[SOLVED] P042E Code: Fixing Exhaust Gas Recirculation Closed Position Performance

The automobile fault code P042E indicates a problem with the Exhaust Gas Recirculation (EGR) Valve. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause could be a faulty EGR valve, an open or shorted EGR valve harness, a poor electrical connection in the EGR valve circuit, or a faulty Engine Control Module (ECM).

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0.

It is important to address this fault code promptly to prevent further damage to the vehicle.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p042e fault code.

  • The symptoms of the automobile fault code P042E include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P042E can be caused by a faulty EGR valve, open or shorted EGR valve harness, poor electrical connection in the EGR valve circuit, or a faulty ECM.

  • The fault code P042E can be caused by a faulty Exhaust Gas Recirculation (EGR) Valve, an open or shorted harness for the EGR Valve, a poor electrical connection in the EGR Valve circuit, or a faulty Engine Control Module (ECM).

To fix the p042e fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P042E, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix typically takes around 1.0 hour to complete.

The automobile fault code P042E can be diagnosed and fixed within an estimated repair time of 1.0 hour.

Most auto repair shops typically charge between $75 and $150 per hour for this service.

The P042E fault code relates to the Exhaust Gas Recirculation (EGR) system in your vehicle. The Engine Control Module (ECM) uses the EGR position sensor to determine the position of the EGR valve.

The ECM sends a reference voltage to the sensor and receives a signal based on the EGR valve position.

When the ECM detects that the desired position and the actual position of the EGR valve are greater than a calibrated threshold, the P042E code is triggered. This means that the EGR valve is not closing properly, affecting the performance of the EGR system. To resolve this issue, you will need to perform a closed position performance test on the EGR system.

This involves checking the voltage readings from the EGR position sensor and comparing them to the desired position. If the readings are outside the calibrated threshold, you may need to replace the EGR valve or repair any wiring or connection issues. It is important to address this fault code promptly to ensure the proper functioning of your vehicle’s EGR system.

How can a faulty Exhaust Gas Recirculation (EGR) Valve cause the engine light to turn on?

When the engine light turns on, it could be due to a faulty Exhaust Gas Recirculation (EGR) Valve. This can happen if the EGR valve harness is open or shorted, if there is a poor electrical connection in the EGR valve circuit, or if the Engine Control Module (ECM) is faulty. To fix this issue, you should check the possible causes mentioned above. Take a visual inspection of the wiring harness and connectors, looking for any damage or broken, bent, pushed out, or corroded pins in the connectors.

What steps should be taken to visually inspect the wiring harness and connectors related to the Exhaust Gas Recirculation Valve?

To visually inspect the wiring harness and connectors related to the Exhaust Gas Recirculation Valve, follow these steps. First, check for the symptom of the Engine Light ON or Service Engine Soon Warning Light. Next, identify the cause, which could be a faulty EGR valve, an open or shorted EGR valve harness, a poor electrical connection in the EGR valve circuit, or a faulty Engine Control Module (ECM). Finally, to fix the issue, visually inspect the wiring harness and connectors for any damaged components, and look for broken, bent, pushed out, or corroded connector pins.

Why is it important to check for damaged components and inspect the connector’s pins when troubleshooting the P042E fault code?

When troubleshooting the P042E fault code, it is crucial to check for damaged components and inspect the connector’s pins. This is because a faulty Exhaust Gas Recirculation (EGR) Valve, an open or shorted EGR valve harness, a poor electrical connection in the EGR valve circuit, or a faulty Engine Control Module (ECM) can all cause this issue. By visually inspecting the wiring harness and connectors, you can identify any broken, bent, pushed out, or corroded pins, which may be the root cause of the problem. Don’t forget to check the “Possible Causes” listed above for a comprehensive fix.
