Camshaft Position Sensor (CMPS): Notes
WARNING: This page is about a different car, the 2005 Hyundai Accent and 2004 Hyundai Accent. However, it is still accessible from the selected car via links, so may be relevant.
The camshaft position sensor (CMP Sensor) senses the TDC point of No.1 cylinder on its compression stroke. Its signal is fed to the ECM to be used to determine the sequence of fuel injection.
