Code P2140 Description

The diagnostic trouble code P2140 indicates a problem with the Throttle/Pedal Position Sensor/Switch 'E'/'F' voltage correlation. This means that the Engine Control Module (ECM) has detected a discrepancy between the voltage signals from the throttle position sensor and the pedal position sensor for throttle control. The throttle position sensor is responsible for monitoring the position of the throttle blade, while the pedal position sensor detects the position of the accelerator pedal. When these sensors do not correlate, it can lead to issues with engine performance, fuel efficiency, and overall drivability.
