-
Check resistance of fuel injectors between terminals.
Specified value: 13.0-19.0 ohms
NOTE: The resistance figures are valid for approx. 20 °C. At higher temperatures the resistance figures will increase.
If the specified value is not obtained:
-
Replace faulty fuel injector, item 12. Refer to "Intake Manifold Lower Section, Disassembling and Assembling",
Pay attention to the following when installing the fuel injector:
-
Replace O-rings on all fuel injectors and lightly moisten with clean engine oil.
-
Insert fuel injectors vertically and in the correct position into the fuel rail and secure using retaining clips.
-
Fit fuel rail with fuel injectors installed and secured on intake manifold lower section and press in evenly.
-
Check DTC memory. If necessary, repair any malfunctions and erase DTC memory2.
-
Display readiness code.
If DTC memory has been erased or the Engine Control Module (ECM) was disconnected from permanent battery (B+) voltage, the readiness code
must be generated again.
Checking voltage supply
-
Connect voltage tester to terminal -1- and Ground of relevant fuel injector harness connector.
-
Operate starter and check voltage supply for fuel injector.
The LED must light up.
If the LED does not light up:
-
Switch ignition off.
-
Check wire between 2-pin harness connector terminal -1- and Fuel Pump (FP) relay -J17- for open circuit according to wiring diagram.
Wire resistance: max. 1.5 ohms
