If your camshaft position sensor is sending inaccurate or inconsistent data to the ECU, or if it stops sending data altogether, you're very likely to notice a drop in your car's fuel economy.

The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The 2026 Subaru Impreza gets minor updates and a ...

This paper describes a dual-track magnetic crankshaft and camshaft position sensor configuration. It uses semiconductor sensors such as magnetoresistors to pick up the magnetic flux modulation created ...
