PR041
CONTINUED
Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 Atmospheric pressure by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between
the 2 vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure
sensor.
If the difference between PR041 and PR035 Atmospheric pressure is less than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
absence of leaks or blockages in the low and high pressure air circuit: ducts, presence and tightness of the
mounting clips, mounting of the turbocharger pressure sensor, intercooler, etc.
Check that the damper valve is not jammed closed.
Repair if necessary.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
