NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present:
–when an attempt is made to start the engine,
–when the engine is running.
Special notes:
The atmospheric pressure sensor is integrated into the injection computer and cannot
be separated.
If the fault is present:
–there is light smoke at the exhaust,
–the atmospheric pressure value changes to safe mode, PR035 Atmospheric
pressure = 750 mbar.
–the level 1 warning light is lit,
–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
Disconnect the injection computer and check the condition of the contacts and connector.
Repair if necessary.
Display the value of parameter PR041 Turbocharger pressure.
If this value is stuck at 750 mbar, refer to interpretation of fault DF004 Turbocharging pressure sensor circuit.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
