ABS Light on

[whitelightning99]

It's been on ever since i bought the Expo in September last month, i have not got it on the road yet still needs a little tlc and i need funding to get tags and all that so i can do so.also it sat for 3 years too,but anyway i crawled under it on the top of the rear end i took the speed sensor out cleaned what i could while it was unplugged i noticed that when i turn key to on the light come on then went out ???? not sure why that happen i would think it being unplugged that it stay on regardless.so that happening makes me think that it is the speed sensor is bad an reason for the light on. I check the plug with test light with key on i didnt get it to light up might have just been i couldn't get a good ground connection with the test light

I always ground my test light straight to negative on battery. Then I run a long extension to where I'm working. That way you never have to keep searching for ground. I think I bought my long extension from a matco tool truck. If your handy make your own. As to your abs light, you might want to pull up any codes. Brakes are something you want to get a handle on right away. A lot of shops and parts stores should be able to scan for you. Whether it's free like engine codes, couldn't tell you. Guys are their places that pull up brake codes for free?

Possibly could be the abs relay was removed from under the hood, due to the abs pump being stuck on. I would check that first
