TPMS BAD

[rlc3854]

I have a bad TPMS on the left rear wheel, tried resetting and moved to another location and no effect. Never had this happen before on any vehicle. This is a 4 1/2-year-old vehicle with only 40K miles. Should I have all 4 replaced instead of just the bad one?

I have yet to have a TPMS sensor go bad.
You may want to have it checked first by an independent tire shop. To keep the shop honest. I would not tell them which TPMS you suspect as being bad. They should not even have to start the truck to determine which one is bad.
My 23 drops random TPMS quite frequently. On our fourth of July trip last year. It became a guessing game, which one it was going to be.

Here is a good example. 35 miles later

Like magic. They're both working again.
The sensors are perfectly fine. They always comeback with 20 miles.
I attributed to the cheap computers or terrible software.

Good Luck

If you have a Discount Tire nearby, they will check your sensors for free.
Usually better replacement cost than a dealership as well.

Probably just manufacturing defect on the 1.

Not going to sleep on non-movement like it's supposed to, or way too long before it does - wore the battery out.

Happened to me. I have a second one that is bad, but haven’t fixed it yet.

I figure it's like these valve cap lights I'll get for the bike for a night ride event.
They are cheap - not spending much money on a once a year event.
The are supposed to light up when they detect movement.
One is supposed to flash lights according to RPM even.
Had a bad one - couldn't detect it was spinning so never turned on.

Yet a simple old one I had was a little wimpy spring inside - when spinning the spring collapsed and battery made contact and it lit up.
That works no problem.

The newer ones using I'm sure a cheap accelerometer chip.

Of course the TPMS is also tracking temp besides pressure. I think I saw a scanner PID on that.
