(4) Is the measured resistance within specifications?

YES
> Go to " Check for open in harness" as below.
NO
> Check short to ground in signal harness.
> Repair or replace as necessary and then, go to " Verification of Vehicle Repair" procedure.

2. Check for open in harness.

(1) Ignition "OFF"
(2) Disconnect CCV and PCM connector
(3) Measure resistance between terminal "2" of CCV harness connector and terminal "37" of PCM harness connector.

Specification : Approx. below 1Ohms

3. Is the measured resistance within specifications?

YES
> Go to " Component Inspection " procedure.
NO
> Check open in harness between CCV connector and PCM connector.
> Repair or replace as necessary and then, go to " Verification of Vehicle Repair" procedure.

COMPONENT INSPECTION

1. Check CCV

(1) Ignition "OFF"
(2) Measure resistance between terminals "1" and "2" of the CCV connector.

Specification: Approx. 19.8 -21.8Ohms(20°C(68°F))

(3) Monitor the CCV signal waveform and verify that the ground voltage is less than approx. 0.3V (1) and the surge voltage (2) is between 40 V

and 60 V.
