I am trying to find out how many o2 sensors are suppose to be on my 2003 excursion? I am getting two codes on my OBD reader, an "o2" and an "o2 heater" code flashing...... I have replaced both the o2 sensors i found, both were at the exhaust manifolds.
View 14 Replies2000 F150 V6 auto just bought it 140k. Check engine light on.. Code reader wont come on? has 2 lighter sockets in dash one on the left works right one dont? I hear one is inline with the code port? Checked 1 fuse #110? looked good...I don't have a manual so I"m lost.. or there are more fuses?
Also the speedo mileage sometimes will go blank? at start up then come back on ?? seems to be working even when blank? First I need to get the code reader port to put out..so i can see the codes....
Truck had a rich on bank 2 code about a month ago, I cleared it and the service engine light stayed off for quite some time.
Last friday on the way home from work the truck started shaking badly right from idle, and at one point on the freeway the service engine started flashing. I couldn't pull over as I was on a bridge but once I dropped my speed the light stayed on but the flashing stopped.
I went to plug the truck in today and first shot it didn't communicate with the code reader at all, I talked to someone who told me that the cigerette lighter fuse is also the OBD port fuse, I pulled a fuse from somewhere else and plugged the reader in again. This time it started communicating with the truck but didn't display any codes while all the while the truck is miss firing and the service engine light is lit up on the dash.
One other weird thing: The fuse had an LED indicator to show that it is blown, when I push the cig lighter in the led gets a hell of a lot brighter, if there is always power drawn through the circuit shouldn't the LED be constantly bright all the time? I'm wondering if there is a short somewhere. Where to look next??
On the way home tonight, the O/D light started flashing. I happened to have the Bluetooth OBD adapter with me, so I plugged it in and opened Torque. It comes up with a "pending" code of P0743. After a little bit, the light quit flashing so we drove the last mile home. The O/D light began flashing again the last couple hundred feet before our driveway. There didn't seem to be any loss of power or anything like that the whole time.
After we got the kids to bed I went back out to check the fluid level. (It had cooled some, so I let it run a bit before I checked it - the light wasn't flashing this time.) The level is at the second dot, right below the crosshatch. It's almost transparent, but I don't know when it was last flushed (if ever). From what I've seen on here, I'm guessing this is an electrical short somewhere?
2003 Ford excursion 7.3L powerstroke eddie bauer edition, vehicle wont start unless the block heater has been plugged in and the block is good and hot. This is its only symptom. It is throwing the following codes when i try to start it. Mind you it is 70 degrees so it shouldnt have to be plugged in to start
P0470 : Exhaust Pressure Sensor. P1000 : OBD System readiness test not complete
Me and the wife got in the ole '97 1.8. After may be 5 mins or so, I noticed the CEL was on.
I've only ever seen the CEL light on once, and it was b/c the gas cap was loose.
The car ran fine, nothing out of the ordinary. After getting home, I plugged in the dusty OBD reader thingy and it spit out a code, I can't remember. P401 or something like that. EGR emission low?
It appeared that my EGR valve is all cruddy with carbon deposits. So Is removal/cleaning terribly difficult? I'm thinking some carb cleaner and maybe a scraper would do the trick.
I have a 2003 Ex with the 7.3. There is a leak in the rear coolant line just in front of the rear right tire. Is there any way to bypass the rear heater under the hood?
View 1 RepliesI have a 2004 chevy silverado 1500 ext cab with a 5.3 L 4X4 , I tried to plug in a code reader and I'm not getting any readings . The reader is working , My question is can this be fixed by me or do I have to take my truck into the dealer?
View 7 RepliesOk, did a quick search, found nothing. Is there a way to get CEL codes without a reader on '01 F150? I know the way on 80's stuff, is there on newer stuff?
View 2 RepliesI have an '03 w/ the 7.3L. Today the tranny stopped shifting up out of 2nd. And the O/D light flashes. There are no other MIL lights on. I have do some searching here and some say the VSS (Variable Speed Sensor) is bad, some say there is a connector on the passenger side that needs cleaning, and some say there is a solenoid just inside of the tranny bottom that needs replacing. So, what shall I do?
View 4 RepliesI am told I am possibly having some engine misfires and I need to get my error codes read. The problem is I don't want to drive the car to an auto parts store to get read because the engine is really rough and bumpy. So what kind of code reader to get, OBD I, OBD II, CAN..etc??? I have a 2000 Buick Park Ave. I have a mechanic coming over tomorrow, and it seems he doesn't have a code reader off hand, so I gotta pick one up...
View 4 RepliesI've got a 2003 Ford Explorer The transmission O/D light is flashing, and the check engine light came on. I'm getting and Code of P0775 Pres. Ctrl Solenoid B Circuit Malfunction. Also it shifts rough between gears, the rpms ramp up to much before it shifts. What the problem is, and how to fix it?
View 13 RepliesIt is a 1997 Ford f150 5.4 4x4 extended cab 175k miles. Took a 600 mile trip, first 300 no problems, then the "od" light began flashing, the truck shifted fine so I kept going, drove for about a 100 miles then stopped for fuel and read the code, (p1728) cleared the code and drove another 200 miles, no light no problem. The whole time there was no drivability issues. Yesterday I drove all over town, stop and go traffic, locking the TC and it would also unlock, no problems all day, drivability was fine. What to do?
1. Just keep driving it?
2. Does changing fluid fix this problem?
3. Rebuild the trans, because this was just the first notice.
4. Sell it quick no light and drives fine.?
To start I was driving to work tonight and noticed the o/d "off" light flashing. it shifted hard one time then felt normal the rest of the way to work. At red lights the o/d light world turn off and about 3 minutes later it would flash again. When I got to work, I checked my code reader which gave me the p0705. I have searched around the net for about an hour and one thing i am seeing is that the fluid is "hot" or that there isn't enough. i have checked it and it looks slightly low like right above the add indication.
The only sound I here from under the truck is a rattle when in drive and at idle, but once I give it some gas it goes away. On they way home that night the o/d light was still flashing but it drove fine just at higher rpm, it down shifted hard one time but there were no other issues. I checked the fuses and they are all good.
I have a 2003 Excursion 7.3 2WD Limited and all of the sudden experienced a number of issues all at once.
1. Turn signals stopped flashing (hazards still flash)
2. Lost Rear back up sensors
3. Lost overhead trip computer
4. Lost Rear A/C - switch does nothing
5. Front A/C now only blows through the defroster vent
I've checked all the fuses and cant find any bad ones.
I replaced the multi-switch flasher and turn signals still dont work - only hazards.
Just started the truck after not running for a few weeks and drove around fine. Looked down and suddenly a CEL was indicated. Checked it with my Edge Evolution diagnostic mode and Code P0161 came up 2nd bank downstream heater circuit fault. I've also have an exhaust leak in the right passenger side exhaust manifold for about the last year. I've been waiting to install my newer 03' used engine when time and funds permit.
View 3 RepliesI am trying to make sense of a P0741 code accompanied by a flashing OD light.
The truck is a 2002 (12/01) build date) F250, 7.3,4x4, Auto, with 245,000 miles on it. The truck seems to shift fine but around 40/45 it feels like the TC does not lock, followed by the flashing OD light.
The transmission was serviced 500 miles ago but the OD light flash was intermittent until last week, now its been constant. I want to take care of it before I do any damage.
Air Intake Heater Plug Code Eliminator P0541
In conjunction with the AIH Delete Plug??
So here it is, I have a 2002 F 250 CCSB, 7.3, 180k, 4R100 Auto (Build date 06/02 so no mechanical diode correct?), 4x4, 4 inch exhaust, Riffraff 6637 Blue filter, with edge evolution (run in STOCK ONLY, just using it for gauges) that has recently thrown the P0781 code, and flashing the OD button. The interesting thing is I haven't noticed any hard shifts from 1-2 or any gear change for that matter. Fluid was changed less than 2k miles ago, was nice and red.
I have read of others having to rev up to 2500 RPM and then let off of the throttle to shift. No such issues here. Drives the same as usual. The only issues I can think of would be a sticky shift solenoid, sticky shift valve, or intermediate one way clutch that can cause this problem, but as it is only a code and blinking OD light and no actual shifting problems I am at a loss?
I have a persistent issue with the OD off light flashing on my 2001 7.3L auto 4x4. Scanning it with AE I get the P1832 code. The truck runs and drives just fine. It shifts nice, goes into overdrive, locks up, etc. If it weren't for that blinking light I'd think it was all perfect. I've checked all the connections, replaced the range switch / neutral safety switch, replaced the VSS on the rear axle, checked all light bulbs and fuses. I've checked MOST of the relays in the truck.
I pulled the tranny drain plug and poured out a bit of fluid into a clean pan, it looks and smells good. AE also tells me that it's not communicating with the ABS system (although there's no persistent ABS warning light on the dash), the Airbag, the Overhead Trip Computer, the Parking Aid (which I don't have...), or the Enhanced Powertrain. The temperature on my overhead display is reading -40F which is clearly wrong.
I've looked for a comprehensive wiring diagram for the truck, but can't find one. I'm trying to figure out if there's a connector or module that these various functions go thru that might be the problem. Am I missing a ground somewhere? The frame was just powdercoated......am I not getting a good ground connection? In complete disclosure, I have torn this truck apart and re-assembled it out of several different trucks as outlined in this thread.

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.
