- Key "ON", engine "OFF".
- Disconnect Canister Purge (CANP) valve.
- Connect Analog Volt/Ohm Meter (VOM)/Digital Volt/Ohm Meter (DVOM) positive test lead to VPWR circuit and negative test lead to CANP circuit at the CANP valve vehicle harness connector.
- DVOM on 20 volt scale.
- While observing VOM/DVOM depress and release the throttle several times to cycle output.
- Does CANP circuit cycle 0.5 volt or greater?
Yes -- Remain in Output State test mode. Go to KB3. KB3 - Check CANP Valve Resistance
No -- Remove jumper. Go to KB7. KB7 - Check VPWR Circuit Voltage
