Passat Syncro Wagon V6-2.8L (ATQ) (2000)
-
Measure resistance at Engine Coolant Temperature (ECT) Sensor - G62-, terminals C (signal) and D (Ground -GND-).
Continuation for all vehicles
Range A displays resistance values for the temperature range of 0 to 50 degrees C, range B displays resistance values for the temperature range of 50 to
100 degrees C.
Read-out examples:
-
30 degrees C is in range A and corresponds to a resistance of 1.5 to 2.0 kOhms
-
80 degrees C is in range B and corresponds to a resistance of 275 to 375 kOhms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor -G62- with Engine Coolant Temperature (ECT) Sensor -G2-, item 33 .
-
Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data.
-
Generate readiness code. See: Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
If no malfunctions are detected in the wires and the resistance values are OK:
-
Replace Motronic Engine Control Module (ECM) -J220-.
