摘要: A system for a vehicle includes a pump control module, an adjustment determination module, and an adjusting module. The pump control module selectively disables pumping of a fuel pump that is driven by a spark ignition direct injection (SIDI) engine. A predetermined period after the pumping of the fuel pump is disabled, the adjustment determination module determines a pressure adjustment for a first fuel rail pressure measured using a fuel rail pressure sensor. The adjusting module generates a second fuel rail pressure based on the pressure adjustment and the first fuel rail pressure.
