1997 Pontiac Grand Prix Automatic 142XXX miles

Could someone please tell me why when I'm driving now all of a sudden the ABS, Check tire pressure, Trac off lights come on? I just started happening yesterday and the only way to get them off is to turn the car off and then back on and even then they will still come back within 5 minutes later.

Whenever a dash light comes on, the first thing you need to do is have the computer scanned for codes. This will point you in the right direction.

AutoZone and any major parts store will do this for free.

Typically, when there's a problem with the ABS/Trac system, it's usually a wheel sensor that has failed. However, if your tire pressure becomes low, that makes that particular tire spin at a different speed than the other three wheels. So the computer can't operated the
ABS/TRAC systems properly. So that will also set a code.

But there's a few other possible causes. If you have the computer scanned, we can narrow it down.
