Tiguan 4Motion (5N1) L4-2.0L Turbo (CCTA) (2009)
electrical harness connector T60 terminals for an open or short to ground circuit.
Specified values: 1.5 ohms max. for wire continuity, and for circuit to ground check; Infinite or "OL" should be displayed
If the specified value was Not obtained:
-
Check the wiring for an open, high resistance or short to ground.
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If voltage is within specification:
Checking internal resistance
-
Using a multimeter, check the Fuel Injector electrical terminals (1 to 2 for N30, 3 to 4 for N31, 5 to 6 for N32 or 7 to 8 for N33 ) for resistance.
Specified value: 1.4 - 2.6 ohms (at approx. 20 °C)
If the specified value was Not obtained:
-
Replace the malfunctioning Fuel injector(s). Refer to the Repair Information.
If the specified value was obtained:
Checking activation and wiring
-
Connect a Diode test lamp (12 V) from Battery + to the injector harness connector terminal (1 for N30, 3 for N31, 5 for N32 or 7 for N33 ) of the
Fuel Injector to be tested.
-
Operate the starter and test the activation of the Fuel Injector.
LED should flicker.
-
Switch the ignition off.
If LED does not flicker:
If the manufacturers test box is being used, perform the following step.
-
Install the test box.
If the manufacturers test box is not being used, perform the following step.
-
Remove the Motronic Engine Control Module (ECM) ( J623). Refer to the Repair Information.
-
Using a multimeter, check the Fuel Injector electrical harness connector terminals to the Motronic Engine Control Module (ECM) (J623) electrical
harness connector T60 terminals for an open circuit.
