R32 4Motion V6-3.2L (CBRA) (2008)
-
Area A: Resistance values 0 to 50 degrees C.
-
Area B: Resistance values 50 to 100 degrees C.
Specified values:
-
Range A, 30 degrees C equals a resistance of 1.5 to 2.0 kohms
-
Range B, 80 degrees C equals a resistance of 275 to 375 ohms
If any of the specified values was not obtained:
-
Replace the Engine Coolant Temperature (ECT) Sensor (on Radiator) G83.
If any of the specified values was obtained:
Checking wiring
If the specified value was not obtained:
If the manufacturers test box is being used. Perform the following step.
-
Install the test box.
If the manufacturers test box is not being used. Perform the following step.
-
Remove the Engine Control Module (ECM) J623.
-
Using a Multimeter, check the Engine Coolant Temperature (ECT) Sensor (on Radiator) G83 electrical harness connector terminals to the Engine
Control Module (ECM) J623 electrical harness connector T121 terminals for resistance.
