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.

PR873OIL OXIDATION SIGNAL
STATUS
DEFINITIONThis parameter indicates the vehicle distance in miles (km) when the oil oxidation
threshold is reached.
NOTESThis parameter should only be interpreted if the OCS (Oil Control System) program is
activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Conformity check: Engine stopped and the ignition on, or Engine running and the engine coolant
temperature > 80°C without electrical consumers
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer sends
a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to the vehicle
mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service
required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).
