Verification with manometer

HINT: After carrying out the repair, check that the fault has been remedied.

CAUTION:

The pressure in the fuel injection system can reach approximately 650 kPa when this diagnostic trouble code (DTC) is stored. Use an adapted manometer.

Connect the manometer. See Fuel pressure gauge
Run the engine to operating temperature. Allow the engine to idle
Air conditioning (A/C) off.
Read off the relative fuel pressure.

The relative fuel pressure is calculated from the fuel pressure sensor and the atmospheric pressure sensor signal (= absolute pressure minus atmospheric pressure).

Check that the value on the manometer and the value displayed in VIDA are the same. If the values are different, this indicates incorrect function.
