abs light

Hey Guys Ok Heres Is My Problem. Sometimes When Coming To A Stop My Brake Petal Will Raise Up Like The Abs Is Engaging. Then The Abs Light Comes On The Dash. I Think Its A Sensor. But I Dont Know Which One It Is. Because I Believe There Are Two Sensors That May Cause This Problem. There Is A Wheel Speeb Sensor And An Abs Sensor. Now When The Light Comes On I Have No Abs. So I Guess My Brakes Will Lock Up. Does Anyone Know Which Sensor I Will Need.

You need to have the codes read to see which sensor it is. You have 4 wheel speed sensors. More than likely it is a sensor that is not reading properly. The only problem is you need a scanner that is capable of reading the ABS system. I think the chain stores only read the PCM codes.

Not to step on way2old's toes, just an idea-pull the front & rear rotors off the car & check the abs sensors & rings out visually. You probably have one that's really dirty. Brake cleaner & regular old red shop rags work great to clean them up. Compressed air helps. We clean them in our fleet at every brake pad & rotor swap. If that doesn't do it for you, you'll have to get an ABS capable scanner on it like way2old says.

No problem on the toes. :biggrin: That is good advice to give. If you have a feeler gauge, you can measure the air gap on all of them also. Should be around .040 inch. Thanks BMFer1 for pointing him in the easy direction. :smokin:

thanks guys!!
