Code P2122 Ford Description

The P2122 Ford diagnostic trouble code (DTC) indicates a problem with the Throttle/Pedal Position Sensor/Switch 'D' Circuit being too low. This sensor is responsible for monitoring the position of the throttle pedal in relation to the throttle body, allowing the engine control module (ECM) to adjust the throttle opening accordingly. When this circuit is detected to be low, it means that the sensor is not sending the expected voltage signal to the ECM, which can lead to various performance issues in the vehicle.
