New Beetle GL L4-2.0L (AZG) (2002)
-
Perform resistance measurement at intake air temperature sensor(G42) terminals 1 (signal) and 2 (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 k Ohms
-
80 °C is in range B and corresponds to a resistance of 275 to 375 Ohms
If the specification is not obtained:
-
Replace intake air temperature sensor (G42)
-
Check DTC memory, if necessary, repair any malfunctions and then erase DTC memory. See: Testing and Inspection/Reading and Clearing
Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes
-
Read readiness code. If DTC memory has been erased or engine control module was disconnected from permanent positive, readiness code must
be generated again.

If there is no malfunction in the wiring and the resistance measurement values are OK:
-
Replace engine control module.
-
Check DTC memory, if necessary, repair any malfunctions and then erase DTC memory. See: Testing and Inspection/Reading and Clearing
