Checking the status

Check whether the fault is permanent or intermittent by reading off the signal from the fuel pressure sensor.

Check that the signal is within its permitted range. The signal is measured in the fuel rail for the injectors.

The fault is permanent if the signal is incorrect.

The fault is intermittent if the signal is correct.
