8.13CRANK POSITION SENSOR (CKP)
GENERAL
The crank position sensor is a variable reluctance (VR) sensor
that generates an AC signal by sensing the passing of the 30
teeth machined in the left side flywheel.Two consecutive teeth
are missing in the flywheel to establish a reference point. The
crank position sensor sends a signal to the ignition control
module which is used to reference engine position (TDC) and
engine speed.
NOTE
CKP sensor connector is not serviceable. If connector or sensor
fails, the entire assembly must be replaced.
