Got a tire pressure warning, spare in door jamb .isted at 60 psi, even stamped on the full size spare 60 PSI. New to me, I wonder why. It is not monitored for pressure.
Curiously 3 tires were at 30, and one was 33, recommended pressure. I don’t get that!! Filled em up light still on, off to the dealer I guess.
If you have a full size tire as a spare then 60psi is wrong . That should be the Maximum pressure not the operating pressure . Some vehicles monitor all four and spare but that usually does not apply to the temporary donut spares.
I expect the 60 psi for the spare is correct. Does your tpms warning system tell you which tire is the problem? Or just that one or more of them has an incorrect pressure? My guess, one of the sensors or its battery has failed. Sensors fail from time to time, ask Boeing’s ex-CEO Dennis Muilenburg.
No reset I saw in the manual or info screens. I’ll check the pressure before we hit the interstate on our return. It is supposed to correct after driving.
Could be the pressure sensor’s that have failed, Mom was given a $800 estimate to replace all 4 by the dealer compared to around $400 for the independent on her 2010 Prius. 60psi sounds right for the spare, It’s the same on my Forester.
If a sensor fails the warning light will flash for one minute after start up.
A common problem is for the low pressure thresholds to be set too high by someone fooling around with the initialization button. For now set the tire pressure at 36 PSI to see if the warning light goes out.
