Can somebody post up the diagnostic flow chart for p0748? My burb has been setting for a few months, get in it to drive and all is well, get it up to temp, flog it a few times, bam limp mode hits then the light. Cleared it and it was fine for a few minutes, then it would do it after it
was in 2nd for 5+ seconds, and now it pops as soon as I start it up. I haven't checked power at the tcm, but I have 13.8 at the fuse, and p0748 is the only code. I know it's an electrical code for the a trim solenoid, just was hoping to get a flow chart to go by.
