Tire sensors - '05 Grand Cherokee Laredo

I have a 2005 Jeep Grand Cherokee Laredo. Had a new tire put on a week ago because of a flat and they used the rim from the spare to put the new tire on, instead of the regular rim. No big deal because they look the same, but now my tire pressure indicator light keeps coming on. Checked the tire pressure and all are good. My question is - where is the sensor located? If it's on the rim, then maybe there is no sensor on the rim from the spare? Or the sensor is bad? If it needs to be replaced, how difficult is it? Do you need a dealership to reset it so the indicator light goes out?

The tire pressure sensor is built into the valve stem on my 2006. Pretty sure yours is the same. It could be that your spare doesn't have the sensor built into it, but more likely the battery is dead. The batteries can't be replaced. You have to periodically replace the sensors. They run around $65 each, but if you look around, you can get them for about $25 each online. I bought one this past summer and have another one that needs replaced right now.

Check Partsgeek.com. I found mine for $24.60 there.

I'm pretty sure that the spare tire doesn't have the tpms in it. I would take it back to te shop that did the work and have them switch the tire back to the old rim. Should be free since they did something weird.. I've never heard of putting a new tire on the spare wheel. What did they do with the wheel that had the bad tire on it? Sounds like a big switcharoo lol

Some years have a sensor in the spare and some don't. If it is there, and functioning, the system would auto detect it. I'd also recommend taking it back to the tire shop and tell them to make it right. Also ask why they used your spare maybe they damaged your other wheel and didn't want you to see it
