Car will be driving fine and suddenly dash shows "Reduced Engine Power" and will speed up gradually. So had my sister discontinue driving when I noticed the issues.

Hello,

Is the check engine light on? The TPS sensor on the throttle body and the pedal sensor control the reduced power issue. The code will help us track down the failure.

Cause

On some vehicles, the IP to body harness connector, which carries the APP signal to the ECM/PCM, is located in the left hand kick panel area and if the kick panel is not sealed properly, water enters and causes a short in the APP circuits setting a P2138 code.

Correction

Do Not replace the accelerator pedal assembly.

Locate the IP to body harness connector, which may be located in and around the left hand kick panel area. Check to see if there is a water leak into the area and repair as necessary.
