The automobile fault code P20DE indicates an issue with the nitrogen oxide (NOx) sensor circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them 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 P20DE code is related to the exhaust fuel addition injector assembly. This assembly is responsible for adding fuel by a control signal from the Engine Control Module (ECM). The code indicates a problem with the Exhaust Aftertreatment Fuel Pressure Sensor Circuit RangePerformance.

This sensor is crucial for the proper functioning of the exhaust fuel addition injector assembly. The P20DE code can affect two different controls: Particulate Matter (PM) forced regeneration and PM reduction.

If you encounter this fault code, it is recommended to have your vehicle inspected by a qualified mechanic.

What are the possible causes of the P20DE fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P20DE fault code. This code is usually caused by a faulty Exhaust Aftertreatment Fuel Pressure Sensor, an open or shorted Exhaust Aftertreatment Fuel Pressure Sensor harness, or a poor electrical connection in the Exhaust Aftertreatment Fuel Pressure Sensor circuit. 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 P20DE fault code?

If you’re experiencing the P20DE fault code, start by checking the “Possible Causes” listed above. 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. This will help you identify any issues with the Exhaust Aftertreatment Fuel Pressure Sensor harness, which could be causing the engine light to turn on.

What are the signs that the Exhaust Aftertreatment Fuel Pressure Sensor circuit has a poor electrical connection causing the P20DE fault code?

If the Exhaust Aftertreatment Fuel Pressure Sensor circuit has a poor electrical connection, it can cause the P20DE fault code. This is indicated by the Engine Light ON or Service Engine Soon Warning Light. To fix this issue, check for any open or shorted harnesses and 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.
