STATUS
DEFINITION
Statuses ET742 to ET751 correspond to the causes for the regeneration request. They
are associated with the parameters PR816 Stored regeneration start No. 1 to PR825
Stored regeneration start No. 10 which contain the record of the vehicle mileage at
the start of regeneration (e.g. PR745 Stored regeneration start No. 4 is associated
with ET745).
NOTESSpecial notes:
These statuses should only be interpreted for ALP 9 Particle filter warning light
comes on too frequently.

Sensor electrical conformity
Check the air inlet circuit (from the air filter inlet to the inlet manifold,
apply Test 4 Turbocharged air inlet circuit check):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, apply Test 4 of ALP 2 Starting fault or starting impossible,
– oil vapour recirculation circuit connection conformity.
–absence of 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 not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
•3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
•3FB of component 799.
Check the continuity and absence of interference resistance of the following connections:
•3DV between components 120 and 799,
•3DW between components120 and 799.
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.
With the flowmeter connected, the vehicle ignition on, and the engine stopped:
Check the voltage between connections 3DW and 3DV of component 799.
If the air flow sensor voltage is not between 0.3 V < X < 0.7 V, replace the sensor.
