Your car’s crankshaft position sensor (CPS) is a critical component that helps your engine run smoothly. If the CPS fails, it can cause a variety of problems, including stalling, rough idling, and poor fuel economy. In this blog post, we’ll discuss the symptoms of a bad CPS and how to fix it.
The CPS is a small, round sensor that is typically located on the side of the engine block. It uses a magnetic field to detect the position of the crankshaft, which is the main shaft that connects the pistons to the transmission. This information is then sent to the engine’s computer, which uses it to control the timing of the fuel injection and ignition systems.
