Hey Scotty! I’ve got a 2005 highlander with 227,000 miles on it, the tire pressure light keeps coming on even though all 4 are inflated properly, including the spare. Do you know what else can be causing the light to come on? Thanks
Just a wild guess here, but maybe the 20-year-old batteries in the tire pressure sensors have gone dead?
Also, for future reference please use the title line of your post for a short description of your car issue, not the full details which belong in the body of your post. Thank you. (Title edited.)
All my older cars I just replace the tpms with one that screws on the valve stem. They cost about $25 and read each tire pressure so you can see what they are, and it will alert you if they go too low.
Electrical tape over the light will fix that issue as well.
