I figured out last year that the LOW tire pressure yellow dash light can be for the spare tire as well. On an 08 it is not easy to get to the spare tire without raising the vehicle on a jack.

Well it got cold again and on came the light again.

I have maintained my own vehicles for 20 years and periodically check the spare tire air pressure which is probably more than most do. I do not need this pain in the butt monitor coming on every winter for the spare tire. I have never had a spare tire be anywhere near flat when I needed it.

Can I disable just the spare tire sending unit or whatever it is called only ?
Thanks................

 

Spare Tire doesn't have a TPMS on Caravan. Just check the rest of ur tires, make sure they are over 38 PSI. Placard recommendation is 36psi, you need to fill it up to 38+ PSI to get rid of the light.

 

Spare tire DOES HAVE A SENSOR as this was the only tire I added air to because I had just checked the others when I changed the oil.

So yes the spare tire has a sensor as well.

 

Most of the space saver tires don't have a sensor. Did you add a full size tire?

 

Really? the Caravan has a Donut as a spare, and not a full size like Jeeps. From what I've remembered, I've never seen TPMS on Donuts.

 

Sorry to dredge up an old thread but I just wanted to confirm what everyone (except the OP) has said concerning the compact spare and TPMS sensor.
