Wave form

01Z06.....Could someone show me what a cmp sensor wave form looks like on a Tech 2? Mine looks like stair steps instead of a square wave.

A Tech 2 does NOT show a CMP waveform...you need a DSO (digital storage oscilloscope)...is this what you’re using ???....this is a cam-crank correlation waveform on my scope on my ‘01...bottom blue waveform is crank and top red is CMP.

You will only see a true CMP waveform
using a DSO...you want to be looking at a voltage over time waveform...this is not the true waveform one would use to diagnose a faulty sensor.
