Component Inspection

■ Check PCV 

1. IG "OFF".
2. Disconnect PCV.
3. Check that PCV is properly operating.
4. Is the PCV O.K?

   YES 

   • Go to "Check PCSV" as follows.

   NO 

   • Substitute with a known - good PCV and check for proper operation.

     If the problem is corrected, replace PCV and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check the PCSV 

1. Ignition "OFF".
2. Disconnect PCSV and Vacuum Hose.
3. Apply vacuum on PCSV with Hand Vacuum Gauge.
4. Is the PCSV keeping the Vacuum?

   YES 

   • Go to "Check Injector"procedure below.

   NO 

   • Substitute with a known-good PCSV and check for proper operation.

     If the problem is corrected, replace PCSV and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check Injector 

1. Ignition "OFF".
2. Remove Injector.
3. Check Leakage and clog on Injector.
4. Measure resistance terminal 1 and 2 of Injector connector (Component side).

   Specification: 

   Coil Resistance (Ω)	Temp (°C)	Temp (°F)
   1.25	20	68

5. Is the measured resistance within specifications?

   YES 

   • Go to "Check sensors related to Fuel Trim" procedure below.

   NO 

   • Substitute with a known-good Injector and check for proper operation.

     If the problem is corrected, replace Injector and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check Sensors related to Fuel Trim 

1. Check the Input Voltage of Sensors related to Fuel Trim (MAPS, TPS, ECTS, PCSV, Injector, and etc)
2. Are the sensors related to Fuel Trim O.K?

   YES 

   • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
