Services Performed
- Connected a scan tool and found code P1450 – Unable To Bleed Up Fuel Tank Vacuum. Off idle, used the scan tool to monitor live data and found the fuel tank pressure sensor signal parameter was below specifications. Key on, engine off, removed the gas cap and observed the fuel tank pressure sensor signal parameter was low. Connected a smoke machine to the evaporative emission (EVAP) system, induced smoke into the system and found smoke leaked from the EVAP vent, indicating an open vent valve. Used the scan tool to command the EVAP vent solenoid closed and observed the smoke stopped flowing from the EVAP valve, indicating a functional EVAP vent solenoid. Used the smoke machine to perform an EVAP system pressure check and observed the system was unable to hold pressure. Performed a visual inspection of the EVAP system but was unable to locate an external leak. Removed the EVAP purge valve hose from the intake manifold and observed smoke coming from the EVAP purge valve. Visually inspected the EVAP purge solenoid valve and wiring harness, but found no obvious faults. Connected a test light in place of the EVAP purge solenoid valve, used the scan tool to command the EVAP purge solenoid valve open and found the test light was illuminated only when the EVAP purge solenoid valve was commanded open, indicating the wiring and control circuit were functional. Connected a vacuum pump to the EVAP purge solenoid valve and attempted to apply vacuum while the scan tool was used to command the EVAP purge solenoid valve closed. Found the EVAP purge solenoid valve leaked and did not hold the applied vacuum while the valve was commanded closed. – Customer acknowledged notice and gave oral approval of estimated repairs.
