Crankshaft Position Sensor: Description and Operation

2001 Mazda 626 ES V6-2.5L DOHCSECTION Description and Operation



- The magnetic pickup type crankshaft position sensor is located near the crankshaft pulley.
- The crankshaft pulley has a total of 35 teeth spaced 10 degrees apart with one empty space for a missing tooth.
- The crankshaft position sensor detects the pulley rotation signal (NE signal), and outputs it to the PCM.
- Since the NE signal is detected directly by the crankshaft rotation, accuracy is high and is not influenced by timing belt looseness or camshaft pulley misalignment.
