If display zone 3 shows an implausible value:
-
Disconnect connector -2- at Engine coolant temperature (ECT) gauge/Engine coolant temperature (ECT) sensor -G2-/-G62-.
-
Connect multimeter between terminals degree C and D of sensor to measure resistance.
Range A shows resistance values for temperature range 0 to 50 degree C and range B shows the values for temperature range 50 to 100 degree C.
Sample readings:
-
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:
