ok so i've searched and from what ive read and heard, the '07 tc does not have something welded to the rim? im not totally sure because alot of the posts ive read where different from one another. so can somone clear this up b4 i get myself into a lot of stress if i were to end up having to get the sensor taken off the stock wheel and welded on to my new set of wheels im hopefully going to get soon

 

I didnt think it was welded... But yes, there is a sensor in the wheel on the 07's. It has to be removed and placed in the new tire unless you want your tire pressure light to always stay on.

 

not welded but needs to be swapped and reset or else you get a TPS light!

 

It's the "lump" on the inside of your valve stem. The valve stem is held in to the wheel with a nut on the outside.

Remove the tire, remove the nut, remove the sensor from the inside of the wheel, replace the seals, put in new wheel, tighten nut down, put tire on, etc.

The sensor/transmitter will fit on many aftermarket wheels, but not all.

oh sweet! thanks "tomas"

 

This kinda sucks for ordering wheels/tires since the tires have to removed from both sets of wheels...is there anyway to just disable the sensor in the car?

 

Just break the bead on the stock 17's and pull them out, then break the bead on the new wheel / tire if already mounted, and insert them and reseal your tire. Sucks cause you will have the opposite problem on your stock wheels, if you winterize like me, and use them. TPS sensors are dough! 600 I'm hearing, that's 150 a piece :-o

 

...plus reprogramming the car-mounted receiver to accept the new transmitters if you use two full sets - they are serial numbered, and the receiver will only pay attention to the four it has been trained to accept.

Changing back and forth twice a year would get to be a PITA. (Also remember the lithium batteries in the transmitters only last about 5 years, and are supposedly non-replacable - new sensor time...)

So I guess the important question is here: "Which method is best?"

- A - Ride with sensor light on
- B - Swap your stock sensors between stock and aftermarket rims, causing you to have to break the bead everytime you do so, not to mention reprogram. PITA.
- C - Buy new set for your aftermarket wheels, so you can just swap your wheels each season w/o having a bish of a time doing so! I might opt for this route, but 600.00 seems a little steep, it is however the do it right or dont approach.

 

- D - get a wheelbarrow wheel and put all four sensors on it. then inflate the wheelbarrow tire to the correct pressure and ride with it in your trunk, or back seat.

 

Excellent!

 

LMFAO

 

Couldn't resist. :D

Oh that's hot! Where can I score one of those?!

 

dont go breakin any bead with them in, they break easy..take the valve core out so the air comes out, with a 12mm sockent loosen the nut on the outside (its not really a nut but its the best way to discribe it) and push it into the wheel so you see the opening in the tire. then u break the bead and take the sensor out...especially on a lower pro tire your askin to break a 300$ sensor

 

I take it the 07 sensor is a different set up than that of the previous generations?? If I am correct the 06 and prior tC only measured the rotational speed of the wheels?

 

Well from looking at my sensor guide here in the office, and researching, the older tC's have them in the axles, these new sensors are in the wheels, sort of like a satellite, which sends a signal to the ECU every some odd rotations. Take them away and you break the signal, actually, the light has been off for the past week now since my first post lol, the car must have said f*** it this nucka aint got no sensor, so Im gonna ignore em' now lmfao.
