The temperature value must increase uniformly in increments of 1.0 degrees C.
If the engine shows problems in certain temperature ranges and if the temperature does not climb uniformly, the temperature signal is intermittent.
-
Replace the the Engine Coolant Temperature (ECT) Sensor G62 Engine Mechanical, Fuel Injection Ignition.
Checking internal resistance
-
Disconnect the Engine Coolant Temperature (ECT) Sensor G62 electrical harness connector - 1 -.
-
Using a multimeter, check the Engine Coolant Temperature (ECT) Sensor G62 terminals 1 to 2 for resistance.
Use the chart below for the specified values:
-
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 k Ohms
-
Range B, 80 degrees C equals a resistance of 275 to 375 Ohms
If any of the specified values was not obtained:
-
Replace the the Engine Coolant Temperature (ECT) Sensor G62 Engine Mechanical, Fuel Injection Ignition.
Testing if display is approx. - 40.0 degrees C:
