P105A Fault Code: Understanding The Description And Troubleshooting Tips
The P105A fault code refers to a problem with the reductant pump motor in your automobile. The reductant pump motor is controlled by the reductant control module, which receives commands from the Engine Control Module (ECM).
The ECM checks the wire connection to the reductant control module for circuit continuity.
If the reductant control module detects that the reductant pump rotor is stalled for more than 5 seconds, it will set the P105A code. This code indicates that the reductant pump speed is too low. It is important to address this issue promptly to ensure proper functioning of the reductant system in your vehicle.
FAQ
