P2138 - How To?
'06 Colbalt LT.
Driving today, check engine light, reduced engine power and T/C turns off. Made it home, scan for codes - P2138. Got this about a month ago as well (along with P2128 ). Digging around online, seems like the likely culprits are accelerator pedal position sensor, loose wire someplace, or there are two TSBs I think, a leak in Pillar A that may leak on a connection, and checking the PCM build dates as some were faulty.
Any other posibilities that need to be considered? I've learned the PCM code is not suspect (had that checked out last time the code came up) and code popped today when it was sunny and 60, hasn't rained in 3 days and has been driven 90 miles prior to getting the code. Thinking I should have the APP sensor taken care of?
Is this a difficult replacement? Anyone have a how to or could give me a walk through?
