Use a voltmeter to measure the voltage between tracks 1 and 3 of the camshaft sensor:
The voltage displayed should be equal to the battery voltage 0.08 V)
if the voltage is outside permitted tolerance values, take the measurement again with the camshaft sensor
disconnected.
If the voltage is still outside the permitted tolerance values with the sensor disconnected, check the continuity and
absence of interference resistance on the following connection:
Camshaft sensor, track 3 Track 2, PPM1 UPC black connector
If the voltage displayed is correct with the sensor disconnected, replace the camshaft sensor.
If the fault is still present, check the timing adjustment.

Check the continuity and absence of interference resistance of the following connections:
UPC PPM1 connector, track 1 Track 1 EGR solenoid valve
Injection computer, brown 48-track connector B, track L2 Track 5 EGR solenoid valve
Check that there are no leaks on the EGR circuit (pipes pierced or damaged) and that the clamps are properly
tightened.
Check the operation of the EGR valve:
– exit fault finding mode in CLIP,
– switch off the vehicle ignition,
– disconnect the EGR valve connector,
– remove the EGR valve,
– disconnect the connector and EGR valve,
– switch on the ignition and return to fault finding mode on the CLIP tool,
– run command AC002 EGR solenoid valve with valve removed.
Check:
– the position of the valve,
– that there is no play between the valve and the control rod, and the general condition (clogging, hard point, etc.),
– the valve closure when the command is completed.
If, during the command:
– no valve movement is evident,
– the valve does not open or close completely,
Check that there are no particles blocking the movement of the piston.
If a particle was blocking the movement of the valve, run command AC002 EGR solenoid valve, again and check
the valve is operating correctly.
If the valve is operating normally, run command RZ002 EGR Adaptives to reinitialise the valve operating values.
If the valve is jammed or irrevocably seized, replace the EGR valve.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
