Code P2123 2014 Toyota RAV4 Description
The P2123 diagnostic trouble code (DTC) for a 2014 Toyota RAV4 indicates a problem with the Throttle Pedal Position Sensor/Switch 'D' Circuit Input High. This means that the Engine Control Module (ECM) has detected a higher than normal voltage signal from the throttle pedal position sensor or switch 'D'. The throttle pedal position sensor is responsible for communicating the position of the accelerator pedal to the ECM, which then adjusts the throttle opening accordingly to control the engine's speed and performance.
Common Causes of P2123 2014 Toyota RAV4
- Faulty throttle pedal position sensor
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning ECM
- Mechanical issue with the throttle body
- Corrosion or contamination in the sensor circuit
Symptoms of P2123 2014 Toyota RAV4
- Reduced engine power
- Hesitation or stalling during acceleration
