TEST ACTION APPLICABILITY 2 Perform a visual and physical inspection of the entire Evaporative Emission system. All Yes → Repair as necessary. Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC. No → Go To 3 3 Turn the ignition off. All Yes → Repair the vacuum supply, hose/tube as necessary. Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC. No → Go To 4 4 Disconnect the vacuum supply hoses form the EVAP Purge Solenoid. 9CAN9 side of the EVAP Purge Solenoid. t, actuate the EVAP Purge Solenoid . Does the vacuum drop when the solenoid is actuated? All Yes → Go To 5 No → Replace the Evap Purge Solenoid. Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC. 5 NOTE: The fuel level must be below 85%, or the Onboard Refueling Vapor ( in Hg the switch should close. Using a manometer (Miller #6872A) connected to the service port can aid in properly reading the t. Do not exceed 2 9 in Hg while performing this step. NOTE: The NVLD Switch reads normally open. When the vacuum is applied ( in Hg is reached the switch state should be in the closed position. Once the vacuum has been released the Switch state should return to the All Yes → Refer to the INTERMITTENT CONDITION symptom in the Driveability category. No → Go To 6 351 DRIVEABILITY - NGC P0440-GENERAL EVAP SYSTEM FAILURE — Continued |
