Sensor electrical conformity
Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts, run test 5 Inlet circuit check):
–air filter unit inlet not blocked and filter not clogged,
–oil vapour recirculation circuit connected correctly,
–low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc., run TEST 1 Low pressure circuit check and TEST 7
High pressure circuit sealing check
–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 (or 3FB3) of component 799.
Check the continuity and absence of interference resistance of the following connections:
–3DV,
–3DW, between components 120 and 799.
Flowmeter connected, vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV of component 799.
If the voltage is not between 0.3 V and 0.7 V, replace the air flowmeter, component code 799 (see MR 364 (Mégane
II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2),

PR873OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle distance in km when the warning requesting the
oil change was displayed on the instrument panel.
NOTESThis parameter is not to be interpreted:
–on the K9K812 engine,
–if PR873 = 0 (Vdiag 58 only).
Conformity check: Engine stopped, ignition on or engine running.
The oil status is calculated by the oxidation program in the injection computer, depending on the engine revs.
When this count reaches a certain threshold before the end of the oil change period, the injection computer sends
a signal to the instrument panel, which will display "service required soon". PR873 corresponds to the vehicle
distance at the time this signal is sent.
The instrument panel computer will then count 900 miles (1500 km) before displaying the message "service
required".
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an oil change
within the remaining 900 miles (1500 km).

PR932DEGREE OF ENGINE OIL DILUTION
PARAMETER
DEFINITIONThis parameter gives the value for the degree of oil wear in %.
NOTESThis parameter is not to be interpreted:
–on the K9K812 engine,
–if PR932 = 0 (Vdiag 58 only).
Conformity check: Engine stopped, ignition on or engine running.
PR932 = 0% for the first 900 miles (1500 km), beyond this value the PR932 changes regularly until it
reaches 100%.
If PR932 = 100% it means that the oil should be changed.

PR1015OIL SERVICE INTERVAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle distance before the next oil change in miles (km).
NOTES–This parameter is not to be interpreted:
–on the K9K812 engine,
–if PR1015 = 50000 (Vdiag 58 only).
Conformity check: Engine stopped, ignition on or engine running.
20000 km < PR1015 < 0 km.
This parameter decreases to 0 according to the vehicle distance and the degree of oil wear.
