I was zooming along the interstate. At the speed limit, of course.
And a dashboard light came on with a loud Ding. The light told me there was a problem with Tire Pressure.
I pulled over at the next safe opportunity, got the tire pressure guage out and checked for which one was low.
All four tires had 26 pounds. None looked flat.
Back in the car, started the engine thinking the light would go off.
Nope. Same light, same loud Ding.
Time went by as it always does and the light stayed on for several days and the Ding donged every time I started the car.
I diagnosed the problem as being in the warning system itself, or in the valve stem of one of the tires. Both of these were problems far beyond my ability to fix.
Took it to the people who know way more about this stuff than I ever will.
You’ve probably already figured this out, but the problem wasn’t the warning system. The problem wasn’t a valve stem, either.
The person who explained the problem to me has a great ability to keep a straight face.
Turns out all four tires were just low on air. “No charge, Joe. Thanks for coming by.”
Let’s get back to this tomorrow. Right now, I gotta get my tire gauge out and be sure the air pressure’s okay today.
