1. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Are all connectors good? 

Yes: Go to next

No: Repair or replace it.

1. Turn ignition switch to OFF position and disconnect PCSV harness connector.
2. Measure resistance between terminals 1 and 2 of the PCSV.

• Refer to  SPECIFICATIONS  
• Refer to  EVAPORATIVE (EVAP) CANISTER PURGE SOLENOID VALVE  of Evaporative emission control system. 

Is the PCSV normal? 

Yes: Go to next

No: Replace it.

1. Turn ignition switch to ON position.
2. Measure voltage between terminal 1 of the PCSV harness connector and chassis ground.

• Specification: approximately B+ 

Is voltage within specification? 

Yes: Go to next

No: Repair open or short to chassis ground in harness.

1. Turn ignition switch to OFF position and disconnect the ECM connector.
2. Measure resistance between terminal 2 of the PCSV harness connector and 26 of the ECM harness connector.
