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.
