Camshaft Position Sensor (2.5L)
Camshaft Position (CMP) sensor is located in the distributor on right side of engine. The CMP sensor is made up of a Hall Effect switch (sync signal generator) and a rotating pulse ring (shutter) on the distributor shaft. See Distributor (Wrangler 2.5L) under IGNITION SYSTEMS. The pulse ring rotates 180 degrees through the sync signal generator. Signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. CMP sensor signal is also used to synchronize fuel injectors with their respective cylinders.
