When you buy a new car, there are a few things you need to do before driving it off the lot. One of those things is to check the engine’s ” camshaft position sensors “. This article will explain what these sensors are, and what they do.
What are Camshaft Position Sensors?
Camshaft Position Sensors (CPS) are sensors that are installed on the camshafts of a car to help determine the angle of the camshaft. This information is then used to control the engine’s valves. There are typically four CPS in a car, but some models have as many as eight.
What Do Camshaft Position Sensors Do?
When you start your car, the engine’s camshafts engage the valves and start moving them up and down. The position sensors help the computer know where each cam is at all times, so it can adjust fuel and air mixture and spark timing as needed. When the cams are in their “sweet spot”, the engine runs most efficiently.
How Many Camshaft Position Sensors Are In A Car?
A car’s camshaft position sensor (CPMS) is an electronic device that helps the engine control the timing of camshafts during combustion in order to optimize fuel economy and performance. The CPMS sends signals to the engine control unit (ECU) to adjust the timing of the camshafts.
There are typically two CPMSs installed in a car: one on each side of the engine. Each CPMS monitors a different bank of camshafts. If there is a problem with one of the camshafts, the CPMS will send a signal to the ECU telling it to skip that camshaft’s firing sequence. This can help improve engine performance and fuel economy.
