Jetta L4-2.0L (BEV) (2004)
-
Measure resistance at Engine Coolant Temperature (ECT) sensor -G62-, terminals C (signal) and D (Ground (GND)).
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 kilo Ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor -G62- with Engine Coolant Temperature (ECT) sensor -G2-.
WARNING:
-
The cooling system is under pressure.
-
Danger of scalding when opening.
-
Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. See: Powertrain Management/Computers
and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/With Generic Scan Tool/Diagnostic Mode 4: Reset/Erase
Diagnostic Data
-
Generate readiness code. See: Powertrain Management/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-.
