The P20E2 automobile fault code indicates a problem with the Exhaust Gas Temperature Sensor, which can cause the engine light to turn on. The possible causes of this issue include a faulty sensor, open or shorted sensor harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this problem, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

The repair time for this issue is estimated to be around 1.0.

It is important to interpret the fault code correctly to ensure that the issue is resolved effectively.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour

If you notice the engine light on or service engine soon warning light, it could be a sign of the P20E2 fault code.

Here are some symptoms to look out for:

  • The P20E2 fault code in automobiles 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, decreased fuel efficiency, rough idling, and difficulty starting the engine.
  • Additionally, the vehicle may experience stalling or hesitation during acceleration, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The P20E2 automobile fault code can be caused by various factors, including…

  • The automobile fault code P20E2 can be caused by a faulty Exhaust Gas Temperature Sensor.
  • It can also be caused by an open or shorted Exhaust Gas Temperature Sensor harness.
  • Poor electrical connection in the Exhaust Gas Temperature Sensor circuit can also trigger this fault code.
  • Additionally, Exhaust leaks can cause P20E2.
  • Finally, excessive particulate matter buildup on the sensor can also be a cause of this fault code.

Below are the possible fixes for the automobile fault code p20e2, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P20E2, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P20E2 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the cost of fixing the P20E2 fault code can range from $75 to $150, depending on the repair time required.

The P20E2 code is related to the Exhaust Gas Temperature Sensor (EGTS).

The EGTS detects exhaust gas temperature and converts it into a voltage. The PCM sets the P20E2 code when the EGTS is out of factory specifications.

The code indicates a correlation issue between the EGTS 12 in Bank 1. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) andor in front of the Diesel Particulate Filter (DPF).

The PCM continuously monitors the EGTS for proper circuit continuity and out of range high values. The P20E2 code is an OBDII code that helps to control engine conditions to effectively reduce emissions.

What are the possible causes of the P20E2 automobile fault code?

If you’re experiencing the P20E2 fault code, your engine light may be on. This could be due to a faulty exhaust gas temperature sensor, an open or shorted sensor harness, poor electrical connection in the sensor circuit, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P20E2 fault code?

If you’re experiencing the P20E2 fault code, which is indicated by the engine light being on, you may have a faulty exhaust gas temperature sensor, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. 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.

What are the consequences of ignoring the P20E2 fault code?

Ignoring the P20E2 fault code, which indicates a faulty Exhaust Gas Temperature Sensor, can lead to serious consequences such as reduced fuel efficiency, increased emissions, and potential damage to the engine and exhaust system. It is important to address the issue promptly by visually inspecting the related wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.
