6.0L very confusing problems

SLBrook · January 16, 2011

I have a 2006 F-250 that has these DTC's p0470, p0611, p0138, p0139, 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?

That's quite a mish mosh of codes you got there.. That P0138 and P0139 are a tad disconcerting... they indicate there is a problem with the downstream O2 sensor... What kind of scan tool are you using?

For you engine revving on it's own, look to the P2104 and P2140 first as possible concerns. Be careful here - these two codes take two different routes in the PC/ED but converge where they tell you to replace the PCM... "Be afwaid... be vewy afwaid...". You will likely need to clear codes and see what comes back first.

P0611 is pretty straightforward. Look at TSB 10-12-06 for some guidance. If the truck is off warranty don't be overly concerned with the PMI stuff.

For your P2285, follow the PC/ED... We have seen, in the past, P0069 and P0470 set durinbg cold weather... check to see if the truck is at the latest cal...
