[SOLVED] P20Ce Code: High Voltage Exhaust Aftertreatment Fuel Injector Fix

The P20CE automobile fault code indicates a problem with the Exhaust Aftertreatment Fuel Injector.

The most common symptom is the Engine Light turning on.

The cause of this issue could be a faulty injector, an open or shorted harness, poor electrical connection, or a faulty Engine Control Module. The importance of repairing this issue lies in the fact that it can lead to decreased engine performance and increased emissions. The difficulty of the repair is moderate, with a repair time of 1.0.

To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of the P20CE fault code.

Here are the symptoms to look out for:

  • The P20CE 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 reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience a decrease in acceleration or a loss of power while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P20CE automobile fault code can be caused by a faulty fuel injector, poor electrical connection, or a faulty ECM.

  • The automobile fault code P20CE can be caused by a faulty exhaust aftertreatment fuel injector.
  • It can also be caused by an open or shorted exhaust aftertreatment fuel injector harness.
  • Poor electrical connection in the exhaust aftertreatment fuel injector circuit can also trigger this fault code.
  • Lastly, a faulty engine control module (ECM) can also be a cause of the P20CE fault code.

Below are some possible fixes for the automobile fault code p20ce, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P20CE, you need to check the possible causes listed above.
  • 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 fix will take an estimated repair time of 1.0 hour.

The automobile fault code P20CE has an estimated repair time of 1.0 hour. The cost of fixing this code varies depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. These factors are influential in determining the overall cost of diagnosing and fixing the P20CE fault code.

The P20CE fault code is related to the exhaust fuel addition injector assembly. This injector is responsible for two different controls: Particulate Matter (PM) forced regeneration and PM reduction.

When the Engine Control Module (ECM) detects a fault on either of the exhaust aftertreatment fuel injector circuits, it sets a Diagnostic Trouble Code (DTC) for P20CE. This fault code specifically indicates a high voltage issue in the exhaust aftertreatment fuel injector control circuit.

What are the possible causes of the P20CE automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P20CE fault code. This code is usually caused by a faulty Exhaust Aftertreatment Fuel Injector, an open or shorted Exhaust Aftertreatment Fuel Injector harness, a poor electrical connection in the Exhaust Aftertreatment Fuel Injector circuit, or a faulty Engine Control Module (ECM). 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 P20CE fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P20CE fault code, there are a few possible causes to consider. One of them is a faulty Exhaust Aftertreatment Fuel Injector, which could be caused by an open or shorted harness, poor electrical connection, or a faulty Engine Control Module (ECM). To fix this issue, you should visually inspect the related wiring harness and connectors for any damaged components or broken, bent, pushed out, or corroded pins.

Is a faulty Engine Control Module (ECM) a common cause of the P20CE fault code?

While a faulty Engine Control Module (ECM) is listed as a possible cause of the P20CE fault code, it is not a common cause. The most common cause of this fault code is a faulty Exhaust Aftertreatment Fuel Injector or issues with its wiring harness or circuit connection. To fix the issue, one should visually inspect the related wiring harness and connectors, checking for damaged components and broken or corroded pins.
