Crankshaft Position (CKP) Sensor

CKP sensor identifies TDC of No. 3 cylinder. A notch (located at 62 degrees BTDC in counterweight of crankshaft for No. 3 cylinder) is used as the reference point. The notch, along with reference sensor, generates one signal per crankshaft revolution. The signal from reference sensor along with a signal from the CMP sensor are used during starting to identify TDC of No. 3 cylinder ignition point.
