  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P20DB can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the P20DB fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P20DB code is related to the exhaust fuel addition injector assembly. This assembly is responsible for adding fuel to the exhaust system. The code indicates that the exhaust aftertreatment fuel supply control is stuck open.

This can cause issues with particulate matter forced regeneration and PM reduction. The Engine Control Module (ECM) sends a control signal to the injector assembly. Low-pressure fuel is supplied to the injector assembly by the feed pump in the supply pump assembly.

What are the possible causes of the P20DB automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P20DB 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 wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
