Passat Wagon 4Motion V6-2.8L (ATQ) (2003)
-
Check wires between test box and 2-pin connector for open circuit according to wiring diagram.
Terminal 1 + socket 85
Terminal 2 + socket 108
Wire resistance: max: 1.5 Ohms
Continuation for all vehicles
-
Also check wires for short circuits to each other, to vehicle Ground (GND) and to B+.
Specified value: Infinity Ohms
If no malfunctions are found in wire:
-
Measure resistance at Intake Air Temperature (IAT) Sensor -G42-.
Range A displays resistance values for the temperature range of 0 to 50 degrees C, range B displays resistance values for the temperature range of 50 to
100 degrees C.
Read-out examples:
-
30 degrees C is in range A and corresponds to a resistance of 1.5 to 2.0 kOhms
-
80 degrees C is in range B and corresponds to a resistance of 275 to 375 KOhms
If specified value is not obtained:
-
Replace Intake Air Temperature (IAT) Sensor -G42-, item 10 .
-
Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data.
-
Generate readiness code. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles
and Readiness Codes
