-
Also check wires for short circuit to each other, to vehicle Ground (GND) and to B+.
Specified value: infinite Ohm
If no malfunctions are found in wire:
Vehicles with engine code AFP
-
Measure resistance at Intake Air Temperature (IAT) Sensor -G42-, terminals 1 (signal) and 3 (Ground -GND-).
Vehicles with engine code BDF
-
Measure resistance at Intake Air Temperature (IAT) Sensor -G42-, terminals 1 (signal) and 3 (Ground -GND-).
Continuation for all vehicles
Range A displays resistance values for the temperature range of 0...50 degree C, range B displays resistance values for the temperature range of 50...100
degee C.
Read-out examples:
-
30 degree C is in range A and corresponds to a resistance of 1.5 to 2.0 kOhms
-
80 degree C is in range B and corresponds to a resistance of 275 to 375 Ohm
If specified value is not obtained:
-
Replace Mass Air Flow (MAF) Sensor -G70-:
