PRESENT
OR
STOREDCOOLANT TEMPERATURE SENSOR CIRCUIT
CC.0 : Short circuit to earth
CO.1 : Short circuit or open circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present:
–when an attempt is made to start the engine,
–when the engine is running.
Special notes:
If the fault is present:
–the coolant temperature: PR064 Coolant temperature is fixed at 119˚C,
–the preheating phase is greater than 10 seconds,
–the low speed motor-driven fan assembly (GMV 1) is continuously supplied,
–if there is a fault with GMV 1, then start GMV 2 for vehicles with air conditioning.
–the level 1 warning light is lit,
–the OBD warning light will illuminate after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
Check the connections of the coolant temperature sensor 4-track connector.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the coolant temperature sensor between tracks 2 and 3 of its black connector.
Replace the sensor if its resistance is not approximately:
75780 ± 7000 Ω at - 40˚C
12460 ± 122 Ω at - 10˚C
2252 ± 112 Ω at 25˚C
811 ± 39 Ω at 50˚C
283 ± 8 Ω at 80˚C
115 ± 3 Ω at 110˚C
87 ± 2 Ω at 120˚C
Check the insulation, continuity and the absence of interference resistance on the following connections:
Injection computer brown 48-track connector B
track F2Track 3 coolant temperature sensor
Injection computer brown 48-track connector B
track H1Track 2 coolant temperature sensor
Repair if necessary.
If the fault is still present, replace the coolant temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
