Jetta GLS L4-1.8L Turbo (AWP) (2002)
-
Perform resistance measurement on Intake Air Temperature (IAT) sensor -2- (G42).
-
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 Ohm
If the specification is not obtained:
-
Replace Intake Air Temperature (IAT) sensor (G42).
-
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 Manufacture Scan Tool/Check DTC Memory (Function 02)" See: Testing and Inspection
-
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 "Displaying and Reading Trouble Codes/With Manufacture Scan Tool/Check DTC Memory (Function 02)" See:
Testing and Inspection
Engine code AWW, Refer to "Monitors, Trips and/or Drive Cycle/Generating Readiness Code" See: Testing and Inspection
Engine code AWP, Refer to "Monitors, Trips and/or Drive Cycle/Generating Readiness Code" See: Testing and Inspection
If there is no fault in the wiring and the resistance measurement values are OK.:
-
Replace engine control module.
