Crankshaft Angle Sensor

The crankshaft angle sensor is a Hall Effect magnetic switch. The Hall Effect switch is activated by vanes on the crankshaft damper and pulley assembly. The Profile Ignition Pickup (PIP) is a crankshaft position signal that is sent to the ECA. The PIP signal generated by the Hall Effect sensor provides base timing and RPM information to the ECA .
