What’s the tire pressure on a Cadillac DTS?

2009 DTS, 110,000 miles. This morning the dash said “check right front tire pressure”. I scrolled to tire pressure and it said it was 65 PSI. I knew that can’t be right, so I checked it with a manual gauge and it was 32 PSI.

Is the tire pressure sensor on my Cadillac going bad?

I drove it around and it was moving up and down from 79 PSI to 55. When I got home, I bled the air down to 20 PSI and put new air in to 32 PSI. Now it is reading 35-45 PSI. Is the sensor going bad? I read you can change the battery.

How can I tell if my tire pressure sensor is bad?

If they don’t have the tool to relearn the new sensors you can do it yourself. Scroll through the menu on the info screen in the instrument cluster and follow the instructions. The marker light or tail light for each wheel will light up, let some air out until the horn beeps.

How old is the tire pressure sensor on a Cadillac?

I do work on cars quite a bit, but never the tires. The TPMS sensors inside the wheels are now over 11 years old – probably time for new sensors. I don’t believe the lithium battery is renewable. The relearn tells the system which sensor is in which wheel – done with a decent magnet and horn honk procedure.
