im haveing problems with my ask i guess, i went and had my tires changed and the ***'s put one 225 and one 235 tires on front. so i noticed my slip,abs,and novdc lights are now on , is this cause of the tires? or think it could be my abs sensor? i just put on new rotors and pads and its still on so i dont know.... where is the abs sensor located?

 

you have mismatched sized tires on the from and you are wondering if that is causing a problem with a sensor that bases its input from wheel speed?

 

the exact thing happened to me and my car. the only difference is that i have the right size tires on the car. the same lights turn on as welll. i have no idea what it is. i took it back to the place where i got my tires changed and they arugued with me and told me that there was no way they could have done any thing to make those lights come on.
