TPMS issue?
I got in the car today, and said left front tire pressure was low. I checked it with a regular gauge and it was good. I just added chrome wheels that I got from a local seller off his 2006. I still have my old TPMS on my other front wheels and hope to swap them out, but do these go bad after a while? Thanks.

I'm not clear on the situation, but maybe the car is still picking up the pressure in the old wheel...in the same garage??
Unless the car was re-programmed to the new TPMSs, it would do this. The battery in the TPMS sensors is thought to be good for 10 years.

Do your new wheels have TPS's? Assuming they do, did you use a TPMS tool to register the new sensors with the car? If the TPS's need to be 'reset' I'd look for a Discount Tire store near you. I know my local DT will reset your sensors this free of charge (I suggest you call first to be sure).
You might want to search for the TPMS instructional videos by BEZ06 (the forum's resident expert on the subject). It's good to have a basic understanding of how they work and what's involved to reset the sensors. If you go to DT to have them set the sensors it only takes a couple minutes.

I agree with cclive something isn't clear. If I read correctly, you installed new wheels, tires and sensors on the car. Also, If I read correctly you still have your old wheels, tires and sensors (likely in the garage with the car).
Did your tire shop register the new sensors to the car?
If they did not perform the activation procedure to have the can learn the new sensors you are likely picking up a low pressure condition from the old wheels near the car.
The car can only store four sensors and they are stored by location (left front, right front, left rear and right rear). If any changes are made to the wheel location, the sensor location or new sensors added they will need to put the car in learn mode and teach it about the new sensors or new location. If this isn't done, it will simply continue to look for the old sensors.
Tire pressure sensors can be damaged. They also have a battery in them (not serviceable) and it can go dead or get weak over time.

Do your new wheels have tire pressure sensors in them?
If so, then they need to be programmed into the TPMS computer in the car. The TPMS can only store 4 sensor IDs in its memory, so your old sensors may still be programmed in there. And, like cclive says, if your old wheels/tires/sensors are stored in your garage within 30 or 40 feet, the car will pick up transmissions from them and display their pressures in the DIC.
If your new wheels have sensors in them, you don't need to swap your old sensors into them - just program the new sensors' ID#s into the TPMS.
The sensors have an internal battery inside and they will go bad eventually, although the design life of our sensors is 10 years.
So....if your new wheels came with sensors in them, just program them into the TPMS so the car recognizes them.
