Car high pressure engine fuel supply pressure sensor signal voltage sensing system switch between earth, supply and signal potentials and calculates signal voltage

摘要

A car high pressure engine fuel supply pressure sensor (4) signal voltage sensing system uses (1) a switch (5) and voltage divider (VD) to measure (2) periodically the earth (V0), supply (V1) and signal (V2) voltage dependent signal potentials at the sensor signal output and calculates the signal voltage. Includes an INDEPENDENT CLAIM for a controller with implementation of the system as a computer program store in Flash or ROM (Read Only Memory) memory.
