A vapor purge system having a tank isolation valve and a canister vent valve, where each valve includes a latching mechanism for maintaining the valves in an open position, and a diagnostic test is performed on the purge system to prove that each of the valves are functioning correctly. Using latching valves in these applications reduces electricity draw from the battery and reduces electrical interference with integrated pressure sensors. The fuel tank is sealed by the tank isolation valve between the fuel tank and a vapor storage canister, and the canister vent valve provides sealing between the canister and the atmosphere, and controls venting of the canister. The diagnostic test is performed using the tank isolation valve and the canister vent valve under different operating conditions.
An apparatus, comprising:
A valve assembly which is part of a vapor purge system, comprising:
A valve assembly having an integrated pressure sensor device, comprising:
