Ford Repair Questions? Ask a Mechanic for Answers ASAP
HiCustomer Thank you for asking your question on JustAnswer.
You need to have the powertrain control module reprogrammed.There is a tsb out for this concern from Ford.No amount of replacing ego sensors will fix it.This is a dealer only procedure as they will be the only ones with the correct calibration files.Next time you get a code ask here first before replacing parts unnecessarily,might save you some $$$
Have a great weekend!
Ok thanks for the information> I will take it to ford and get a reprogram if that fixes it then. I will click accept so you get credit for this information. Thank you.
Ok had a buddy of mine who works for ford come over yesterday and flash PCM. Looked like that took care of problem but this afternoon check engine light came back on with the same codes again P0135,P0145,P0155,P0161. I have a data view of all the PIDs for the o2 sensors, I have ElmScan on my laptop thats how I got these PID's. Would you like me to send them to you so you can look over?
Ok, let me know what you find. Remember,if you are checking voltage with a meter,it is possible to read battery voltage but that does not reflect the circuits ability to carry current under load.Also here is the wiring diagram,notice at splice 100 circuit 361 branches off to the 4 sensors,If you are missing voltage I would suspect the problem to be on the sensor side of the splice.That splice should be in the harness coming off sensor 11.
Ok the grounds to the pcm are good. Went today and pulled this pcm its the closest could find.( EEC-V ML2-30C 7F02 F7DF-12A650-EE 67MH30CB18-AC). The number on the original is (EEC-V ML2-30C F7DF-12A65-DF
67MH30CB17-AE 43223-658). The one I pulled is from a 97 I noticed when pulling different ones the the first four digits of the code changed with the year of the car. Like F7DF the 7 was always a 1997 car if it was F6DF it was a 1996 or a F8DF it was a 98 year. So I'm not sure if this one will work maybe you can give some info before I install it I had a couple of people who said they just pulled them and installed them and the car was fine. One guy said since this was a 97 it did not look for a VIN of the car and should work. What do you think?
What I ment to say earlier was not vin number but pats. Ok let me make sure that I understand what your saying. With this pcm as long as no pats system it should start and run? I need to upload the software from my old pcm to the one I just got? Just to make sure it has all tsb updates and the same software? If thats the case I can get my buddy to do that. The taurus I got this pcm from was just like my sable in that the engine type, tire size etc are the same. A least the tires looked like they may had maybe 1000 miles on them, I should have gotten them also but did not need the wheels. The wrecked car is from a local ford dealer so the emisions system should be the same . The only difference is it was a sedan and I own a wagon.
