P0094 - Fuel System Leak Detected – Small Leak

System Information

The ECM uses a Fuel Pressure Sensor and Fuel Pressure Regulator to monitor and control fuel pressure.

Fault Code Explained

The ECM has detected the fuel pressure is not as expected and has calculated that this is due to a system leak. This may be as a result of a drop in reported pressure from the fuel pressure sensor.

Recommended Tests

It is recommended to carry out a visual check for any signs of a fuel leak. If no visible leaks are found this fault code may be caused by a faulty sensor or wiring providing incorrect information to the ECM.
