Crank Sensor Voltage and EDIS

Post by capri_turbo »

I'm looking to make myself a benchtop simulator using an Arduino to simulate the crank sensor. The code to get a 36-1 tooth pattern is really easy and it basically gives a 5V square wave output.

My question is, what is the maximum Voltage that the EDIS can handle from the VR sensor?

I was thinking of using a simple Voltage divider to drop the square wave to around 1Volt, but if the EDIS will hapily tolerate 5V, I'll just leave it as it is.

All sorted. It seems that the old EDIS isn't too fussy about the signal and as long as it goes negative, it'll trigger just fine off a 5V square wave... I just simply added a voltage divider to put the vrs -ve line at 2.5V and all works just fine off the little arduino... much safer than mounting my spare trigger wheel on the desk in a drill chuck...

aha ! square wave gets a mention.
I am new to all this stuff and learning square waves are from Hall Effect sensors and for MJ/E plus EDIS is supposed to not be square , but whatever Variable Reluctor sensor produces.
No wonder I am getting confused :)

It will definitely not work with a square wave hall effect style sensor! :)
