The fault code P20D5 indicates an issue with the reductant heater control 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 P20D5 code refers to a problem with the exhaust aftertreatment fuel injector ‘B’. This injector is responsible for adding low-pressure fuel to the exhaust fuel addition injector assembly.

The Engine Control Module (ECM) sends a control signal to the injector for two different controls: Particulate Matter (PM) forced regeneration and PM reduction. If the injector is stuck in the ‘on’ position, it can cause issues with the fuel mixture and potentially lead to further engine problems.

What are the possible causes of the P20D5 automobile fault code?

If your engine light is on and you’re seeing the P20D5 fault code, it could be due to a faulty exhaust aftertreatment fuel injector, an open or shorted harness, or a poor electrical connection in the exhaust aftertreatment fuel injector circuit. To fix the issue, you should visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can one visually inspect the related wiring harness and connectors to fix the P20D5 fault code?

If you’re experiencing the P20D5 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Exhaust Aftertreatment Fuel Injector or an open or shorted Exhaust Aftertreatment Fuel Injector harness. 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. This will help you identify any issues and determine the best course of action to take.

What are the consequences of ignoring the P20D5 automobile fault code?

Ignoring the P20D5 fault code in your automobile can lead to serious consequences. The engine light or service engine soon warning light will remain on, indicating a faulty exhaust aftertreatment fuel injector. This can result in poor engine performance, reduced fuel efficiency, and even engine damage. It is important to visually inspect the related wiring harness and connectors, and check for damaged components to avoid further complications.
