P2125 Toyota Code - Throttle Pedal Position Sensor/Switch 'E' Circuit
Quick Answer
The Accelerator Pedal Position (APP) sensor is built into the accelerator pedal sensor assembly and has 2 sensor circuits: VPA (main) and VPA2 (sub). Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position Sensor harness is open or shorted, Accelerator Pedal Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2125 Toyota Description
The ECM monitors the actual accelerator pedal opening angle (throttle valve opening angle) through the signals from VPA and VPA2 and controls the throttle actuator according to these signals.
When either the output voltage of VPA or VPA2 deviates from the standard range, or the difference between the output voltages of the 2 sensor circuits is more than the threshold, the ECM determines that there is a malfunction in the accelerator pedal position sensor. The ECM then illuminates the MIL and stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P2125 Toyota?
- Faulty Accelerator Pedal Position (APP) Sensor
- Accelerator Pedal Position Sensor harness is open or shorted
- Accelerator Pedal Position Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
