Check for short to ground in control circuit.
1. Ignition "OFF".
2. Disconnect PCM connector.
3. Measure resistance between terminals 2 of the CCV harness connector and 79 of the PCM harness connector.
  Specification: Approx. 0ohm
4. Is resistance within the specification?
  YES:
  - Go to next step below.
  NO:
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for short to battery in control circuit
1. Ignition "ON" & Engine "OFF"
2. Measure voltage between terminal 2 of the CCV harness connector and chassis ground
  Specification: Approx. 0V
3. Is voltage within the specification?
  YES:
  - Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
  NO:
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
