Is tpms supposed to beep when tire full?

Or a change in the weather. As a rough rule of thumb, tire pressure will change by 1 PSI for every 10 degrees F change in temperature. Drive from Las Vegas to Mammoth Lakes this time of year and you could lose 5 psi in a few hours.

Yup. My TPMS went off after driving from Santa Barbara to Palm Springs. About a 20 degree temperature change.

The main limitation is that if all tires lose air pressure equally, there is no low indication. Honda's indirect TPMS is a cheap out.

Honda's indirect TPMS uses two detection methods:

1. Wheel speed differential (diagonal, front/rear, and left/right comparisons). During calibration, the TPMS measures and learns the rotational speeds of the wheels. As a tire loses air, its diameter decreases which causes the wheel speed to increase. If the difference in wheel speeds exceeds the threshold, the low tire pressure indicator turns on. This method is effective if one, two, or three tires become low.

2. Peak tire resonance. During calibration, the TPMS learns the peak resonance frequency of the front tires (about 42 Hz). The peak resonance frequency drops as the tire pressure drops. The resonance frequency also changes with temperature, so it is corrected using the outside air temperature sensor. If the peak resonance frequency of the front tires drops below the learned value, the low tire pressure indicator turns on. This method is effective if all four tires become equally low.

Both detection methods utilize the four, individual wheel speed sensors to measure rotational speed and peak resonance frequency.

That's cool. And if the resonance of the tires deviates from 42 Hz by changing to another brand or model (if that's possible?), running the calibration after changing tires & wheels will teach the computer the new resonance value -- right?

My TPMS has gone off 2x in the last 2 weeks. Normally I have a 25 mile commute each way...and temps have been in the 93-96F range.
Took a trip and drove 195 miles each way...about 125 miles in...each way, the TPMS went off. when got to destination, hit the recalibrate. No other light for the week I was at my location. On way back home...about 125 miles in...went off again. Temps both days were running about 98F. Here 10 days later back to my day to day driving 25 miles each way...have had no issue.
That is annoying as hell. Will get to test it again in September on a 850 mile round trip....

In theory, yes.

It may be of further interest that when you change the wheel size (i.e., upgrading to the 19" HFP wheels), you're supposed to have a dealer use their HDS to reprogram the TPMS threshold so that it can operate properly (i.e., reduce false alerts while still alerting before the tire becomes dangerously low). The available selections are for tires and wheel combinations provided by Honda. The installation of aftermarket or invalid tire and wheel combinations can result in incorrect operation of the TPMS (and affect the handling, safety, and crash performance of the vehicle).

Hopefully the tires were at the correct cold inflation pressure before and after your adventures. Did you check pressure/variation between all tires when the issue occurred?
Very few posters are reporting issues for short/long trips and large temperature variations when all tires are at the same/correct pressure cold.

I didn't just because I was short on time when I arrived at each destination...but will check that on next long trip. They are all at correct pressures right now however (I did check them about 4 days after I got back) and I haven't put air in any of them since before that trip.....so they theoretically are fine. They don't need air at all right now.

thats good to know its 4 speed sensors and a learned method, so tire changes are possable.

I've kept mine at the 32.5psi on the door jam of my `17 Touring Sedan. Tires ware evenly, good gas mileage, no squealing around corners. Also probably good because of the upgraded tires - Michelin Premier A/S.

Yeah, this definitely sounds like a heat issue then.

i got a set of aftermarket wheels with mazda 3 tpms sensors in them, i dont think theres a problem keeping them in the tires for my winter studds, do you guys think that would be a issue?

Nah, they won't make any difference because the system only reads off the hub. I had an issue though with my new wheels and I thought it was a nail or something in the tire. The tire place checked it over and said it was probably it didn't seal properly when they swapped the tires the first time so they reseated the tire and no problems so far.

They'll be fine (as long as the lug holes and centerbore fit, of course). The Civic shouldn't even have a receiver to acknowledge the sensors in the wheels; it won't know they're there.

i got the adapters for hub bore to make them fit.
