Crankshaft Position/Top Dead Center/Cylinder Position (CKP/TDC/CYP) Sensor

CKP/TDC/CYP sensor is a combination of 3 sensors located inside distributor. Each sensor generates a separate signal. CKP sensor detects engine RPM to determine fuel injection timing and ignition of each cylinder. TDC sensor determines ignition timing at start-up (cranking) and detects when crank angle signal is abnormal. CYP sensor detects position of cylinder No. 1 for sequential fuel injection to each cylinder.
