Code P2122 2016 Toyota RAV4 Description
The P2122 diagnostic trouble code for a 2016 Toyota RAV4 indicates a problem with the Throttle Pedal Position Sensor/Switch 'D' Circuit Input being low. This sensor is responsible for monitoring the position of the throttle pedal and sending signals to the engine control module (ECM) to adjust the throttle opening accordingly. When the sensor detects that the voltage signal is lower than the specified range, it triggers the P2122 code.
Common Causes of P2122 2016 Toyota RAV4
- Faulty throttle pedal position sensor
- Damaged wiring or connectors
- Corrosion in the electrical connections
- Issues with the ECM
- Environmental factors such as moisture or debris affecting sensor performance
Symptoms of P2122 2016 Toyota RAV4
- Reduced engine power
- Poor acceleration
- Check Engine Light illuminated
- Rough idling
- Stalling
