Code P0122 2013 Toyota RAV4 Description

The P0122 diagnostic trouble code (DTC) for a 2013 Toyota RAV4 refers to an issue with the Throttle/Pedal Position Sensor/Switch 'A' Circuit having a low input signal. This sensor is crucial for the proper functioning of the vehicle's electronic throttle control system. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
