hoping to make it through this winter and fix things. I needed to use the truck the other day so I plugged it in before I went to bed, It wouldn't start, so I got looking, crawled under the truck and the block around the heater was cold, checked the plug with an ohm meter and it showed that there was an open, so I checked the cord, sure enough there's a splice in it, with a broken wire, so I fix all three splices, check it again and it's still open, under the truck again, and find another splice at the end of the factory wire loom with a broke wire, got them replaced, got a good reading with the meter, and now I'm back in business, Plugged it in for a couple of hours, hit the key and it fired like it was new. Well not that good but it did start.

While headed back to town my 2000 f350 7.3 with 444,650 miles (I'm original owner) and have performed maintenance and repairs since mile 3. Truck started to loose power and eventually stalled, was able to restart several times to limp home 7 miles in one hell of a snow storm. Very confused, replaced cam position sensor ( keep one in jockey box ) replaced fuel filter truck starts then stalls out. Don't know if a bad HPOP would allow start up at all. Fuel pump???

I was out with the F350, drw, automatic, 7.3, 4 x 4, yesterday about 30 miles from home base. The transmission started pumping fluid out the front like I have never seen before. I am not talking a drip, I am talking a stream, a big one..... almost like pouring coffee from a coffee pot. I noticed it when I was backing into unload and was leaving an oil trail, a quite obvious one.
We took off the tc cover as it was coming off that to find a dry tc and flywheel, but fluid running out off the case. This is the second time this trans left me high and dry in 165k miles. The first time was a stripped tc/ input shaft. We repaired the transmission then but I don't think we replaced much besides being sure no debris went though everything, fixed what was broken. That was about 25,000 miles ago.

I have a 2000 F350 4x4 CC 7.3L 323,000 miles auto trans. I have removed my tuner just to make sure that it was not the issue. The truck will run fine then all of a sudden the idle will rise then fall or shudder or go up and down and sometimes it will just Die but it always restarts. No trouble lights at all. I am not sure what is causing the issue?

So here's the deal: My 2000 F250 has began to have the overdrive light blink when I am traveling at low speeds <40mph and it is accompanied by strange shifting (lower gear for a longer period of time). As soon as I get up to highway speeds the blinking stops and goes back to normal operation. But as soon as I go back to low speeds it happens again. When I put the truck in to park when it has the light blinking it revs it self to about 1200rpms then goes back to normal idle. This truck has 228k miles and is on the original transmission.

I have a 2000 f250 with the 7.3 and 181,000 miles on it, recently got stuck in the snow (in 2wd because i forgot to lock the hubs) and the rear wheels did alot of spinning. Now i randomly have the OD light start to blink, sometimes its a half a blink, sometimes it'll stay on for a few seconds, itll do it randomly while crusing down the road at a constant speed, also noticed my rpms fluctuate a tad at idle.

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

I have a 2000 Ford F350 7.3 with the auto and 262,000 miles on it. As far as I know everything is stock on this truck. It has been a great truck but lately its been making a strange noise. It almost sounds like an exhaust rattle or vibration but it is intermittent. Its not really loud it can be heard best in the cab at idle. I've looked all over on the truck and haven't found anything. I can't pinpoint where it is coming from. I tried starting the truck with the serpentine belt off no change.
I took the inspection plate off the bell housing and couldn't see any cracks the torque converter bolts appear tight, and the starter is not engaged while running. I've read a few forums on the torque converter going bad. It looks to me like its more the 99 trucks that had trouble with that. Did the torque converter issue carry over to the 2000's? Would a torque converter/transmission problem be intermittent?

Was driving my truck normal, got to a stop and the truck staring to idle high and like stuck on third gear and also the tow light (over drive) started to flashing Is like the truck put it self on safe mod. Drove it back home but couldn't do more than 55 miles n hour so I didn't hurt the trans.

I bought this truck with a stock automatic transmission and 260k miles back in October expecting the transmission to be the first thing to go. Recently I had a transmission code, OD OFF light flashing, for the bad speed sensor which i got replaced. Then the OD OFF light started flashing after some hard driving when I would put into neutral or park so I took it back to the mechanic, Hanahan Truck and Auto in Sc. They looked into it and there wasn't any different code in the system but they noticed when you lay into it driving it slips some between 2nd and 3rd gears so that could cause the computer to put in a code.
They said usually a rebuild runs from $2k-2.5k and they also recommended a Jasper reman for roughly $2.8k which comes with a 100k mile 3yr warranty. So I figure replacing the transmission is probably the way to go. Any recommendations for a replacement. I've heard ATS and Sun Coast are decent options that I could build one. I'm looking to stay close to $3k. My truck is a 2000 F250 lariat 4x4 with 268k miles. I'm installing an S&B intake, 4" MBRP exhaust, and DP-Tuner's F6 chip when I get the transmission work done.

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

My new to me 99 f350 has a great a/c but it only blows on high. Am I looking at a blower motor, resistor, or the fan switch? I'm grateful that it does blow on high being in SE TX and SW LA. If it didn't I couldn't ride in the old girl. A black truck with no a/c is not happening this time of year....

I will start off with saying I am posting this for my dad. His truck is a 1999 F350 crew cab DRW 4x4 auto 7.3 with about 189K miles on it. He is leaving wednesday on a cross country road trip pulling a 40FT 5th wheel (no idea the weight but the thing is huge). He has glowshift gauges installed, one of which is the trans temp gauge. I believe the transmissions on these are 4R100, but I am not positive about that, but I'm sure many people here will know. He just told me that he had the mechanic he goes to replace the pan gasket on the transmission because it leaked quite a bit, just as a precaution. He also had them replace the brake booster as it was leaking inside by the brake pedal. When he got it back, he said he was driving it, and the temperature started going up to I believe 220 degrees not pulling anything. He said since he installed the gauges it has been between 180-190, and it jumped to 220.
What this could be. I have read that the TFT sensor can cause this issue, but it would throw a code and possibly go into limp mode. He has no check engine light and it was driving just fine. So the temperature is just all of a sudden high. Fluid level is fine, was checked after about an hour of driving, is red, and doesn't smell bad. I am suspecting the temperature isn't actually hotter, so there is another issue. It's only a big deal now because in a few days he will be dragging a huge 5th wheel behind him.
Last year, we towed some pile of crap 5th wheel down to our city for somebody with his truck, and we had to pull over halfway back because it started to smell like something burning. We think it was the trailer, as the brakes were questionable on them. When we got it to the people we were delivering it to, when we left, it wouldn't shift passed 2nd gear. He only lived a few miles from there, so he drove it home, parked it, then went out the next day and it was fine. He had the fluid flushed later and that issue hasn't come back since. No other work was performed on it since the pan gasket a few days ago. I am not sure if they are related being a year apart, but figured I'd mention it anyways.

I drove the truck to work. It was fine. I start it up at quitting time and let it idle for a minute. When I pulled out of the parking lot and the od light started blinking. After about 8 miles I stopped at a red light. When the light turn green and I drove off the speedometer is working again. The od light flashed for another mile or 2 then stopped.

Funny shifts and OD light blinking. Have p0741 and p0743 codes. Checked wiring and no visible damage. Checked continuity on the purple-yellow TC wire from connector under hood and at Trans and their is none.?? Also will I hurt the Trans driving this way if the temp stays in check?

I have a 2002 F350 4wd with the 7.3. I was driving the truck and all of a sudden it was running like crap. the engine light was on. after a minute or so the engine light goes off and the truck is running fine. then again starts running like crap. I am close to the house so I limp it home. runs like crap.... will barley climb small hills. engine light is on. get home turn it off... next day... starts up and runs great for 10 - 15 min. engine light comes back on... runs like crap.... my neighbor says "It's the crank position sensor" I replace it.... runs great for a month.... now it's doing the same thing......

Just happened today right after I bought diesel. thought it may be water in fuel but after researching wondering if it is injector, etc. It starts every time knocks real bad sometimes for a minute, but clears up to idle ok. During idle no smoke, slightest acceleration however produces white smoke harder I accelerate more it plumes and it smells like diesel in the air.
Cannot get past 15 or so mph till switching into 2nd gear then 25mph max. Had to drive 4 miles like this I can say it cleared up and drove 1/2 mile until I had to stop at a traffic light then going from idle to acceleration again ran bad rest of way home another 2 miles.
A few years ago I did have a rough idle and accel. similar and it ended up being the broke pick-up/sending unit in tank (but of course that was when you get to around 1/4 tank of fuel and didn't run bad above that much fuel in tank), plus there was almost or more than a gallon of water in tank. I have done the mod for the fuel pickup with hoses, filter canister, etc. but wondered at first today if I had gotten bad gas or water in the tank again. Not sure how that much water got in the tank to begin with but that was bout 5 or 6 years ago.
Truck has over 200k miles and Ive had it for 11 years. In the morning will check the ICP sensor by unplugging look at fuel filter bowl, etc. A question I have is: Is water heavier than diesel, would it run thru my line first? thinking diesel is heavier than gas because of oil content....

Speedometer not working and O/D light blinks, I have a 450 and a 250, 99 and 2000. On 450 this is an intermiting problem. Stop truck turn ignition off, restart and it all works now. Just started on my 250 and stopping and turning ignition off cures the problems for a few seconds, after i get moving the speedometer doesnt work and then light starts blinking again O/D light.
