Standard Motor Crankshaft Position Sensors
These Standard Motor Products replacement crankshaft position sensors are designed to send a signal to the ECM to determine engine rpm, crankshaft position, and engine misfire. They consist of a permanent magnet, yoke, and coil. The Standard Motor Products replacement crankshaft position sensors are mounted close to a tooth gear. As each tooth moves by the sensor, AC voltage pulses are inducted into the coil. Each tooth produces a pulse; as the gear rotates faster, there are more pulses produced. The ECM then determines the speed at which the component is revolving, based on the number of pulses. Therefore, the number of pulses in one second is the signal frequency. If you're experiencing crankshaft position sensor failure, try one of these Standard Motor Products replacement crankshaft position sensors.
