Inspection Procedures

CHECK CCV FOR CONNECTOR CONDITION
1. Thoroughly check the CCV for loose, bent, corroded, contaminated, deteriorated or damaged connectors.
  Is any problem present?
No: Go to next

Yes: Repair or replace it.
CHECK CCV RESISTANCE
1. Turn ignition switch to OFF position and disconnect the CCV harness connector.
2. Measure resistance between terminals 1 and 2 of the CCV connector

- ^*Specification: 23~26ohm at 20°C (68°F)
  Is resistance within specification?
Yes: Go to next

No: Replace it.
CHECK POWER TO CCV
1. Turn ignition switch to OFF position.
2. Turn ignition switch to ON position and measure the voltage between terminal 1 of the CCV harness connector and chassis ground.

- Specification: approximately B+
  Is voltage within specification?
Yes: Go to next

No: Repair short to chassis ground in harness.
CHECK FOR SHORT TO GROUND IN HARNESS
1. Turn ignition switch to OFF position.
2. Measure resistance between terminal 2 of the CCV harness connector and chassis ground.
3. Measure resistance between terminals 1 and 2 of the CCV harness connector.

- Specification: infinite
  Does each resistance indicate open?
Yes: Go to next

No: Repair short to chassis ground in harness.
CHECK FOR SHORT TO POWER IN HARNESS
1. Turn ignition switch to ON position.
2. Measure voltage between terminal 2 of the CCV harness connector and chassis ground.
