Where Is the Crankshaft Sensor Located?

Crankshaft sensors are located in the crank pulley, flywheel, camshaft or directly on the crankshaft. Crankshaft position sensors, which ensure that the vehicle starts and remains running, are one of the most important components of an engine.

Crankshaft sensors are used in most modern fuel-injected automobile engines and monitor the revolution, speed and position of the crankshaft. The vehicle’s onboard engine management computer uses that information to help the ignition system produce a spark and manage valve and cylinder position as gasoline is injected into the cylinders. When operating properly, the crankshaft, valves and cylinders are synchronized to provide optimal timing and engine performance.
