Details of the Dodge p1db6 OBD Code

Dodge fault code P1DB6 relates to the transmission control module detecting an internal fault.

Dodge OBD code P1DB6 indicates an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit.

This code is triggered by the Engine Control Module (ECM) when it detects a malfunction in the EGR cooler bypass control circuit.

The EGR system is responsible for recirculating a portion of the engine’s exhaust gases back into the intake manifold to reduce emissions.

The EGR cooler bypass control circuit helps regulate the flow of exhaust gases through the EGR cooler.

When this circuit malfunctions, it can affect the performance and emissions of the vehicle.
