TPMS Light blinks, then remains ON .Air pressure about 38 psi on all 4 corners.The spare tire had only 26 psi, now 38. Any thoughts? Thank you.
TPMS sensors sometimes go bad. You might need to replace one of the sensors. A tire shop may be less costly than a dealership. Go to one you trust or try to find one using the Yelp app on your smartphone or tablet.
TPMS sensors have batteries that are designed to last 7 to 10 years. You may need to replace the sensors.
