Is there a way to verify a hall sensor type?
I needed a hall sensor for my driveshaft speedo pickup for my Racepak. I went to my local auto parts store and bought a BWD "cam position sensor" off some buick that will fit size wise. It is a 3 wire sensor, and it is likely a hall sensor which is what I need. Is there any test I can do to verify it's type without a scope? Also, it does not have a pigtail only imbedded pins. So I need to figure out which wire is the 5vRef, which is the output and which is the ground.
Any help? |
Have you tried searching the part number on the internet to find out if it's a hall effect? I know the sensors on my buddy's northstar are coil style. They are more like an abs sensor that reads cut out notches in a wheel.
Here is what you need with a simple bracker I guess. http://www.diyautotune.com/catalog/h...sor-p-489.html |
Yeah I have. It just says cam sensor. I think my neighbor may have a scope. I'll check.

Yeah I'm aware of DIY's sensor, thing is I need it now not in a few days. I have to do emissions and if my speedo does not work I will fail. And I need to get my car on the road by wed.

If it is three wires then it probably is a hall effect, only problem is if it switches with a flying magnet or ferrous material and the pinout... post a picture.
Oh I just saw no pigtail... well a commonly used convention is ground on the left, then signal, then power... but it really could be anything. Also, youll need a 1k ohm pull up between power and signal if the racepak does not have it. Just swap the pins around and look for a signal on your multimeter, if connected right the signal output will show 5v normally and pull to ground when a tooth is in front of it. The sensors can usually survive being connected wrong while you experiment. |
Yeah I just played around with it on a spare battery and my multimeter. A few times I got the full 12V without even putting a magnet to it, but I couldn't get it to jump when it was reading like 0.05v without a magnet there.

You positive it is triggered by a magnet? You gotta make sure your using the south pole too.
I just edited my last post too. |
I belive so.
