What Is A Cam Sensor

May 20, 2019

A camshaft sensor is an integral part of the modern automobile. All modern cars feature a sensor on their camshaft.

7 Symptoms Of A Bad Camshaft Position Sensor And Replacement Cost In 2021

The CAM tells the computer the position of the camshaft and works in sync with the crankshaft sensor so the computer knows when to fire an injector depending on model and to fire spark.

What is a cam sensor. This information is relayed to the cars ECU and used to help fine tune spark timing as well as injector pulse. If a camshaft controls those valves what is a camshaft position sensor and why is it necessary. For safety purposes disconnect your cars positive and negative battery terminals by unscrewing the nuts near them with the 12 inch wrench.

The Camshaft Position Sensors communicates with the vehicle as to where in the rotation the camshafts are. Camshaft position sensors monitor the camshafts position and send information to the ECU about when each valve is open on a particular cylinder. Here is how you can easily test both your crankshaft position sensor and camshaft position sensor.

Turn it off and wait several hours for the engine to cool off. They work closely with crankshaft position sensors to paint a more complete picture for the ECU. With data from the camshaft position sensor CPS the fuel injectors know when to fire.

You may have trouble spotting the sensor when you look under the hood of your car. As the shaft rotates the egg-shaped cams or lobes push the valves open in sync with the crankshaft gear. The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive.

The example here is my 2006 Nissan Murano but these types of sensors work the same wa. The camshaft sensor is located under the hood beside the engine however it isnt always easy to find it. The position sensor on your cars camshaft continually assesses the frequency at which the camshaft is turning.

So what does a camshaft sensor do. This is because the exact position. This sensor is a very important part of any vehicle because it helps ensure that the engine is running properly.

Cam sensor resistances and the location of the sensor vary with your vehicles make and model. The camshaft position sensor monitors the position of the camshaft and reports that data to the cars onboard computer system. Every modern-day vehicle has a camshaft position sensor.

It is one of the devices that helps the engine run smoothly. Move your vehicle to a well-lit area. 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.

What does a camshaft sensor do. The white smoke is more related to coolant or oil leaks bluish smoke into the combustion chamber. Its function is to monitor the rotation of the shaft and notes when the valves are open and closed.

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. This computer system works with sensors and other devices to keep the engine running. This information is required to calculate the ignition point and injection point among other things.

On this page you can find out how a fault on the camshaft sensor can manifest itself and which steps should be taken during troubleshooting. Comprised of two distinct parts the cams and the shaft the camshaft is the element that enables valves to open. Please note that sometime Cam faults may be a res.

Heres a brief look at exactly how a camshaft position sensor operates. The camshaft position sensor gathers information about the vehicles camshaft speed and sends it to the vehicles engine control module ECM. Its very important to be able to test these sensor since.
