Component Inspection

PCV (Positive Crankcase Ventilation) valve check.
1. Key "OFF".
2. Disconnect PCV valve.
3. Check PCV plunger movement.
4. Is the movement of plunger normal?
  YES : --> Go to "PCSV check" procedure.
  
  NO : --> 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.
PCSV check.
1. Key "OFF".
2. Disconnect PCSV and vacuum hose.
3. Apply a vacuum by a hand vacuum gauge on PCSV.
4. Does PCSV keep the vacuum condition normally?
  YES : --> Go to "Injector check" procedure.
  
  NO : --> Substitute with a known - good PCSV and check for proper operation.
  
  --> If the problem is corrected, replace PCSV and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Injector check.

Key "OFF".
Disconnect injectors.
Check clog on injectors.

Measure the resistance between terminal 1 and 2 of injectors (Component side).

INJECTOR SPECIFICATION

Temperature	Resistance (Ω)
20°C (68°F)	13.8 ~ 15.2Ω

Fig 1: Measuring Resistance Between Terminal 1 And 2 Of Injectors

G04801663

Is the measured resistance within specifications?
YES : --> Go to "Sensors related to air/fuel ratio check" procedure.

NO : --> Repair or replace as necessary. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Sensors related to air/fuel ratio check.
1. Check the output data of sensors related to air/fuel ratio (HO2S, MAPS, TPS, ECTS, PCSV, Injectors, etc.) on scantool. (Refer to each DTC guide procedure.)
2. Are those sensors normal?
  YES : --> Substitute with a known - good ECM/PCM and check for proper operation.
  
  NO : --> If the problem is corrected, replace ECM/PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  
  --> Repair or replace as necessary. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
