Inspection Procedures

  1. CHECK PCSV AND ECM CONNECTORS
    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.

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