So about a week ago my abs and rear antilock lights started coming on when I would accelerate, they would shut off as soon as I got up to speed but now they are on permanently. What sensor is causing this and where is it located any comments are helpful.

 

Check your brake fluid level

 

It is half full I'll fill it and see if the lights turn off. If they don't, any other recommendations?

 

Filled it and the lights haven't come back on. Thanks.

 

I would check the brakes pads. If the reserve was half filled that means your pads are worn down..

 

Yeah I know my rear brakes aren't working too well. But I'll have to check the front as well. Thanks
