Jetta L4-1.8L Turbo (AWP) (2004)
-
Perform resistance measurement on Engine Coolant Temperature (ECT) sensor (G62) contact C (signal) and D (Ground (GND)).
Scale A shows resistance values for temperature range 0 to 50 °C and scale B the values for temperature range 50 to 100 °C.
Examples:
-
30 °C is in range A and corresponds to a resistance of 1.5 to 2.0 kOhm
-
80 °C is in range B and corresponds to a resistance of 275 to 375 kOhm
If the specification is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor (G62).
-
Check DTC Memory, if necessary, repair any malfunctions and then Erase DTC Memory,Checking and Erasing DTC Memory. Refer to
"Displaying and Reading Trouble Codes/With Manufacturer's Scan Tool/Erase DTC Memory (Function 05)" See: Testing and Inspection/Reading
and Clearing Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes/With Manufacturer's Scan Tool/DTC Memory Checking and
Erasing/Erase DTC Memory (Function 05)
-
Read readiness code. If DTC memory has been erased or engine control module was disconnected from permanent positive, readiness code must
be generated again: Refer to ""Monitors, Trips and/or Drive Cycle (Readiness Codes)/With Manufacturer's Scan Tool/Displaying and Creating
Readiness Codes/Readiness Code, Reading" See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
Engine code AWP, Refer to "Monitors, Trips and/or Drive Cycle (Readiness Codes)/With Manufacturer's Scan Tool/Displaying and Creating
Readiness Codes/ Readiness Code, Generating" See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
If there is no fault in the wiring and the resistance measurement values are OK.:
-
Replace engine control module.
