Canister Purge Valve
- With engine at normal operating temperature, disconnect purge hose from top of canister. With engine idling, vacuum should not be present. As engine speed increases to more than 1500 RPM, vacuum should be present. If vacuum is not as specified, check vacuum passage, hoses, solenoid valve, wiring harness or ECM for defects. Repair or replace as necessary.
- Place finger over nozzle to check for vacuum. If necessary, clean blocked nozzle with compressed air. Check hoses for proper connection, leaks, clogging and/or deterioration. Replace as necessary.
