Crankshaft Position Sensor #1

Crankshaft Position Sensor:

PURPOSE
The Crankshaft Position Sensor No.1 (CKP1) determines engine speed for fuel injection timing, ignition timing, and emission control.

OPERATION
A six-vane rotor is mounted to the distributor shaft and rotates at camshaft speed. As the rotor passes through a magnetic Hall Effect pickup switch, the sensor creates six evenly (60° intervals) spaced signals for each distributor rotation. vanes are detected and sent to the Powertrain Control Module (PCM) in a pulse wave form.
