Crankshaft Position Sensor: Description and Operation
The CRANK Sensor determines timing for fuel injection and ignition of each cylinder and also detects engine rpm. The TDC sensor determines
ignition timing at start-up (cranking) and when crank angle signal is abnormal. The CYL sensor detects the position of No. 1 cylinder for
sequential fuel injection to each cylinder.
