New Beetle Turbo S L4-1.8L Turbo (AWP) (2002)
-
terminal 3 + vehicle Ground (GND)
Specification: Infinity Ohms
-
Additionally check both wires for short to battery positive.
Specification: Infinity Ohms
If no wiring malfunctions are detected:
-
Perform resistance measurement on Engine Coolant Temperature (ECT) sensor -G62- terminal C (signal) and D (Ground).
-
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 kOhms
-
80 °C is in range B and corresponds to a resistance of 275 to 375 Ohms
If the specification is not obtained:
-
Replace Engine Coolant Temperature (ECT) sensor -G62- with Engine Coolant Temperature (ECT) sensor -G2-, item 28.
-
Check DTC Memory, if necessary, repair any malfunctions and then Erase DTC Memory, Checking and Erasing DTC Memory. See: Powertrain
Management/Computers and Control Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Reading Diagnostic
Trouble Codes
-
Read readiness code. If DTC memory has been erased or Motronic Engine Control Module (ECM) -J220- was disconnected from battery positive,
readiness code must be generated again.

See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
If there is no malfunction in the wiring and the resistance measurement values are OK:
-
Replace Motronic Engine Control Module (ECM) -J220-.
