CRANKSHAFT POSITION (CKP) SENSOR
YAA1F250
This Electronic Ignition (EI) system uses inductive or pickup type magnetic Crankshaft Position (CKP) sensor. The
CKP sensor is located in the opposite side of the crankshaft pulley and triggers the pick-up wheel teeth which is
equipped 60 -- 2 teeth with a gap of 2 teeth at 360 degree spacing. This sensor protrudes through its mount to within 1.1
±0.14 mm.
The output of the sensor is a sinusoidal signal. Each tooth of the pick-up 60 -- 2 wheel generates a positive half wave.
The Engine Control Module (ECM) uses this sensor signal to generate timed ignition and injection pulses that it sends
to the ignition coils and to the fuel injectors.
