Crank Shaft Position Sensor

A crankshaft position sensor failure will usually trigger the check engine light.

Crank shaft position sensor.

The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. A crank sensor is an electronic device used in an internal combustion engine both petrol and diesel to monitor the position or rotational speed of the crankshaft this information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. The crankshaft position sensor relays this information to the vehicle s onboard computer the engine control unit ecu. 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.

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. Before electronic crank sensors were available the distributor would have to be manually. A faulty crank position sensor can prevent your vehicle from starting so when it s time to replace or upgrade this device autozone has everything you need. The check engine light illuminates for many reasons one of which is.

Replacing the crankshaft position sensor is fairly easy on most vehicles. Without a crankshaft position sensor the engine wouldn t start. The crankshaft position sensor measures the rotation speed rpms and the precise position of the engine crankshaft. The ecu uses that info along with inputs from other sensors to control systems like ignition timing and fuel injection.

All the modern vehicles have the crankshaft position sensor it is a component for monitoring the crankshaft s rotational speed and position. In some cars the sensor is installed close to the main pulley harmonic balancer like in this ford in the photo. This keeps all the parts of the engine well timed and working in concert. It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning.

Here are some of the common symptoms to help you determine whether or not your car s crankshaft position sensor is damaged. If you think your sensor has failed here are some common symptoms of a bad crankshaft sensor that can help you in determining whether or not it has failed.
