Crankshaft Position Sensor A

The crankshaft position sensor is sometimes used to provide data for an instrument panel tachometer as well.

Crankshaft position sensor a. Because the sensor ckp is used to determine which cylinder is firing to synchronise the fuel injector and coil firing sequence. In other cars the sensor could be installed at the transmission bell housing or in the engine cylinder block as in the photo below. The crankshaft is connected to the bottom of the pistons and rotates as they move downward after combustion. One of the important components of your vehicle s engine management system is the crankshaft sensor or crankshaft position sensor.

Whether you re backing out of your driveway or coming to a stop at the end of the road your ride depends on many intricate components such as the crankshaft position sensor to function well. 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 sensor voids the need for manual distributor timing. There are two primary shafts inside the engine the crankshaft and camshaft.

This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. The data provided by the crankshaft position sensor is used to determine when the engine s ignition coils will provide a spark and when the fuel injectors will deliver fuel. It sends this power to the transmission allowing your car to move. 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.

The crankshaft position sensor plays a big role in making sure your engine runs smoothly. In some cars the sensor is installed close to the main pulley harmonic balancer like in this ford in the photo. The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. A properly working crankshaft position sensor is critical in monitoring the phase of your engine which gets communicated to your vehicle s computerized engine management system ensuring a smoother and safer ride.

So the crankshaft position sensor ckp monitors as a multi functional sensor used to set ignition timing detect engine rpm and relative engine speed. Automotive crankshaft position sensors provide engine rpm and crankshaft position data to the engine computer. Without a crankshaft position sensor the engine wouldn t start.
