Swaped rims to black steelies & blizzaks for the winter 2 days ago. I have yet to have the TPMS light some on. When i got the wheel/tire pkg from tirerack.com they said it did NOT support the TPMS,. So now my question is do i have a late 06 badged as an 07? maybe the system is not working correctly/?

i have not check the new rims to double check that there are no sensors in there, but for the cost i got them for.. i highly doubt it..

Is it normal for the light NOT to come on? 150miles or so later?

Not normal. They should have been on the stock rims. They won't call an 06 an 07, check your registration. It should have been inside the tire where the valve stem was.

it is an 07.
Might stop at the dealer tomorow to check the system. Not that i really mind NOT seeing the light come on , during the winter tire change.

car makers actually start calling their cars 2007 as early as May or June . example, if you look at the door sticker and see "8/06" it could be called an 07 model. so come june/july/aug of 07, it might be labeled as an 2008....

check your door sticker and check your underhood label for verification

I think the point was that they wouldn't call an 06 model and 07. not that one would be an 07 in 2006. The fact of relabeling an 06 as an 07 would be misleading.

It is very possible that the dealership did not properly activate your TPMS during pre-delivery service. To see what I mean, see http://tijil.org/Scion_TSBs/pd03806.pdf

not true. if anything is left over from the 06 model year at the manufacturing plant when they start turning out 07 vehicles, then it is very likely for an 06 to be badged as an 07. its usually not likely, but it has happened on many occasions with many different manufacturers. take for example when the new OBD II system first started appearing in vehicles, there were quite a few GM vehicles that ended up with OBD I systems matched with OBD II system connectors. you should see the confused looks on people's faces when they try to connect OBD II scan tools to that system. thats just one example, ive seen many others from working in the automotive industry.

thanks thomas, i might bring it in and make them do that.. but i really enjoy NOT seeing that light with these tires, so i may wait till the 1st oil change

Look in the glove box, is there a reset button for the tire pressure sensors?

(Both old and new systems have the reset button...)

being in the automotive field....i stand by what i said

OK, guys, the absolute simplest way to determine the model year of ANY vehicle is to look at it's VIN.

On all newer vehicles sold in the US, the tenth digit of the VIN indicates the model year. (Required by federal law.)

If your VIN says "6" in the tenth position it is a 2006, if it says "7" it is a 2007.

May I go to bed now? :yawn:

480 miles later with the steelies.. the friggin light came on.. weird. i was just sitting at the drive through at DD, and it started blinking.. so i guess it works.. took damn long enough.
USELESS system IMO

well.. that settles it..

Uh, settles what? Either system could have done that. :D

Tomas

Just check your valve stems. If they're rubber, you do not have the sensors at all. If they're metal, you have the sensors but they may or may not have been activated. If they are metal but you don't believe they have been activated, just take it to the dealership. Tire shops use a type of scan tool that activates the sensors.

well.... each sensor has a specific serial number that has already been pre-programmed into the ecu to match for that certain car.

there is no way to know what that serial number is unless you take the sensor out and actually look at it.

during the PDI process, you're supposed to reset the pressure sensor system... not much really an "activation".. moreso... hmm.. "wake up"? if that makes any sense...

I have an 07 and i was wondering if it would hurt my car to ride around with new wheels on it without the sensors? Also if there was anything i could do to make the light go away other than black tape over it lol

it would be bad... but not life-threatening..

why don't you just put the sensors in the new wheels??

how would it be bad? Cause i don't want to take them out of the stock wheels cause i wanna use the stock wheels during winter and new wheels during summer and i don't even know if the sensors will fit the wheels that i want.

dunno. but if it was me.. i wouldn't do it.

yes.. i know the hassle of swapping them out... i've had to do it for someone.

If you plan on switching wheels back and forth each summer and winter, you clearly have the money for two sets of wheels and two sets of tires. If you have the money for two sets of wheels and tires, you have the money for two sets of sensors. Problem solved.

You shouldn't have an issue with the sensors fitting inside the rim. The sensors are flat on one side, and that side goes against the rim. The sensors are sealed onto the hole in the rim where the valve stem comes out. The sensor and valve stem are all one piece, therefore the entire unit is sealed onto the rim.

The alternative to that is going to be extremely time consuming and not too easy without the proper equipment.

you do understand that when you switch sensors like that... you need to reprogram the ecu to accept the other sensors each time...

you can't avoid the fact you're going to have to remove them from the wheel... (even if you have two sets... you need to know the serial numbers for all 8 sensors... only way to find them? on the sensor itself, inside the tire)

bad? to run without sensors? WTF would it casue to be bad... Screw the sensors, just check your damn tire pressure occasionally. what did people do before cars told them thier pessure was low, or to frickin paralle park themselves... Sissified drivers now-a-days.. jesus..

yeah i never even knew cars had tire pressure warning crap until i got a new tc. all it does is make it more of a pain in the ___ to put aftermarket wheels on. i would just say fck the sensor when i get the new wheels but then the tire pressure warning light will probably be on 24/7 on the dash for the rest of the time i have the car. i don't know who i want to punch.

i don't know who i want to punch.

Maybe the feds? It's federal law that is requiring the new tire pressure monitoring system. Scion was perfectly happy with the earlier system on the tC that didn't require expensive sensor/transmitter units inside each tire with only a five year battery life.

Tomas

All I want to know is if it is gonna hurt anything on my car if i ride without them? And if once i put my stock wheels back on can i just press that tire pressure reset in my glovebox to make the light go away?

yeah...sounds like the best thing is to:

A) forget about having the sensors in your new wheels
B) press the TPS reset button in the glove box to turn off the light
C) hope that the tire pressure system doesn't NEED sensors to be present to keep the light off
D) and when you put the stock tires back on, hope that the TPS picks up the wireless signal from the sensors

All very optomistic, I know.... :wink:

ehh. that light's gonna come back on no matter how many times you reset it

im totally lost here.

why do you guys think we have in-tire pressure sensors?

that low pressure light comes on when the wheels spin at different speeds, according to the ABS system, as I understand it.

I'm thinking if you knowingly omit the tire sensors, you're going to have some sort of warranty issues.

Granted, I don't know what would be affected by the tires not be properly filled, or what circumstance this would come up. Though, soon as it starts becoming a standard practice, I have no doubt in my mind someone will get into a situation where not having the sensors in the wheels will send them up a creek w/o a paddle ...

they changed that in 07, as tomas said before ...
the 07 tire pressure sensors actually sit in the valve stem, also as stated before, and measure the actual tire pressure, not just the estiamted pressure like prior systems.

interesting... thanks!

Too many lazy people that refuse to do anything for themselves. All it takes is a drive to work to find some dumb ___ driving around on a mostly flat tire. Gotta love the govt for helping these people with stuff like that instead of solving real problems.

just for the record, the light will NOT go out, even if you press the button, it will come back on soon enough.

I have put 800 miles on the car with NO issues, with the steel wheels, and NO monitors.

The question i have though,,, when i pull the gauge cluster to swap the leds, if i just remove that light bulb, i wonder if i will have issues getting a sticker at the dealer, i know ways around a dealer sticker, but i just wonder, being a new law and all, how close they are going to look for these lights, as i am NOT willing to pay the extra cake to install monitors in the new wheels, and i refuse to mount/dismount my winter wheels just to install the stock monitors, that is the reason i got a seperate set of rims/tires in the first place, to remove the hassle of it all.

How 'bout putting black electrical tape over that LED when you have things apart, so that it will not show through? That way if it needs to still work later, you just have to open things up again and peel the tape off...
