■ PCV(Positive Crankcase Ventilation) valve check

IG KEY "OFF".

Disconnect PCV valve.

Check the movement of plunger by putting in and out a thin stick.

Is the movement of plunger normal?

	▶ Go to "Injector check" procedure.
	▶ Substitute with a known - good PCV valve and check for proper operation. If the problem is corrected, replace PCV valve and go to "Verification of Vehicle Repair" procedure.

■ Injector check

IG KEY "OFF".

Disconnect injectors.

Check clog on injectors.

Measure the resistance between power and control terminal of injectors(Component side).

Specification :

Is the measured resistance within specifications ?

	▶ Go to "Sensors related to air/fuel ratio check" procedure.
	▶ Repair or replace as necessary. And then, go to "Verification of Vehicle Repair" procedure.

■ Sensors related to air/fuel ratio check

10.

Check the output data of sensors related to air/fuel ratio (HO2S, MAPS, TPS, ECTS, PCSV, Injectors, etc) on GDS. (Refer to each DTC guide procedure.)

11.

Are those sensors normal?

	▶ Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. So, check poor connections and the related circuit between ECM and component thoroughly. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Repair or replace as necessary. And then, go to "Verification of Vehicle Repair" procedure.
