Control Circuit Inspection

Check for open in harness
1. Ignition "OFF"
2. Disconnect PCSV sensor connector.
3. Ignition "ON" & Engine "OFF"
4. Measure voltage between terminal 2 of PCSV harness connector and chassis ground.
  Specification: approximately 3.7V

5. Is measure voltage within Specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Open circuit between PCSV harness connector and PCM harness connector.
  - Short circuit to chassis ground between PCSV harness connector and PCM harness connector.
  - Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE:
  In case the measured voltage is 0V when checking control line
  - Possible cause: If the measured voltage indicates 0V, the problem is that control line is open, so check the open circuit between terminal 46 of PCM and terminal 2 of PCSV
