South Florida If you have an APP issue on a 2007-2011 GM truck ill look at it for free. It is part of a on going research project. Bring it to my shop for free diag and maybe repair.

GM is having issues with water shorting out the connectors between the ECM and the APP. If you already replaced the pedal and are still having issues To fix this you may need to replace the wires between the APP and the ECM.

"This condition may be caused by water intrusion into the instrument panel (IP) to body harness connector, which
carries the APP sensor signals to the ECM/PCM. This water intrusion results in a voltage difference between APP
Sensor 1 and APP Sensor 2 that exceeds a predetermined value for more than a calibrated period of time, setting P2138."

If you have a complain of a SES light and reduced engine power message as a result of any of the following APP Sensor DTCs: P2120, P2122, P2123, P2125, P2127, P2128, and/or P2138. This may be your problem.

Look for TSB #07-06-04-019F: INTERMITTENT MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATED, DTC P2138 WITH REDUCED ENGINE POWER (REPAIR INSTRUMENT PANEL (IP) TO BODY HARNESS CONNECTOR) You can google it.

I also recommend you file a complaint to NHTSA so they recall this dangerous problem. here is the link

The more reports the more likely it will get recalled and maybe you can get your money back.

I recommend reading my report on SUA
