Checking the Status
Checking The Status
- Start and run the engine to operating temperature.
Check whether the fault is permanent or intermittent by reading off the signal from the fuel pressure sensor. Check that the value is within its permitted range. The value must be 480 ±5 kPa when idling, with the engine at operating temperature and in neutral. The pressure must drop with the ignition off.
The fault is permanent if the value is not within its permitted range. If the value is within its permitted range, this indicates that the fault is intermittent and not presently active.
