The P0A21 fault code refers to the Motor Torque Sensor Circuit Intermittent issue.

This code is set by the Engine Control Module (ECM) when it detects that the Motor Torque Sensor is not functioning within the factory specifications.

The Motor Torque Sensor is responsible for monitoring the torque produced by the motor. When this sensor experiences intermittent problems, it can lead to inaccurate readings and affect the overall performance of the vehicle. It is important to address this issue promptly to ensure optimal engine performance and avoid potential damage.
