Golf L4-1.8L Turbo (AWD) (2000)
-
Perform resistance measurement on Intake Air Temperature (IAT) sensor -2- (G42).
Scale A shows resistance values for temperature range 0 - 50 °C and scale B the values for temperature range 50 - 100 °C.
Examples:
-
30 °C is in range A and corresponds to a resistance of 1.5 - 2.0 kohms
-
80 °C is in range B and corresponds to a resistance of 275 - 375 ohms
If the specification is not obtained:
-
Replace Intake Air Temperature (IAT) sensor (G42).
If there is no fault in the wiring and the resistance measurement values are OK.:
-
Replace engine electronics control module.
