COOLANT TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the engine coolant temperature in °C.
NOTESSpecial notes:
Only apply the checks if the parameter is inconsistent.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
Check the condition of the coolant temperature sensor connections.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance between connections 3C and 3JK of component 244.
If the resistance of the coolant temperature sensor is not:
(theoretical values)
2140 Ω < X < 2364 Ω at 25°C,
771 Ω < X < 849 Ω at 50°C,
275 Ω < X < 291 Ω at 80°C,
replace the coolant temperature sensor (see MR 392, 385, 364, 370
and 417, Mechanical, 19A, Cooling,
Coolant temperature sensor: Removal - Refitting).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
