-
Connect multimeter between terminal 3 and 4 of sensor for resistance measurement.
Continuation for all vehicles
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 Ohm
-
80 degree C corresponds to a resistance of 275 to 375 Ohm
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor -G62- with Engine Coolant Temperature (ECT) Sensor -G2-.
-
Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. See: Powertrain Management/Computers
