SLBrook Posted January 17, 2011 Share Posted January 17, 2011 I have a 2006 F-250 that has these DTC's p0470, p0611, p2138, p2139, p0069, p0239, p0299, p2104, p2140 and p2285. I cranked it up and it ran fine for about 20 min and then i was letting it idle and then it reved up to 2500RPMs by itself and then it starts skipping. The wrench and the check engine light came on and then i drove it for about 5 miles and then the accel pedal stropped working and i had to idle it back to the shop. Can anyone help me about this?

At least you got rid of some of the O2 sensor codes The P0611 is still straight forward. This isn,t going to give you an unintended acceleration, though. Like I indicated in my reply to the deleted thread, the TSB (10-12-06) will help you diag this code. If it is retail, forget the PMI - it rarely shows any improvement and the thing will likely come back to haunt you if you don't replace the FICM P2104 is just telling you that the PCM has limited the throttle response - most likely due to the three APP codes you have. When you are testng the APP, remember that it has a redundant V_REF (two V_REF supplies at the sensor) that is interconnected inside the sensor. This can add to the confusion if you shortcut any circuit testing. I've seen wire chaffes give APP problems. And an APP concern could give unintended acceleration - if only briefly. Your APP problem may be affecting V_REF for other sensors so I'd concentrate on the obvious concern before I got carried away with the MAP, ABP and ICP. You might consider clearing codes and see what comes back. Quote Link to comment Share on other sites More sharing options...
