Golf GLS L4-2.0L (AEG) (2001)
Range A displays resistance values for the temperature range of 0 to 50°C, range B displays resistance values for the temperature range of 50 to 100°C.
Read-out examples:
30°C is in range A and corresponds to a resistance of 1.5 to 2.0 k ohms
80°C is in range B and corresponds to a resistance of 275 to 375 ohms
If specified value is not obtained:
-
Replace Engine Coolant Temperature (ECT) Sensor -G62- with Engine Coolant Temperature (ECT) Sensor -G2-, item 13 .
-
Erase DTC memory of Engine Control Module (ECM),Diagnostic mode 4: Reset/erase diagnostic data.
-
Generate readiness code. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles
