The fault code P20DA indicates an issue with the reductant heater control circuit.

The diagnosis process involves checking the wiring and connections, as well as testing the reductant heater control module. The estimated repair time for this issue is 1.0 hour. The cost of fixing this fault code can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour for labor.

Other factors that may influence the cost include the cost of replacement parts and any additional repairs that may be needed.

The P20DA code is related to the exhaust fuel addition injector assembly. This injector assembly is responsible for adding fuel by a control signal from the Engine Control Module (ECM). The P20DA code indicates that there is a high circuit issue with the exhaust aftertreatment fuel supply control.

This code can affect two different controls: Particulate Matter (PM) forced regeneration and PM reduction.

The low-pressure fuel is supplied to the exhaust fuel addition injector assembly by the feed pump in the supply pump assembly.

What are the possible causes of the P20DA automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P20DA fault code. This code is caused by a faulty exhaust aftertreatment fuel supply control, an open or shorted harness, or a poor electrical connection in the exhaust aftertreatment fuel supply control 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.
