Abstract
Disclosed herein is a multiple function pressure sensor for use in combination with an electronic fuel injection system for an internal combustion engine. The preferred embodiment has two pressure sensitive elements in a single housing which generate signals indicative of the absolute pressure in the engine's intake manifold and the absolute value of the ambient or atmospheric pressure. Included electronic circuitry subtracts the value of the engine's manifold pressure from the value of the atmospheric pressure and generates a third pressure signal indicative of the difference between the manifold pressure and atmospheric pressure. These three pressure signals are utilized in the electronic fuel injection system for computing the fuel requirements of the engine under various operating conditions.
