What do you need to know about the p2138 code?
Cost of diagnosing the P2138 code. P2138 is a diagnostic trouble code (DTC) for “Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is the p2138 throttle position sensor and switch?
P2138 Throttle/Pedal Pos Sensor/Switch D/E Voltage Correlation Trouble Code Fault Location Probable Cause P2138 Throttle position (TP) sensor/switch D/E Wiring, TP sensor/switch
When to use the p2138 malfunction indicator lamp?
If the two signal inputs vary by more than the acceptable programmed limit, for more than a certain period of time, a code P2138 will be stored and a malfunction indicator lamp (MIL) should be illuminated. In most cases, the PCM will also enter limp in mode. In this mode, engine acceleration will be severely limited if not disabled.
What is the p2138 code on a Pontiac Grand Prix?
Hi all, I have a 2007 Pontiac Grand Prix with sunroof which is throwing code P2138. This has been going on for nearly a year now. When driving in rain or very wet road conditions the Reduced Engine Power message will come on along with the check engine.

What does the p2138 Chevy app sensor mean?
P2138 Chevrolet Meaning. The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5-volt reference circuit and a low reference circuit for each of the sensors.
