TDC/CRANK/CYL Sensor
TDC/CRANK/CYL sensor is a combination sensor located inside distributor. Each sensor generates a separate signal. CRANK 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. CYL sensor detects position of No. 1 cylinder for sequential fuel injection to each cylinder.
