KB1 - Check CANP Valve Electrical Operation
Diagnostic Trouble Code (DTC) 565 indicates Canister Purge (CANP) valve failure has been detected.Possible causes:
- Damaged CANP valve.
- Damaged vacuum hose to CANP valve from manifold.
- Open in VPWR harness circuit.
- Open in solenoid control signal circuit.
- Short to power in solenoid control signal circuit.
- Short to ground in solenoid control signal circuit.
- Damaged Powertrain Control Module (PCM).
- Key "OFF".
- Key "ON", engine "OFF".
- Disconnect Canister Purge 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 KB2. KB2 - Check CANP Valve Resistance
No -- Remove jumper. Go to KB6. KB6 - Check VPWR Circuit Voltage
