The service manager at our local Chevrolet dealership told me over the phone that it is possible for the customer to program an aftermarket tire pressure monitor sensor themselves and that the instructions for doing this are in the owners manual. I have a 2010 Aveo. I have searched through my owners manual and cant find anything about programming the TPM. Can someone shed any light on this?

According to the owner's manual a TPMS (Tire Pressure Monitor System) diagnostic tool is needed. The sensor identification codes need to be matched to the tire/wheel position.

Was their any documentation included with the aftermarket sensor?

I encourage you to take the vehicle in for service.

I knew that it sounded to good to be true. I'll probably put the light out with black electrical tape and use the same tire pressure monitoring system that my 98 Ford Ranger has, my eyes and a pressure gauge.

 

since this is the title i would have used if i made my own thread i figure i will just use this one.
what is the deal with the tire pressures going up and down. is that normal? one day i will check the display and they will all be 35, then the next day they will all be 32 then the next day they might all be 37. is this normal? i got the onstar diagnostic report back and they said i had low tire pressure but the next day the display might say its normal. should i do anything?
im driving a 12 cruze ltz

Tires need the correct amount of air pressure to operate effectively.

Notice: Neither tire under inflation nor over inflation is good.

Underinflated tires, or tires that do not have enough air, can result in:
- Tire overloading and overheating which could lead to a blowout.
- Premature or irregular wear.
- Poor handling.
- Reduced fuel economy.

Overinflated tires, or tires that have too much air, can result in:
- Unusual wear.
- Poor handling.
- Rough ride.
- Needless damage from road hazards.

The Tire and Loading Information label on the vehicle indicates the original equipment tires and the correct cold tire inflation pressures. The recommended pressure is the minimum air pressure needed to support the vehicle's maximum load carrying capacity.

Pressure fluctuation is due to temperature and is considered normal to a degree. This is precisely the reason the tire manufacturers specify inflation pressure for a "cold" tire, or not been run yet. Normal operation of the tire causes a slight temperature increase, which causes the tire to expand, thus giving a higher psi reading. Environmental temperature should also be taken into consideration.

If you are concerned, consider consulting with a technician for a tire inspection.
