NOTESConditions for application to a stored fault:
The fault is declared present after the ignition has been switched on for at least
10 seconds.
If the fault is present:
– the engine overheating warning light is lit on the instrument panel,
– the fan assemblies are running,
– the air conditioning compressor is switched off, the coolant temperature value
switches to safe mode, 10°C < PR064 Coolant Temperature < 90°C.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the connection and condition of the coolant temperature sensor connector, component code244 (see
MR 392, 385, 364, 370 and 417, Mechanical, 19A, Cooling system, Coolant temperature sensor:
Removal - Refitting) and the injection computer, component code120 (see MR 392, 385, 364, 370 and 417,
Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Measure the resistance of the coolant temperature sensor, component code 244, between connections 3C and
3JK.

11332Ω < X < 13588Ω at - 10°C,
2140Ω < X < 2364Ω at 25°C,
771Ω < X < 849Ω at 50°C,
275Ω < X < 291Ω at 80°C,
replace the coolant temperature sensor (see MR 392, 385, 364, 370 and 417, Mechanical, 19A, Cooling
system, Coolant temperature sensor: Removal - Refitting).
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3C between components 244 and 120.
–3JK between components 244 and 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
