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:
