Light came on a few days ago. 2000 exc with 7.3 diesel the mileage report said 155000. Took it to Autozone a hour ago and these are the codes: P0683, P0676 and P1670.
View 14 RepliesSo i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.
View 14 RepliesTruck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?
View 7 RepliesThe SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.
Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.
My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?
I have a 2001 F350 and my service engine soon light came on. For a while it went on and off and every time it came on the engine ran rough and I lost some power. I pulled the valve covers and checked the UCVH and everything was fine that I can tell I even made the shims out of quarters and put them in. After putting it all back together its still doing the same thing.
View 1 RepliesI was on the way back from the weekend trip and got a service engine soon light. I didn't notice any lack of power, rough idle or hard starting cold or hot. So we pushed on home. I checked the codes and it is the P1211.
Doing some research it seems the ICP is not as expected so I hooked up my phone with the Torque app and the IPR and ICP seem to be close to normal at idle and running. I din't see any high IPR %.
At idle the IPR was around 15.5 cold and 10.1 after a short run to the store and back when it warmed up a bit. ICP was around 690-720 cold and 470-490 when i got back.
Does that seem like normal readings? I cleared the codes and the CEL comes back on right away after starting the truck. I do have a TS performance chip that I will take out and see if that could be causing any problems. What else should I be looking into?
On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.
View 2 RepliesSo about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?
I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.
my 2003 f-250 4x4 6.0 engine service light stays on all the time (for about 2 weeks now) it has 33,323 miles on it. it is running fine-no problems yet. no codes are showing up on a diagnostic test. What is going on?
View 10 RepliesI have a 2000 f350 7.3 got a check engine light that turns off when rpms go up and a slow start. My mechanic said that there were no codes being blown, what is going on?
View 11 RepliesThe Service Engine Soon light has come on on my 2000 F-150 with a 4.6L when I was driving home in the rain. It has about 120,000 miles on it now. What are some of the main reasons why this comes on? Oxygen Sensors?
View 14 RepliesI have a 2000 f150 with 198,000 miles. The lite on the dash came on, "service engine soon" , I had the codes read and they said the coils are going bad.
View 2 RepliesA couple of weeks ago I got a service engine soon light and it turns out that the egr cooler core was bad. I had it replaced this week under warranty but now this has me thinking that maybe in the long run I would be better off to tune the truck. I had not even considered it until now, but this is a truck that I plan on keeping and I think that all of this emissions crap is shortening the life expectancy of the truck, at least without dumping money into it on a regular basis. Would this have been caused by anything that I have done? Am I not driving the truck hard enough maybe?
View 2 RepliesRemoved and resealed HPOP and fuel bowl. Now she won't start. Ran fine before pump & bowl was serviced. I had leakage that I wanted to clear up. I have made no less than eight 15-20 sec start attempts with out even a cough. Reservoir is full, fuel in bowl and over 140 RPM when cranking.
AE info:
IPC duty cycle - rises to over 60% during cranking
IPC voltage - .18 all the time
IPC psi - 0 all the time
I did verify I placed the ball between the pump face and the "non serviceable" pin. I did leave out the spring and check valve seat from one of the output connectors. That has been corrected.
Cooler weather has arrived and my 2000 f250 won't start. Wait to start light is coming on, no power passing through the two relays on top of the engine. Are both of these for glowplugs? My 97 only had one. How do I diagnose relays on this truck? If you cross out the two relays truck fires right off so I know the glowplugs themselves are good.
View 7 RepliesSo 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.
View 5 Replies Auto trans. The Overdrive light flashes on the Selector lever. Never stops.I put tape over it because it is annoying. Especially at night. It goes into overdrive no problem.
A Couple of times it did not flash and was stuck in first till I manually shifted. Then the light started flashing again and works normal. What now......RPM Sensor?
My 2002 7.3 engine makes a slow tap sound...

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.
