The vacuum pump includes a cam ring, a rotor that rotates within the cam ring, and vanes that slide into and out of slots in the rotor as the rotor rotates. The pump control module switches on the vacuum pump for a predetermined period to force the vanes out of the slots and into contact with the cam ring to seal the vacuum pump before switching off the vacuum pump for the fuel system diagnostic test. | 04-17-2014 |
20140260575 | SYSTEM AND METHOD FOR DIAGNOSING FLOW THROUGH A PURGE VALVE BASED ON A FUEL SYSTEM PRESSURE SENSOR - A system according to the principles of the present disclosure includes a pressure sensor, a pressure variation module, and a purge flow diagnostic module. The pressure sensor generates a pressure signal indicating a pressure within a fuel system of an engine. The pressure variation module determines an amount of variation in the pressure signal over a period. The purge flow diagnostic module diagnoses a fault associated with flow through a purge valve of the fuel system when the pressure variation amount is less than a threshold. | 09-18-2014 |
20140352658 | SYSTEM AND METHOD TO DIAGNOSE FUEL SYSTEM PRESSURE SENSOR - A system includes an ignition detection module, a pressure sensor, a pressure variation module, and a pressure sensor diagnostic module. The ignition detection module detects when an engine is started. The pressure sensor generates a first pressure signal indicating a first pressure within a fuel system of the engine when the engine is started and when a purge valve of the fuel system is closed. The pressure variation module determines an amount of variation in the first pressure signal over a first period. The pressure sensor diagnostic module determines a state of the pressure sensor based on the amount of variation in the first pressure signal over the first period. | 12-04-2014 |
