If no malfunctions are found in wire:
Checking resistance
-
Measure resistance at Engine Coolant Temperature (ECT) Sensor -G62-, terminals C (signal) and D (Ground GND).
Range A displays resistance values for the temperature range of 0 to 50 degrees C, range B displays resistance values for the temperature range of 50 to
100 degrees C.
Read-out examples:
-
30 degrees C is in range A and corresponds to a resistance of 1.5 to 2.0 kohms
-
80 degrees C is in range B and corresponds to a resistance of 275 to 375 Ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor -G62- with Engine Coolant Temperature (ECT) Sensor -G2-.
WARNING:
-
The cooling system is under pressure.
-
Danger of scalding when opening.
