This is probobly a stupid questions, but when I went to order a 12 bolt the other day, they asked me where my abs sensors were? 1 on each side of, or 1 on top of the pumpkin? i didn't know, and im not sure id' know what i was looking for if i looked under the car. Can someone tell me for a 2001 car?

 

Cars with traction control have the 4-channel ABS; cars without have the 3-channel setup.

 

That is not always necessarily true. According some some manufacturers and other techs, there are a few out there that do have TC and aren't 4 channel.

To properly determine if you have 3 or 4 channel abs get under the car and look and see if you can tell if there is a wire going into the pumpkin or if you see 2 wires going to each axel (aside from the brake lines). The 2 wires going to each axel would indicate you having 4 channel abs. Hope this helps.
