The P1379 fault code indicates that the Engine Control Module (ECM) has detected an incorrect voltage level at the Fuel Injection Control Module (FICM).

This means that there is a problem with the circuit that controls the fuel injection system in your vehicle.

When the voltage level at the FICM is too high, it can cause issues with the fuel injection process. This can lead to poor engine performance, reduced fuel efficiency, and potentially even engine damage if left unresolved. To fix this issue, you will need to diagnose the specific cause of the high voltage in the FICM circuit.

This may involve checking the wiring and connections, testing the FICM itself, or inspecting other related components.

It is recommended to consult a qualified mechanic or use a diagnostic tool to accurately identify and resolve the problem.
