-
If the engine shows problems in certain temperature ranges and if the temperature does not climb uniformly, the temperature signal is intermittent
and the sensor should be replaced.
-
End diagnosis and switch ignition off.
If indications do not resemble description:
Checking internal resistance
-
Disconnect harness connector -4- at Engine Coolant Temperature (ECT) Sensor -G2-/-G62-.
NOTE: Disregard the other items.
-
Connect multimeter between terminal C and D of sensor for resistance measurement.
Range A displays resistance values for the temperature range of 0...50 degree C, range B displays resistance values for the temperature range of 50...100
degree C.
Read-out examples:
-
30 degree C corresponds to a resistance of 1500 to 2000 Ohms
-
80 degree C corresponds to a resistance of 275 to 375 Ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor (G62).
If specified value is obtained:
