Default Tpms?

Hello everyone. 2012 wrx here, stock tires and wheels. This morning it was in the low 20's and the tpms light came on. I checked the air pressure in all my tires but none are low. Has anyone else had this issue?

Those sensors tend to be very sensitive. When the weather changes dramatically they will get set off. It should go away after a bit of driving if the pressure is correct.

Find a station that will fill nitrogen. Also, takes 5 miles of driving iirc for them to get a new reading if they change.

was just a thought about the spare. if not, 1 sensor might be faulty. take it to the dealer for warranty.

There is no sensor in the spare. If the pressure is correct a short drive should fix the issue. If it persists one of the sensors may have a bad battery or may just need to be manually reset. If you live near a Costco with a tire center they should be able to do this for free.

The TPMS flips out every winter on my parents' 2009 Legacy. I tell them to not worry about it because well, all the tire pressures are within spec. I actually run winter tires without the TPMS linked up with the computer. Just make sure your tire pressures are good and keep driving

tpms sensors always go nuttly when cold. In the manual it states this and tells you that its normal. Check your tires weekly. I use a bike pump to pump em up and have my tire gauge to set the exact psi that I like.

To my knowledge there is indeed a TPMS sensor in the spare. This happened to me this year. All four of my tires were at spec'd psi but my TPMS light was still on. Checked spare and it was low (although it looked fine). I pumped it up and TPMS light went away.

Just had one of mine replaced a few weeks ago on my 08. The tpms light would flash a few times at start, and then stay on for good. Replaced under warranty, otherwise, $150. Ridiculous.
