TPMS Wackiness: Had A Flat, Didn't Indicate it; Tire Is At Shop, Still Shows Pressure. What Gives?

Scrappycrow · Wednesday at 12:37 PM

So, this morning I came out to a flat on my '13 LTZ. I must have picked up the screw within 1/4 mile of home, as it had little wear on it.

I jacked that corner up so there was no weight on the tire, then started the truck to see what the TPMS said, but it read that tire only 1 psi lower than the others.

Even after I left the wheel & tire at the shop and drove well out of range, it still showed pressure in the tire (albeit now 4 psi lower than the others).

What's going on here?

Thanks,
Scrappy

Sounds like a dead or faulty sensor?

If you have one of those handheld sensor reprogrammer tools, you can go around each tire and check the status of each sensor.

Good idea, thanks! Just a few days ago, I picked up one recommended by folks here (OEC-T5 EL-50448 from Amazon).
