Check the continuity and absence of interference resistance of the following connections:
•3LQ between components 120 and 1071,
•3LP between components 120 and 1071,
•3LN between components 120 and 1071.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Vehicle with the ignition on, and the engine stopped for at least 1 minute:
Compare the values of PR041 Turbocharging pressure and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 is greater than 0.1 bar,
check the value of PR035 by comparing it with the reading on a vehicle in the workshop which is correct.
If the value of PR035 is not correct (difference greater than 0.1 bar between the 2 vehicles), contact the Techline.
Otherwise (when the value of PR035 is correct), replace the turbocharger pressure sensor.
If the difference between PR041 and PR035 is less than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035.
If the difference between PR041 and PR035 is greater than 0.2 bar.
Check the air inlet circuit:
Apply Test 4 Turbocharged air inlet circuit check.
Low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc.
Check that the damper valve is not jammed closed.
Repair if necessary.
