Check the entire air inlet circuit:
– air filter unit inlet not blocked and filter not clogged,
–no foreign bodies on the air flow sensor grille (visual inspection only).
Otherwise, replace the air flow sensor.
– oil vapour recirculation circuit connected correctly,
–no leaks or blockages in the low and high pressure air circuits: pipes, presence and tightness of the mounting
clips, mounting of the turbocharger pressure sensor, intercooler, etc.
– check that the damper valve is open (valve control is against the body of the air vent unit).
With the flowmeter connected, the vehicle ignition on and engine stopped:
– check the voltage between tracks 2 and 5 of the flowmeter:
If the value is not 0.6 V ± 0.1, replace the air flow sensor.

●Check the EGR valve is not jammed open:
– remove the EGR valve:
– with the valve removed and connected, run command AC002 EGR valve.
Check: the movement of the valve,
that it closes when the command is completed.
If these checks show that the valve is jammed or irrevocably seized, replace the EGR valve.
If no faults are revealed, but the fault is still present, replace the air flowmeter.

STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine is started or following a road test.
A) Make sure the water in diesel fuel detection sensor is properly connected.
– If not, clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
– If the fault does not recur, end the fault finding procedure.
– If the fault does recur, go to step B.
B) If the sensor is properly connected:
– drain the diesel filter unit (seeMR 364, 13A, Fuel supply),
– clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
If the fault does not recur, end the fault finding procedure.
C) If the fault recurs:
–Check the continuity and the absence of unwanted resistance on the connection between:
Injection computer, grey 32-track connector C, track A2 Track 3 of the water detection sensor
–Check the power supply to the water detection sensor:
UPC PPM1 black connector track 2 Track 1 the water detection sensor
Earth Track 2 water detection sensor
– Carry out the necessary repairs.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 364, 13A, Fuel supply).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds,
to confirm the repair.
Note:
if the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (on a bend,
leaning) may causethe injection warning light to light up erratically.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.
