Inspection Procedures

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.

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.

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.

Is voltage within specification? 

Yes: Go to next

No: Repair open in harness.

1. Turn ignition switch to OFF position and disconnect the ECM connector.
2. Measure resistance between terminal 2 of the CCV harness connector and terminal 79 of the ECM harness connector.
