The crankshaft sensor is an essential component of your engine management system, without which your vehicle will not function properly. Based on this information, it sends a signal to the DME that allows it to determine the correct timing for the ignition. Crankshaft position sensors can be located on the crankshaft pulley (aka harmonic balancer), the flywheel/flex plate, or on the fuel pump on some diesel applications. Along with this information is the exact rotational speed and position of the crankshaft.Depending on the make of the vehicle, the CKP information is used by the ECM to properly time the spark, and deliver the fuel, while on some relays it is only for misfire detection and doesn’t really control the timing of the spark. The crankshaft position sensor is nestled under the engine block just above the starter. Typically, the sensor is only held in place by one or two fasteners and is relatively easy to swap out.
