2019 4Runner, about 37k miles.

My tire pressure indicator is on all the time. I drive for a couple of miles (light off), then it blinks for maybe a minute, then it's on for the rest of the drive.

I've checked the pressure with two gauges. Running about 33-34, with recommended pressure at 32.

I've got stock wheels with snow tires mounted, which I put on in November and take off in April. I've got another set of stock wheels (purchased used), with regular tires, that I run the rest of the year.

Both sets have OEM tire pressure sensors. And the spare is the original, with the original OEM dohickey.

When I switch sets do I have to have some kind of adjustment done to the car to have the tire pressure indicator work?

What tire pressure should I be running? I've been told to run about 2lbs high to get the indicator light to go away.

If I can't get this fixed simply then I'll remove the indicator bulb I guess.

Suggestions?

Thank you.
