Disabling TPMS
 

Is it possible to disable the TPMS. IThis is a feature that I would just assume do with out. I keep up with my maintenance, checking tire pressure regularly. With the fluxuation is temperatures, my TPMS light is always going off, and my tire pressure are just were I want them. I would just assume shut that alarm and light off permanently. How can I make this happen?

no its not possible man this suck i know

You have three options:

- Ignore the light (i don't even notice it anymore)
- Cover the light with electrical tape
- Study the FSM, i'm no engineer but it looks like there is a way to disable it. There are notes about the system being off so i guess it's possible. Also, the BCM diagrams show you where the TPMS receiver resides.

Interestingly, there's also a note about a DVD player. I guess that was designed as an option.

This is what I did for my car when I upgraded to new wheels and tires. They were already mounted and balanced when they were shipped to me so was unable to transfer the sensors over. So of course they light was always on. Total cost of this fix was about $14 from local hardware store and takes about 15 minutes. Here is the shopping list:
3" PVC Pipe Schedule 40 About 4" long
2 3" end caps for each end
PVC cement
Heres what you do:
Glue one cap on the end of the 4 inch pipe. insert 3 of the 4 sensors into the tube. I wrapped in bubble wrap to keep from vibrating. In the other cap drill a 3/8" hole in the center and insert the last remaining sensor with valve stem up through the hole and retighten down with the existing retainer from valve stem. Glue this cap onto the other end of tube. Let glue dry for a few minutes and then simply air up the tube to 35 psi. I placed the tube in with my spare tire so its out of the way. Your computer now thinks all tires are aired to 35. You can now have what ever rims and tires you want and have them at what ever psi you want with no light in the car!
Hope this helps.:biggthumpup:

Man, now that's thinking outside the box!

I've heard of this fix before but never got around to experimenting with it.
Glad to hear it worked for you.

Sorry .. no way this will work on the 2nd gen (at least not mine?). I had 2 fully inflated stock rear wheels and tires (with TPMS) inside my car while I was experimenting with new rear wheel and tire sizes. The light will still come on.

your wheel has to be spinning for the sensor to send a signal how else do you think the sensor gets power.

^ It has to spin for power????

(they're battery powered)

I wonder if the car was shielding the sensors from the receiver?
Maybe mounting underneath on the chassis would work.

It would not make a difference. According to FSM section WT, page 7 - the tire pressure reciever picks up the pressure signal from each tire and sends the data to the BCM. The tire pressure receiver is located inside the car near the upper left of the glove box.

TPMS light came on my car, checked pressure, everything is good, dead battery?

I'm having the same issue. TPMS stays illuminated but pressures are good. It does not go away.

on the V36 sedans/coupes you need to get the sensors reset if your tpms lights are on

you can either pay 120 at the dealership or free at discount tire

Thanks for the info. Is there a DIY to resetting the sensor? Or do you know of any other places that would reset the sensor for free or cheaper than dealer? Unfortunately there are no discount tire's near me.
