ABS sensor test with meter?

[drjkel]

"What AC range is it set to?" Actually I went to an oscilloscope at 10millivolts/div and saw nothing. I later verified that I have hall-effect sensors.

A measurement of the current through a hall-effect sensor is required to verify functionality.

The meter was set to auto range and it saw nothing. I tried to check the amps, but nothing there either. I have a two standard Fluke Meters (model 77 and 87).

I think I have resolved my original problem though, I forgot to swap over the rear ABS rings when I installed the new hubs. I thought they came with them.

Still, it would be nice to figure out how to test individual wheel sensors with a simple meter if possible. I have access to a scope and I may give it a try as well.

thanks,

Send me your email address, I will send you a copy of the Pinpoint test.

Hey Guys, adding to my rep points will not hurt my feelings. LOL I sent you guys that requested the pinpoint test an email copy. I did find out that the pictures will not show up BUT if you have a fax machine, I will be happy to print it out and fax it to you. Thanks guys, I hope this helps.

a meter will not work to test a sensor, it can tell you if the coil is bad with ohms, but to test the sensor and tone wheel you need to have an osciliscope. it will show you the wave patern and any hickup in that will be shown on the screen. it switches back and fourth too fast for a meter to pick up.

You can use a meter for the active sensor, an AMMETER. It is acurite enough to test the sensor and the tone ring, you just have to go very slow. HOWEVER, an osciliscope would but the best and most perfered method. But not everyone has one they can use and it is for more likely that you can get a meter. Besides, at the dealer and here in the classroom, we use the multimeter.

Thanks for the info and help. I need to get an o-scope and check it out when I get the car back together. I ordered the tone ring today ($30).

Also, I added to your rep, but it hasn't shown up. Won't let me add to it again.

Thanks,
Vincent

Don't sweat it. Those of us who have been on here long enough don't pay attention to rep points. Some of the most knowledgeable people on FF have low point values. I won't get in to the reverse situation.
