Signal Circuit Inspection

Check voltage
1. IG "OFF" and disconnect CKPS connector.
2. IG "ON" and ENG "OFF"
3. Measure voltage between terminal 1 of CKPS harness connector and chassis ground.
4. Measure voltage between terminal 2 of CKPS harness connector and chassis ground.
  Specification : Approx. 1.4V
5. Is the measured voltage within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Go to " 2Check open in harness" as follows.
Check open in harness
1. IG "OFF" and disconnect CKPS connector and PCM connector.
2. Measure resistance between terminal 1 of CKPS harness connector and terminal 41 of PCM harness connector.
3. Measure resistance between terminal 2 of CKPS harness connector and terminal 21 of PCM harness connector.
  Specification : Below 1Ω
4. Is the measured resistance within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair open in harness, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
