The P20E0 fault code can be caused by a faulty sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P20E0 can be caused by a faulty Exhaust Aftertreatment Fuel Pressure Sensor.
  • It can also be caused by an open or shorted Exhaust Aftertreatment Fuel Pressure Sensor harness.
  • Additionally, a poor electrical connection in the Exhaust Aftertreatment Fuel Pressure Sensor circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code: p20e0, including inspecting wiring harness, connectors, and damaged components.

  • To fix the automobile fault code P20E0, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage or corrosion.
  • 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 P20E0 indicates an issue with the Reductant Heater A Control Circuit. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P20E0 code refers to the exhaust aftertreatment fuel pressure sensor circuit being high. The exhaust fuel addition injector assembly is responsible for adding fuel by a control signal from the Engine Control Module (ECM). This injector is used for two different controls: Particulate Matter (PM) forced regeneration and PM reduction.

What are the possible causes of the P20E0 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P20E0 fault code. This code is usually caused by a faulty exhaust aftertreatment fuel pressure sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the 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 P20E0 fault code?
