where are the tachometer sensors??
Can someone please tell me where I can find the tach sensor(s) ? My tach has been bouncing around lately, and I'm hoping its the sensor,s and not the gauge itself. If anyone has any info they can share , that wouyld be great.

I have the Mazda workshop manual, and could not find anything on the tachometer. I'll look at the tarnny section. Thanks.

Duboisr is right and it is not responsible for your tach bouncing. It is the fact that the tach itself is bad and need to be replaced. It is a common problem that is cured by replacing the gauge.

My own reasoning for it not being the gauge is this. If the guage was in fact bad I would expect the needle to suddenly fall towards zero then jump back up to the previous revolution. But the particular problem I have with mine is that it occasionally zooms up, which varies from 200 k to 4000k. I have not been able to recreate the problem at will and it seems to do this randomly. Does my reasoning seem logical, or am I missing the obvious?
BTW, I read and reread Diboisr's post, and still do not understand his point.

Yes it may very well be the gauge itself. But a mechanic at Mostly Mazda ( m2 performance ) did mention it could be the sensor(s).

read the wiring diagrams and see where the signal comes from.
