97 Grand Prix GT "check tire pressure" light on

[fju2]

Where is the sensor that measures tire pressure? I've searched and it almost seems as if the tire pressure indicator is built into the hub? This just sounds strange, as my simple mind doesn't understand how the hub sensor can detect low tire pressure.

For the record, the "Parking Brake" and "Trac Off" lights are also on. I'm thinking they all have to do with faulty hubs, or sensors built into the hubs. Plausible? Thanks, all.

It is based off wheel speed. When one is reading faster than the rest it thinks its low. Sounds like you have a bad hub get the codes scanned.

Thanks for the quick reply. Would those type of codes be scanned through the OBD port?

yeah you need a scanner that will do abs tho.
