China Crankshaft Sensor Hyundai 39180-26900 Crankshaft Position Sensor The crankshaft position sensor measures the rotation speed (RPMs) and the precise position of the engine crankshaft. Without a crankshaft position sensor the engine wouldn't start. he crankshaft position sensor is abbreviated to CKP. Cuando selecciona OEM genuino, puede confiar en la alta calidad y eficacia del producto sin tener que adivinar si funcionar谩 con su Hyundai.

The reluctor ring has one or more teeth missing to provide the engine computer (PCM) with the reference point to the crankshaft position. As the crankshaft rotates, the sensor produces a pulsed voltage signal, where each pulse corresponds to the tooth on the reluctor ring. The photo below shows the actual signal from the crankshaft position sensor with the engine idling. In this vehicle, the reluctor ring is made with two missing teeth, as you can notice on the graph. The PCM uses the signal from the crankshaft position sensor to determine at what time to produce the spark and in which cylinder. The signal from the crankshaft position is also used to monitor if any of the cylinders misfires. .If the signal from the sensor is missing, there will be no spark and fuel injectors won't operate. The two most common types are the magnetic sensors with a pick-up coil that produce A/C voltage and the Hall-effect sensors that produce a digital square wave signal as in the photo above. Modern cars use the Hall-effect sensors. A pick-up coil type sensor has a two-pin connector. The Hall-effect sensor has a three-pin connector (reference voltage, ground and signal).
