If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2139 fault code. Here are the symptoms to look out for:

  • The P2139 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 a decrease in engine power, hesitation or stalling while driving, difficulty starting the engine, and poor fuel economy.
  • Additionally, the throttle may become unresponsive or may respond inconsistently, and the vehicle may experience sudden acceleration or deceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2139 fault code can be caused by a faulty sensor, poor electrical connection, or a malfunctioning actuator.

  • The automobile fault code P2139 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 the P2139 fault code.

To fix the p2139 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2139, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2139 is related to the throttle or pedal position sensor. The diagnosis involves checking the wiring and connections of the sensor, as well as testing the sensor itself.

The fixing cost will depend on the severity of the issue and the repair time required.

The estimated repair time for this fault code is 1.0 hour. Most auto repair shops charge between $75 and $150 per hour, which will affect the fixing cost.

It is important to address this issue promptly to avoid further damage to the vehicle and ensure safe driving.

The P2139 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 but 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 P2139 code is set.

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

What are the possible causes of the automobile fault code P2139?

If you see the engine light on or the service engine soon warning light, it could be due to the P2139 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 P2139 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2139 fault code, there are a few things you can do to fix it. First, check the possible causes, which include a faulty Accelerator Pedal Position Sensor, an open or shorted harness, poor electrical connection, or a faulty Electric Throttle Control Actuator. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What are the symptoms of the P2139 fault code and how urgent is it to fix it?

The P2139 fault code is indicated by the Engine Light ON or Service Engine Soon Warning Light. It is caused by a faulty Accelerator Pedal Position Sensor, open or shorted harness, poor electrical connection, or a faulty Electric Throttle Control Actuator. It is important to fix this issue as soon as possible to avoid potential safety hazards and further damage to the vehicle. To fix it, check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.
