Code P2140 Dodge Description
The P2140 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Throttle/Pedal Position Sensor/Switch 'E'/'F' voltage correlation. This means that there is a discrepancy between the voltage readings of the throttle pedal position sensor or switch 'E' and 'F', which are crucial components for the proper operation of the vehicle's throttle system.
Common Causes of P2140 Dodge
- Faulty throttle pedal position sensor
- Wiring or connection issues in the throttle position sensor circuit
- ECM/PCM malfunction
- Corrosion or contamination in the sensor connectors
- Mechanical issues affecting the throttle system
Symptoms of P2140 Dodge
- Erratic throttle response
- Engine hesitation or surging
- Stalling or difficulty starting the engine
- Reduced fuel efficiency
- Limp mode activation
How to Fix P2140 Dodge
- Begin by performing a thorough inspection of the throttle position sensor 'E' and 'F' connectors and wiring harness. Check for any signs of damage, corrosion, or loose connections.
- Use a multimeter to test the voltage output of both throttle position sensors while operating the accelerator pedal. Compare the readings to determine if there is a correlation issue.
- If the sensors are providing inconsistent voltage readings, replace both throttle position sensors to ensure proper operation.
- Clear the DTC from the ECM/PCM memory using a diagnostic scan tool and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnosis may be required to identify any underlying issues with the throttle system or ECM/PCM.
Cost to Fix P2140 Dodge
The typical repair costs for addressing a P2140 code can vary depending on the specific cause of the issue. Replacement throttle position sensors for a Dodge vehicle can range from $50 to $150 each, depending on the model and year. Labor costs for sensor replacement and diagnostic time can add an additional $100 to $300, bringing the total repair cost to approximately $200 to $600. However, it is essential to note that labor rates and parts prices can vary significantly based on the location and the repair shop's rates. It is advisable to obtain a detailed quote from a trusted mechanic or dealership to get a more accurate estimate.

Frequently Asked Questions about P2140 Dodge Code
1. What does the OBDII code P2140 mean on a Dodge vehicle?
P2140 indicates a voltage correlation issue between the Throttle/Pedal Position Sensor 'E' and 'F', meaning the sensor signals do not match as expected.
2. What are the common symptoms of the P2140 code in a Dodge?
Symptoms may include reduced engine performance, limp mode activation, erratic throttle response, or the check engine light turning on.
3. What causes the P2140 code to appear in a Dodge?
Possible causes include a faulty throttle or pedal position sensor, damaged wiring or connectors, or issues with the vehicle's Powertrain Control Module (PCM).
4. Can I drive my Dodge with the P2140 code?
Driving with the P2140 code may be possible but not recommended, as it could lead to reduced performance and potentially unsafe driving conditions.
5. How do I diagnose the P2140 code on my Dodge?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the throttle and pedal position sensors, checking for damaged wiring, and testing electrical connections.
6. How do I fix the P2140 code on a Dodge vehicle?
Repairs may include replacing the faulty throttle or pedal position sensor, repairing damaged wiring, cleaning electrical connections, or reprogramming the PCM if needed.
7. How much does it cost to fix the P2140 code in a Dodge?
Repair costs vary but typically range from $100 to $400 depending on whether the sensor, wiring, or PCM requires attention.
8. Can a dirty throttle body cause the P2140 code?
A dirty throttle body is not a direct cause of P2140 but can contribute to throttle-related issues that should be checked during diagnosis.
9. Will resetting the PCM fix the P2140 code in my Dodge?
Resetting the PCM may temporarily clear the code, but the underlying issue must be resolved to prevent the code from returning.
10. What tools are needed to troubleshoot the P2140 code in a Dodge?
You’ll need an OBDII scanner, a multimeter for electrical tests, and potentially a throttle body cleaner if cleaning is necessary during diagnosis.
