PR730AIR FLOW SENSOR TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the air temperature of the flowmeter in °C.
NOTESSpecial notes:
Depending on the engine type, the air temperature is given by the air flowmeter or the
exterior air temperature sensor.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
Check the condition of the air flow sensor connections.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If necessary, replace the sensor (see MR 364 (Mégane II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), MR 417 (Kangoo 2), Mechanical, 12A, Fuel mixture, Air flowmeter: Removal -
Refitting).
Measure the resistance between the following connections:
(vehicle with flowmeter)
–3B and 3DW of component 799;
(vehicle without flowmeter)
–3PB and 3KQ of component 272,
–3SH and 3KQ of component 272,
–3JQ and 3KQ of component 272.
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 the wiring.

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).

PR878FAST IDLE SPEED
PARAMETER
DEFINITIONThis parameter indicates the fast idle speed in rpm.
NOTESSpecial notes:
It is possible to modify the value of the PR878 using the command SC041 Modification
of the commercial vehicle idle speed.
This parameter is valid only on Kangoo 2.
Conformity check: Engine stopped, ignition on or engine running.
If the function was activated (ET800 Fast idle function ACTIVE status), PR878 shows the value of fast idle
speed in rpm.
It is possible to modify the value using command SC041 Changing VU idle speed.
The idle speed values that can be modified are: 1000, 1100, 1200, 1300 rpm.

PR879MAXIMUM AUTHORISED SPEED
PARAMETER
DEFINITIONThis parameter indicates the maximum authorised speed in mph (km/h) requested by
the customer using command SC040 Speed limiter.
NOTESSpecial notes:
It is possible to modify the value of PR879 using command SC040 Speed limiter.
This parameter is valid only on Kangoo 2.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
If ET741 "Optional vehicle speed restriction" is ACTIVE, the value of PR879 is between 18 mph (30 km/h) and
150 mph (250 km/h).
In the event of a fault or modification of this speed, use command SC040 Speed limiter.

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.

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.
