Passat Sedan V6-3.6L (BLV) (2008)
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:
