Crank Shaft Position Sensor

The ecu uses that info along with inputs from other sensors to control systems like ignition timing and fuel injection.

Crank shaft 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. The crankshaft position sensor is usually mounted on the front of the engine near the front crankshaft hub. All the modern vehicles have the crankshaft position sensor it is a component for monitoring the crankshaft s rotational speed and position.

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. 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. It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning. A crankshaft position sensor failure will usually trigger the check engine light.

This keeps all the parts of the engine well timed and working in concert. Before electronic crank sensors were available the distributor would have to be manually. The check engine light illuminates for many reasons one of which is. The crankshaft position sensor relays this information to the vehicle s onboard computer the engine control unit ecu.

The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. 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 crankshaft position sensor can fail for various reasons and its failure leads to a number of engine related problems. Replacing the crankshaft position sensor is fairly easy on most vehicles.

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. There are a number of reasons why a crankshaft position sensor can fail and a number of symptoms associated with that failure problems with the crankshaft position sensor will often present as problems with engine timing.
