The crankshaft position sensor relays this information to the vehicle s onboard computer the engine control unit ecu.

Crank shaft position sensor.

It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning. The ecu uses that info along with inputs from other sensors to control systems like ignition timing and fuel injection. It monitors the position and rotational speed of the crankshaft and sends the information to the engine control unit so it can make appropriate adjustments based on operating conditions. Monitor your engine s overall function as well as the speed of crankshaft rotation by investing in a high quality ultra durable crankshaft position sensor.
