What Does A Camshaft Crankshaft Position Sensor Do

The camshaft position sensor gathers information about the vehicle s camshaft speed and sends it to the vehicle s engine control module ecm.

What does a camshaft crankshaft position sensor do.

It is a component for monitoring the crankshaft s rotational speed and position. All the modern vehicles have the crankshaft position sensor. It uses this information to adjust the spark timing and the operation of the fuel injectors. This data is then sent to the powertrain control module pcm for use with fuel injector and or ignition system control.

The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. The ecm uses this data to determine the timing of the ignition as well as the timing of the fuel injection that the engine requires. Common symptoms of a faulty camshaft position sensor 1 check engine light illuminates. It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning.

To determine which cylinder is in its power stroke your car s computer monitors the rotating position of the camshaft relative to the crankshaft position using a camshaft position cmp sensor. The ecm uses this data to determine the timing of the. The purpose of a camshaft position sensor is to determine the position of the camshaft as it relates to the crankshaft. The crankshaft position sensor ckp sensor or cps is one of several sensors that keep your engine running smoothly.

Alongside the crankshaft sensor the position sensor on the camshaft is an essential for the modern car and is used in all sequentially fuel injected engines to ensure optimum performance. The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine which is particularly important in engines with variable valve timing. Most camshaft sensors are mounted just above a notched ring on the camshaft. The position sensor on your car s camshaft continually assesses the frequency at which the camshaft is turning.
