Be very clear that there may be differences in wiring between your Ion camshaft sensor and a Hyundai camshaft sensor. I do not have wiring info for Ions so I will use my L300 for reference purposes Use your judgement when info is given.

My L300 uses a crankshaft and camshaft sensor. The crank sensor is a two wire device that generates its own signal (no 12v or 5v input). L300 camshaft sensors are supplied 5v on the gray wire. A purple/white wire is the output signal. Black is ground.
