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.
Common Causes of P2140
- Faulty throttle position sensor.
- Faulty pedal position sensor.
- Wiring issues or poor connections in the sensor circuit.
- ECM malfunction or software glitches.
- Mechanical issues with the throttle body.
Symptoms of P2140
- Hesitation or lack of response when pressing the accelerator pedal.
- Rough idling or stalling while driving or at a stop.
- Reduced fuel efficiency.
- Check Engine Light illumination.
- Limited engine power or inability to accelerate.
How to Fix P2140
- Use a diagnostic scan tool to retrieve the trouble code and freeze frame data for further analysis.
- Inspect the throttle and pedal position sensors for proper operation and voltage output.
- Check the wiring harness and connectors for any signs of damage or corrosion.
- Replace any faulty sensors or repair wiring issues as necessary.
- Clear the trouble code from the ECM memory and perform a road test to verify that the issue has been resolved.
Cost to Fix P2140
The typical repair costs for addressing a Throttle/Pedal Position Sensor/Switch 'E'/'F' voltage correlation issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, you can expect to pay between $150 and $400 for parts and labor. Keep in mind that diagnostic time and labor rates can fluctuate based on location, vehicle make and model, and the complexity of the repair. It is advisable to consult with a trusted mechanic or auto repair shop to get an accurate estimate for your particular situation.
