Tire pressure light won't turn off after changing tires

dead sensor battery?

 

Did you reprogram the car to the new TPMS sensor codes?

Does the '06 wheel set even have TPMS sensors at all? I'm not sure they did, the feds didn't require it in 2006.

 

yes, if you know they were working on the '06.

 

That's your answer. Reprogramming the computer to know the specific sensor IDs is essential to getting a proper reading. Without that, you get the observed symptoms.

Any Toyota shop or tire shop can do this, though for a price since you didn't pay them to install the tires. There are tools to do this yourself, but they are not cheap. Check around with your car enthusiast friends.

But to do this, you/they must first find the sensor ID codes (also readable with special tools). And ...

This is the $300-$400 question. I don't think the 2006 Prius had them, so you'll need to buy and get them installed.

Or, you can simply cover the light with dark tape, then maintain your tire air pressure the same way that 2006 Prius owner, and virtually all drivers of that era, did. Check periodically with a gauge.

 

The TPS are a POS cover them with a piece of tape


iPhone ?

 

Did the wheels off of the 2006 Prius have wheel sensors in them or no?

 

If those wheel have sensors at all, it should be $20-75 to have a shop read the sensor IDs (using a special RFID reader through the tire sidewalls) and program them into the car.

But beware that if they have original sensors, the batteries should be at or near end of life, requiring full sensor replacement. The coin cell batteries are generally sealed in, not separately replaceable, so new sensors are needed.

If those wheels lack sensors -- which is what I suspect from the model year -- expect roughly $300-400 to buy and have them installed. With such purchase and installation, programming the car will be included at no extra cost.

Numerous drivers of my generation don't feel TPMS is worth this cost. If you are good with old fashioned tire management, i.e. periodically do manual pressures checks like drivers were supposed to do before TPMS was rolled out about a decade ago, then you may choose to skip the sensors. If so, just cover the annoying warning light with tape. Just remember to peel it off before selling the car.

If you choose to skip the sensors, then you are committed to bolting and unbolting the wheels to the car yourself. The tire and car shops are not supposed to do this, defeating the overall TPMS system, but car owners may do so.

 

Even if the 06 wheels had TPMS w/ working batteries, the OPs 2008 is looking for the TPMS from his 2008 wheels. The 2008 vehicle would have to be reprogramed w/ the unique ID each sensor has, assuming the 2006 wheels even has TPMS.

OP has five options:
1) Ignore the dash warning light of low tire
2) Put electrical tape over the dash warning light.
3) Reprogram the 2008 w/ the IDs of each sensor from the 2006 wheels (assuming these wheels even have TPMS w/ a functioning battery).
4) Get a set of new TPMS for the 2006 wheels.
5) Mount the 2006 tires onto the 2008 wheels.
