CC.0: Short circuit to earth
CO.1: Open circuit or short circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present during engine starting attempts or while the engine is
running.
Special notes:
If the fault is present:
– the coolant temperature: PR064 Coolant temperature is fixed at 11 9 ° C,
– the preheating phase is greater than 10 seconds,
– the low speed motor-driven fan assembly (GMV 1) is continuously supplied,
–if fan assembly 1 is faulty, then fan assembly 2 is activated on vehicles equipped
with air conditioning,
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (start the
engine
+ 5 seconds, then switch off the ignition and wait for 1 minute).
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
Check the coolant temperature sensor connections.
Check the injection computer connections.
Repair if necessary.
Measure the resistance of the coolant temperature sensor between connections 3C and 3JK.
Replace the sensor if its resistance is not approximately:
68780 Ω < X < 82780 Ω at - 40°C
12338 Ω < X < 12582 Ω at - 10°C
2140 Ω < X < 2364 Ω at 25°C
772 Ω < X < 850 Ω at 50°C
275 Ω < X < 291 Ω at 80°C
11 2 Ω < X < 118 Ω at 110°C
85 Ω < X < 89 Ω at 120°C
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code3C,
– connection code 3JK,
between components 120 and 244.
If the connection or connections 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, replace the coolant temperature sensor.
AFTER REPAIRDeal with any faults.
