The P2167 code indicates that the engine control module has detected an incorrect voltage signal from the Throttle Pedal Position (APP) Sensor E when the pedal is fully depressed. This suggests the sensor is not reaching its expected maximum voltage threshold, signaling a performance failure at the maximum stop position.
Internal wear or failure of the potentiometer within the pedal assembly prevents the signal from reaching the maximum voltage limit.
Frayed, shorted, or broken wires between the pedal sensor and the PCM can disrupt the voltage signal.
Moisture or debris in the sensor connector pins can increase resistance, preventing the correct voltage from being reported.
A failure in the PCM's signal processing circuit for the APP sensor, though this is rare compared to sensor or wiring failures.
The vehicle is likely drivable, but it may be in a reduced power mode (limp mode) for safety, which significantly limits acceleration.
No. P2167 refers specifically to the sensor at the pedal assembly, not the electronic throttle body actuator.
No. It is very rare for the PCM to be the cause of P2167; the issue is almost always found in the sensor itself or the connecting wiring.
