Golf L4-1.9L DSL Turbo (BEW) (2004)
-
Disconnect connector at coolant temperature sensor.
-
Measure resistance between terminals 3 + 4 on sensor.
Continuation for all vehicles
See diagram for specified value.
Range A displays resistance values for the temperature range of 0...50 degree C, range B displays resistance values for the temperature range of 50...100
degree C.
Read-out examples:
Continuation for all vehicles
30° C corresponds to a resistance of 1500 to 2000 Ohm
80° C corresponds to a resistance of 275 to 375 Ohm
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor -G62- with Engine Coolant Temperature (ECT) Sensor -G2-.
-
Erase DTC memory of control module for Diesel- Direct fuel injection system, Diagnostic mode 4: Reset/erase diagnostic data. See: Powertrain
Management/Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode, Selecting/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 Diesel Direct Fuel Injection (DFI) Engine Control Module (ECM) -J248-
