Nissan Rogue Service Manual: Fuel injector
Component Function Check
1.INSPECTION START
Turn ignition switch to START.
Are any cylinders ignited? YES >> GO TO 2.
NO >> Proceed to EC-464, "Diagnosis Procedure".
2.CHECK FUEL INJECTOR FUNCTION
With CONSULT
- Start engine.
- Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT.
- Check that each circuit produces a momentary engine speed drop.
Without CONSULT
- Start engine.
- Listen to each fuel injector operating sound.
Clicking sound should be heard.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-464, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK FUEL INJECTOR POWER SUPPLY
- Turn ignition switch OFF.
- Disconnect fuel injector harness connector.
- Turn ignition switch ON.
- Check the voltage between fuel injector harness connector and ground
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect IPDM E/R harness connector.
- Check the continuity between fuel injector harness connector and IPDM E/R harness connector.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK FUEL INJECTOR OUTPUT SIGNAL CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between fuel injector harness connector and ECM harness connector.
Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.
4.CHECK FUEL INJECTOR
Check fuel injector. Refer to EC-465, "Component Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace malfunctioning fuel injector. Refer to EM-40, "Exploded View".
5.CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to GI-41, "Intermittent Incident".
Is the inspection result normal? YES >> Replace IPDM E/R. Refer to PCS-35, "Removal and Installation".
NO >> Repair or replace error-detected parts.
Component Inspection
1.CHECK FUEL INJECTOR
- Turn ignition switch OFF.
- Disconnect fuel injector harness connector.
- Check resistance between fuel injector terminals as per the following.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace malfunctioning fuel injector. Refer to EM-40, "Removal and Installation".
