Last week I was working under my car to try and remedy an annoying clunking noise, which involved removing all four aftermarket wheels.
After everything was remoiunted and I drove around a little I notice that the low pressure sensor light next to the speedo and the PSI light in the gauge pods are always on.
Since I 've had the aftermarket wheels (6 months) this has never happened.
I think I may have accidentally knocked the sensor out of place in the wheel- well and it's sending a false signal.
Trouble is, I can't find the sensor to put it back in place. Any ideas where it's located? Thanks,

 

Well, I assume you transferred your TPS sensors into your aftermarket wheels so they are either attached to the valve stems like stock, or banded to the rim on the inside.
Did you dismount the tires or just take the wheel off the car and put back on?
You can try taking that wheel off the car that's complaining and see if you hear anything inside when rolling it around. Maybe it came loose depending on what you did.

 

This may be a silly question but you realize they are mounted to your wheels inside the tires? They are not in the wheel well as you described. If you strapped them to the aftermarket wheels and they came loose, I would dismount the tires as soon as possible because you could shred a tire.
