Camshaft Vs Crankshaft Position Sensor

The speed and position of the crankshaft are two key parameters that the car s computer uses for engine management calculations.

Camshaft vs crankshaft position sensor.

A crankshaft position sensor gives the engine computer an accurate reading of what angle the crankshaft is at in the 720 degree 4 stroke process. The camshaft position sensor tells the computer which 360 degree portion of that 720 degree process is currently happening. They tend to be located in the valve cover since most engines these days are overhead cam design. If any symptoms are.

The camshaft is a rod with specifically placed protuberances that stick out from the rod. Instead use these methods and test crankshaft and camshaft position sensors once you know the type of the sensors. The camshaft position sensor gathers information about the vehicle s camshaft speed and sends it to the vehicle s engine control module ecm 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. 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.

So you may understand how important it is for the sensor to work without any glitch. The camshaft position sensor gathers information about the vehicle s camshaft speed and sends it to the vehicle s engine control module ecm. Do not drive with a malfunctioning crankshaft and camshaft position sensors. Crankshaft sensors can be a pain since the crankshaft is located on the bottom of the block.

The ecm uses this data to determine the timing of the. The camshaft position sensor is typically located in the cylinder head of the engine and has a cylindrical portion that inserts into the head. The position sensor on your car s camshaft continually assesses the frequency at which the camshaft is turning. These are called cams.

Without this information the engine would not be able to function properly. Testing a 3 wire sensor requires many steps we have used japanese cars whose sensors work perfectly. Camshaft sensors tend to be easy. The camshaft sensor monitors the frequency at which the camshaft is turning.

When the camshaft turns the individual cams push against specific valves and cause them to open. When the cam rotates away from the valve the valve closes.
