Vehicle speed sensor

6speedsd · Jan 17, 2013

Is there a way to test if one is working as it should? The one in the rear end. Not ABS. Wondering if it is acting up and causing my trans issues. Don't want to just replace it if there is a way to test first.

Input anyone?

With an oscilloscope you can look at the output of the sensor. It is a square wave with 8000 pulses per mile. Or you can use a scan tool and read the sensor output from the PCM.

The ones I found around here were listed for like $75. Wasn't at the dealer though. Advanced Auto I think. The ABS sensors were that cheap though.

Mark,

I have AE, but I think you've told me once before that you weren't familiar with it. There is a way to read vehicle speed, but I think it only reads in mph. Ill have to double check that to verify though. Is there something in particular, I should look for to read? Mainly what would that parameter be called. I'm still learning what all those parameters mean!

I'm using tapatalk so I can't see sigs but I literally bought one a few months ago from autozone for 15 for my 2000 f350
