Does the RL have one? 05 of course.

 

Of course... Tire Pressure Monitoring System (TPMS)...

 

Yes. Not only does it tell you if a tire is low in air pressure, you can actually read the pressure of each tire via the digital display.

 

I am amazed that the 04-05 TL does not have one.

 

Expect it to be there for 06. I believe post 05 the govt has mandated TPMS on all vehicles.

 

NHTSA's Final Rule on TPMS:

Good post, thanks. Points for you

 

Lots of interesting info in there.

 

The caddy deville had that for years.

 

350z, too.

 

Thanks for this link!!! Very useful info.

 

For those of us who run a seperate set of wheels for winter, and don't want to buy another lot of monitors, there is an outfit that produces valve caps with LED's which flash if pressure drops by 4 PSI. They self set after you install them and are good for a couple of years. At $25 including shipping for four, I think this is a good compromise to the expense involved with buying exra monitors/fitting/and balancing wheels. They are called "Air Alert" at web site www.aviationupgrade.com

 

Why not just buy 4 transmitters from acura and have them mounted on the rim?
the system will read them with out an issue.

 

As I said, if you are already running on your snows, this is a quick and easy way to keep an eye on the pressure without the trouble of having to have the sensors installed and the wheels rebalanced.
