FUEL SYSTEM BLOCKAGE DETECTION AND BLOCKAGE LOCATION IDENTIFICATION SYSTEMS AND METHODS |
摘要 |
A system for a vehicle includes a first pressure module and a blockage indication module. The first pressure module receives a signal from a pressure sensor that measures pressure within a fuel vapor purge system. The first pressure module generates a first pressure based on the signal at a first time and generates a second pressure based on the signal at a second time. The second time is after the first time. The blockage indication module indicates whether a blockage is present in the fuel vapor purge system between the pressure sensor and a fuel tank based on a difference between the first and second pressures.
