[SOLVED] P2140 Code: How To Fix Throttle/Pedal Sensor Voltage Correlation

The P2140 automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light.

This code is caused by a faulty Accelerator Pedal Position Sensor, an open or shorted Accelerator Pedal Position Sensor harness, or a poor electrical connection in the Accelerator Pedal Position Sensor circuit. The Electric Throttle Control Actuator can also be the culprit.

The repair time for this issue is 1.0, and it is important to visually inspect the related wiring harness and connectors for any damage or corrosion. To interpret the fault code, check the “Possible Causes” listed above and follow the imperative steps to fix the issue.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2140 fault code. Here are the symptoms to look out for:

  • The P2140 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, engine misfires, rough idling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience stalling or difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p2140 can be caused by a range of issues, including a faulty sensor and poor electrical connections.

  • The automobile fault code P2140 can be caused by a faulty Accelerator Pedal Position Sensor.
  • It can also be caused by an open or shorted Accelerator Pedal Position Sensor harness.
  • Another cause can be a poor electrical connection in the Accelerator Pedal Position Sensor circuit.
  • Lastly, a faulty Electric Throttle Control Actuator can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2140, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2140, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2140 indicates a problem with the fuel injector group A supply voltage circuit.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the fixing cost of P2140 will range between $75 and $150, depending on the repair time required to fix the issue.

The P2140 code is related to the Accelerator Pedal Position (APP) sensor. The sensor has two pedal position signals, APP and APP2, which have a positive slope and increase at different rates. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals.

If the APP sensor inputs APP1 and APP2 disagree on the position of the accelerator pedal by more than an expected value, the P2140 code is set.

This code indicates a ThrottlePedal Position SensorSwitch ‘EF’ Voltage Correlation issue.

What are the possible causes of the automobile fault code P2140?

If you see the engine light on or the service engine soon warning light, it could be due to the P2140 fault code. This code is usually caused by a faulty accelerator pedal position sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a faulty electric throttle control actuator. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2140 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2140 fault code, there are a few things you can do to fix it. First, check for a faulty Accelerator Pedal Position Sensor or Electric Throttle Control Actuator. Then, visually inspect the related wiring harness and connectors for any damage or poor electrical connections. Look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify and fix the issue quickly and efficiently.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2140 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P2140 fault code, follow these steps: visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. Check the “Possible Causes” listed above and ensure that the Accelerator Pedal Position Sensor harness is not open or shorted, and that the Accelerator Pedal Position Sensor circuit has a good electrical connection. Finally, ensure that the Electric Throttle Control Actuator is not faulty.
