Sensors are simple electronic devices that detect and convert a change in pressure, temperature, or mechanical movement into an electrical signal

Pressure Sensors measure changes in pressure and send a variable DC voltage to the ECMThey have 3 wiresfrom 0.5 Vto 4.5 V 0 V reference5 V +/- 0.5 V

This sensor gives the speed , rotation and crankshaft position to the ECM
