is there a way to add the TPMS system to the 04/05 model? What would this type of mod involve?

 

anyone?

 

don't bother. just check you tire pressures manually once in a while. it really isn't hard.......

 

Sure you can, there's an aftermarket TPMS system you can add to any car, it comes with a basic display unit (looks like a radar detector) and an advanced display you can mount anywhere you like.

Here's the link:

You can't add the factory one though.

 

Why not if you order all the appropriate parts?

 

would be silly to try. you would have to build or modify wiring harnesses and buy many updated parts and hope they are compatible with other systems on the car. example.... instument cluster will probably not have the software in it to display any tire pressure warnings. I would immagine that would be expensive if even possible to change to a later cluster due to software version changes within other control units that it must communicate with on the car. not to mention most cars have a tire pressure monitoring control unit. how are you going to wire that into a car that it wasn't made for???

 

Do a search here in the forum. I got a list of all the parts needed, somewhere around $500-$600. I think communication from the wheels is wireless. The only unanswered question is the software. Still, I doubt I'd try to do it myself.

 

I honestly don't know exactly how the acura system works. german cars anyways, the tire pressure sensors are wireless with a standard radio requency sent to one or more antennas in the car, then the antennas are hard wired to a control unit. acura did this very differently? $500 or $600 at least on an audi will get you the pressure sensors that go into the wheels, but that's about it. we've had customers buy them to put in a second set of wheels for winter, which is why I know that ballpark number.. I know we aren't talking about an audi, but.......

 

I think there is a wireless receiver near each tire. There is no programing involved, so that is the only way it would be possible. If there was just one receiver, how would it know which tire is F/R or F/L.

Personally I think you're better off just buying a new car if you want TPMS that bad.

 

some cars have a reviever at each tire like BMW. others use one central antenna. it knows the difference in wheels because each transmitter broadcasts a different serial number type code. and yeah, in those systems, rotating the tires requires modifying an electronic setting so it knows where you put each wheel.

 

There's 2 components at each wheel. The valve stem and a separate sending unit mounted behind the wheel that's location specific so rotating the tires wouldn't mean having to change anything. The only other thing different not mentioned in this thread is that the '06 wheels have a concaved area immediately around the valve stem. Not sure what purpose that serves though.

 

At a minimum you'll need 4 sensors at $44.58 each, 4 initiator units at $31.70 each and 1 receiver at $181.75 for a total of $486.87 and that doesn't include any wiring or other unknown items.
