ABS light on

[Panco469]

I got the ABS light on. How can I now which sensor is bad?

Are you certain you have a bad sensor? If the light is on constantly it could be...

If it comes and goes it might just be a dirty sensor. Sand, gunk, grime... anything in there can mess it up. Especially if you have blown struts and that stuff starts leaking out all over, happened to me.

Other than that, I'm not sure how to tell which is bad, if that's the case.

You need the dealer DRB3 tool to read out which sensor is bad. Hopefully you can talk them into the 5 minutes of reading it and telling you which is bad, then you can "decide what you want to do". If they don't charge you for the read, then order the sensor from them and install it yourself. If they do charge you then order the sensor from S&P and install it. Dealers almost always charge for doing a computer scan (way too much for 5 minutes of work) and if they are being kind to you then return the favor and stay on their good side and order the part from them. You may need their help later.

So you guys are telling me to clean them and if the light still on, go to the dealer.
Ok

I had/have this same problem. I took it to a dealer and they were going to charge 96 dollars for the scan. Then they saw my warranty had expired in Feb. but I was still 9K short of 36,000 miles, so they pulled some strings and did everything for free. The had two codes, one for a bad wheel speed sensor and one for a bad ABS module. They replaced the wheel speed sensor and ordered a new ABS module.
