What‘s the crankshaft position sensor?

The crankshaft is a rotating assembly inside the engine that connects to the pistons and connecting rods.
When the engine is running, the linear motion of the pistons causes the crankshaft to turn, thereby creating the rotational force needed to move the vehicle.

The CKP sensor measures the position and speed of the engine’s crankshaft.
The sensor creates a signal by reading a toothed or notched wheel that is usually located on the crankshaft or harmonic balancer.
For this reason, the crankshaft position sensor’s location is often at the front bottom side of the engine, though, its location can vary from vehicle to vehicle.
