It cost $170 to diagnose and the estimate is an add'l $300 to repair. Estimate states "Found P0456 - Evap emission control system, very small leak detected. Performed smoke test on system, no external leaks. Placed a vacuum pump on the purge valve, found unit is not holding vacuum, indicating it has failed internally. Recommend replacement of unit."

Thank you!
