1999 Elantra 2.0 Camshaft Position Sensor

May 06, 2007 2 Replies

I was wondering if anyone would know what the signal waveform should look like, coming off pin 2 of the CMPS, on a standard oscilloscope?



Will it be a clearly identifiable square wave / pulse train of some sort or will it consist of ultra thin "spikes"?



Thanks!



The cam sensor puts out a 12V square wave. Of course, if you use a large enough time scale on the scope, it'll look like thin spikes.

On this site is the complete shop manual, including wave forms. It helped me a lot with maintaining my 1996 Lantra wagon and with troubleshooting in one case.
