Code P0120 2015 Toyota RAV4 Description

The P0120 diagnostic trouble code (DTC) for a 2015 Toyota RAV4 indicates a Throttle/Pedal Position Sensor/Switch 'A' Circuit Malfunction. This code is triggered when the Engine Control Module (ECM) detects a discrepancy between the actual position of the throttle or accelerator pedal and the expected position based on input from the sensor or switch. The throttle or pedal position sensor is crucial for the ECM to determine the appropriate fuel delivery and air intake for optimal engine performance.
