摘要: A method for verifying the reliable operation of a fuel tank pressure transducer positioned within PHEV. The detects initiation refueling cycle, which leads to opening system vent valve between carbon canister and vent, isolation valve. controller monitors at valve, that device determines rates change outlet vent. Reliable is indicated upon determination in are uniform predetermined range.
