Guys i can't figure out how to connect 0261210104 crank sensor from fiat punto gt. The issue is that i can't find any proper manual and get sensor working. I don't know if my jumpers are set correctly. On megasquirt forum i found that guy only wired signal and ground wire to connector.

How should i wire that connector, i tried many ways but nothing is not working. What i do wrong!?

Don't know does this matter for crank but this look a bit burnt to me?

Is it VR or Hall?

How do you know it's not working?

Have you read the wiki?

Should be hall sensor, i know that it's not working because i can't get rpm signal on ecu while cranking

[jonbill]

have you shared your tune?
you'd get no RPM if the board and sensor are fine but you've selected wrong board or wrong trigger pattern (or other...)

Should be hall sensor

With Bosch ID number you gave documents say it´s VR-sensor and you don´t have VR-conditioner.

Pinout is: 1=Vr+ 2=Vr- 3=shield ground

If this is a VR sensor and you have connected it without a conditioner you may have damaged your Arduino.

Hope you have a spare.

There are ways to figure out if you have either sensor but you generally check this first before connecting it so you don't cause damage.

And that part number is 100% a VR sensor not a Hall sensor.

How should i set my pull up jumpers then if it's VR sensor?
Here is my base tune if somebody can check it please?

Do i need to set 5v or 12v then with jumpers

So if i get right i need to connect
1 pin on VR1+
2 pin on VR1 -
3 pin on GND

Read. The. Wiki.

It's covered in the jumper configuration in the wiki
