Camshaft Position Sensor


A Hall Effect Switch positioned in the distributor housing, serves as a cam position sensor for the sequential port fuel injection system. The Hall Effect senses the opening point of the intake valve on the number one cylinder and provides that information to the Powertrain Control Module (PCM). Fuel injection is sequenced relative to the engine firing order once No. 1 intake stroke is determined.
