The accelerator pedal sensor should be connected, the vehicle should have the ignition on and the engine
switched off:
– Check that the accelerator pedal value is:
PR030 = 0%: no load,
100% < PR030 < 120%: full load,
135% < PR030 < 145%: full load after pedal kickdown point.
If the value is not correct, replace the pedal sensor.

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.
