I'm hoping a mechanic can help me with this.

I need to get my car through inspection..

The ABS light on my dash will be on for a few days then if I hit a bump just right it goes off. Then another day I hit a bump and it comes back on.
The brakes were done last year, so they are fine. Is this just in the wiring, or are there sensors.

When my check engine light was staying on it ended up being a 500 dollar job to fix the sensors..

usually the abs sensor is under the car- exposed to the element- when it lit up in my truck- it also took out the speedometer and odometer- be careful when you are driving-

its probably your sensor - just my experience but im not a mechanic

so if it goes off and on when I hit bumps it's because the actual sensor is being hit by the bump ....? Like when I pull in the driveway to fast it happens

This happened to me a few years ago and I thought it was the sensor as well. I left it go for a long time and then eventually had to have the entire ABS system replaced, cost me over $1500 to repair.

So my advice is go have the car checked out and make sure it is nothing major

quite possible- you also might have a short - go get it checked- cuz you only have one kind of braking system when the ABS system goes out- it shouldn't cost too much- do you know any guys that like to play with cars? they love to do that stuff- any auto parts store has it

Sounds like a wheels sensor. Depending on the car, pulling the fuse for the A.B.S. will reset the light. Autozone will rent you a Automotive code scanner for a small fee. With that scanner you would be able to clear any indicator lights before a inspection. I had the same problem with my 99 grand am. I just pulled the fuse on the A.B.S. computer and didn't have a issue or any warning lights. But now most car manfactures are smarter than that and will light the brake malfuction light. As long as there is no pulling, grinding or squeeling, your ok.

No, I don't know anyone here..let alone one who plays with cars..
Thats why I posted, thought a mechanic could tell me more.

I'm thinking just a short because it only changes from on to off when I hit a bump...I don't want to get ripped off by a shop..

I appreciate you ladies responding Thank you flowerforyou

Great..thank you very much..so I need to pull the ABS fuse and if that doesn't work get the scanner from autozone...

Thanks drinker

I just looked, none of the fuses are marked ABS, or brakes..

You may have more than one place where there are fuses.

It could be a lot of things. Not a short but an open. That is when a wire is broken. A short is when a hot lead is connected to ground. As the Englishman said a bad "earth" or ground wire that is loose is also possible.

There are speed sensors on each wheel. One of their wires may be loose or frayed. You need to go under the car and look around the wheels for anything that looks out of place.

Best to get to an auto store or library and look up the manual for your car and then check out the brakes section. Also getting a code reader is a good idea. You will need a list of the codes also. Rent one or get a cheap one anywhere from fifty to well over a hundred dollars.

If it is an intermittent problem and the light doesn't stay on yes it could be wiring. It could also be a very big PITA to find.

Where is the front abs sensor located on a 1997 Chevy Cavalier?
it should be located right on the back of the wheel assembly

:thumbsup:

You are very welcome. I have worked on antique and sports cars and motorcycles for years. Nobody is going to be able to fix your car over the internet
But if you have any technical sense and are good with tools, with the right manual and maybe a few broken fingernails, you should be able to do it yourself. Or at least gain some knowledge to where a shop isn't going to rip you off too easily.

1997 Cavity.laugh There are two fuse boxes. One inside the car for the radio, windows, heater, and things like that. Then there is also one under the hood. In the one under the hood there should be one marked A.b.S., check the owners manual for its location. These won't be your average fuses, there much bigger. They control just about every thing that makes the car run. Just find the proper on and pop it out then start the car To make to shure all your vitals are working. You should not see any warning lights. Diffrent cars vary, but did this same fix to my grand am and worked very well. No A.B.S. means your breaks will lock in a panic stop. Keep the fuse you pop out, Every three thousand miles the light will come back on. just pop it back in, start the car to clear it, then pop it out. Easy easy fix.
