Located in the timing cover, or on side of the block with a cylindrical portion inserted in the block, crank sensors (a.k.a. crankshaft position sensors or crankshaft sensors) set ignition timing, supply the RPM signal, and determine engine speed. Crank sensors can fail due to excessive heat, faulty wiring harnesses, and sensor movement.
To ensure durability under extreme conditions, we subject each of our crank sensors to extensive end-of-line testing, including a 48- to 64-hour-long vibration test across three different planes. For a closer look at our crank sensors, including their premium components, watch the video above.
