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 -

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).

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.

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.

TEST 10 Turbocharger solenoid valve check
Note:
No turbocharger control solenoid valve present on the K9K 740 engine for New Twingo and the K9K 800
engine for Kangoo 2.
Checking the vacuum at the pressure regulator inlet
Run the engine at idle speed.
Check the engine temperature using the CLIP parameter PR064 Coolant temperature.
Let the engine warm up until the temperature reaches 80
°C.
Disconnect the vacuum pipe from the end piece of the pressure regulator.
Connect a vacuum pressure gauge to the end of the disconnected pipe and put it in the vacuum measurement
position.
Perform a quick acceleration by depressing the accelerator pedal completely and then releasing it immediately.
The total duration of pressing and holding in the full load position must not exceed 1 second.
During this acceleration, the engine speed must reach a value between 3000 and 4000 rpm.
Repeat the operation 3 times.
Read the maximum vacuum posted by the pressure gauge during the increase and decrease in the speed and after
the return to idle speed.
Tolerance intervals for the vacuum are:
–1 bar < CORRECT vacuum value < - 0.6 bar
–0.6 bar < INCORRECT vacuum value < 0 bar
Is the vacuum at the turbocharging pressure regulator inlet displayed on the vacuum gauge within
the tolerance interval?
The solenoid valve is in order.
