I have tried everything to reset the constant tire pressure warnings on my new 2019 passport. Yes I did add air to the tires. I even added extra air to 38 psi to make sure the pressures were not too low.
I cant find any where where I can calibrate the sensors. I tried the internet. No Joy It does not appear to reset itself even after several drives.
Help.

also I searched every menu under settings. Duh.... nothing

There is nothing to do to calibrate, if they are at the recommended pressure all you have to do is drive and the light goes off. If it’s not going off then the TPMS DTCs are not clearing for some reason, sounds like a trip to the dealer is in order.

The first warning was with the arrival of COLD weather in the chicago area. First I brought the tires up to 36 psi, and waited. warning kept coming up
Then I tried 38 psi warning continues after several hours of driving. all 4 TPMS DTC are affected at various times. I would have preferred a clearing/calibration setting or no devices at all in the good old days. It alarmed my wife today when there was no concern at all. The end result is that we will ignore all such warnings in the future, which is probably not good either

There has to be an issue then because when we got our first cold spell all 4 tires dropped, I inflated them all to 37 and literally drove less than 1/4 of a mile around my work compound and the light went off in less than a minute.

I believe you have to be above a certain speed for several miles for it to recalibrate. If you haven’t already, take a 5 min drive somewhere that you can maintain at least 40 mph for a bit. If still no go, I’d take it in.

 

[Jermboy777]

40 seconds of 15mph+ is Honda’s procedure. It doesn’t even take that..

That appears to be the relearning of the sensors and their location, not pressure. The manual seems to convey it will reset itself just by the pressure being where it needs to be without any driving at all. It’s really pretty vague about it imo. My Honda’s of the past always had to be driven a ways to reset or recalibrate (my ‘18 Si had a recal function). I suppose if the system is showing the pressure is at or above on the instrument cluster and you’re still getting the warning, dealer will have to fix.

We keep almost all our 18 inch and larger tires at 38 psi (Pilot, Ridgeline, Passport).

Also, liquid filled pressure tester in several Hondas

Check pressure in your spare tire.

Anyone have trouble with putting the spare on from a flat and lose the LKAS and forward brake assistance? Are whatever it’s called. Sounds like Honda doesn’t want non OEM rims on their vehicles.

All wheels need to be the same size for those systems to operate correctly. The spair is for emergency use only. Everything should return to normal once the road wheel/tire is reinstalled.
