P1178 Fault Code: Understanding The Description And Troubleshooting Steps
The P1178 fault code indicates an error in the fuel pump control module’s fuel level sensor internal supply circuit. This circuit is responsible for providing power to the sensor that measures the fuel level in the vehicle. The Fuel Pump Power Control Module constantly communicates with the Engine Control Module (ECM) to monitor the fuel pump power control system’s operation.
It sends serial data messages in a rolling count series with password-protected samples. When the ECM detects a problem with the fuel pump control module’s internal supply circuit for the fuel level sensor, it triggers the P1178 fault code.
This code helps identify and diagnose issues related to the fuel pump driver control module sensor 1 internal supply circuit.
