Was driving along today and the low tire pressure light came on... which annoying because it won’t say what tire it’s for.. so I stopped and checked all 4 tires and they were all roughly around 35lbs or pressure which is what’s required. But warning light fired up again. Anyone have issues with this yet?

I had the same thing happen to me a few days after I bought my car and I was on a small road trip. I freaked out thinking I already got a flat (coming from a 16’ sport that I got multiple flats/blowouts in) but I pulled over and checked and all 4 tires were at 35psi. I re set the tpms and it’s been fine ever since. No clue why it did that but it’s seems to be happening to a bunch of people.
 
You guys that are getting the false warnings, are you checking your tire pressure when it's cold and setting the pressure to 33psi (I believe), with a quality tire gauge, on all four tires per the info on the driver's door jam? Then resetting the tire calibration on your vehicle settings screen?

We also have a 2017 CR-V with the same TPMS and we don't get any false warnings once the pressure was correctly set.

On the 2018 Accord, I set my tire pressure once after I brought the car home, haven't had any issues since. Just wondering why some owners are having a problem with TMPS, most likely cause would be user error.
 
From the manual,

"...When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly..."
 
Since it's an indirect monitoring system, maybe, in winter, if one wheel is slipping enough in the snow, the system might detect that as a low pressure condition? Just doesn't make much sense otherwise, since the system is indirect, it's measuring and comparing wheel rotations between all four tires, when it sees one tire rotating less than the others, it will throw an error.

So, there are probably situations when this will occur, however, if the driver is not starting with the pressures correctly set, and the system correctly calibrated, it may be more problematic.

Yes. 9th gen similar.

I had a similar experience. TPMS light came on when i drove the car home this past Friday for an extended test drive, conditions were dry and cool. I stopped at a couple of gas stations trying to find one with a functioning air setup with pressure reading. All 4 tires were roughly the same, but were inflated to 40psi. I ran the TPMS calibration and continued to drive home. It came back on during the drive.

Once I got home, I reduced all pressures to 33psi (and reset the TPMS again), and I haven't seen the warning come back this week.
 
I've had the problem multiple times on the Touring 2.0T. At least for me I must recalibrate, get the warning again, recalibrate and then it's ok for awhile. Yes, I check the tire pressure and all were within 1 PSI of each other the times this has happened.

I bought my car yesterday, drove it around town doing stuff. About 3 hours later on the drive home my sensor came on. After about hour n half i went out and checked the pressure, 2 fronts were 34 driver rear 32/33, and pass rear 31.

I will check then this morning when I finally get up n about and see what they are.if anything Im assuming its because that 1 tire is at 31?

It was a bummer when it happened I immediately thought I had a flat and i was scrambling thru the tach looking for the screen to tell me the pressures on each tire only to find nothing. It was so nice to have that feature in my truck.
 
That tire pressure sensor used to constantly go off in my 2004 / 2006 / 2013 Si’s dash. It was only low about 50% of the time or perhaps my tires always had a bunch of slow leaks. I just got my first sensor warning on the Accord after about 750 miles. I put my thumb to each sidewall, hard as a rock on all four. I almost wish they just had a way to turn that sensor off and I’ll just monitor my own tire pressure. These cars simply have too many false alarms on this.
 
60 miles after I bought my first 2018 Accord, the low tire pressure warning appeared although all tire pressures were correct. I recalibrated the TPMS.

Just a few miles after I bought my second 2018 Accord, the low tire pressure warning appeared. One tire was indeed low. I reinflated it and recalibrated the TPMS. The warning has not returned in a week nor has that tire lost pressure.

I highly suspect most of these "false" low tire pressure warnings are the result of two things:

1) Dealers not properly performing the pre-delivery and final inspections (even though they check off the boxes indicating the tire pressures were checked/adjusted and the TPMS was recalibrated). I find evidence of this all the time.

2) Owners/mechanics not recalibrating the TPMS after adjusting tire pressure or rotating the tires.

I've owned several vehicles with indirect tire pressure monitoring systems since my first one (a 1999 Buick Regal) and never had any false warnings after properly inflating the tires and recalibrating the TPMS. Almost everyone else I know seems to battle low tire pressure warnings regularly.

If during the PDI they actually drove the car around like it says too in the OM to recalibrate, that would put those precious virgin miles on before you get your hands on the car. I think this is correct.

Of course unless the calibration can be overruled by a simple update to the TPMS system that is.
 
I had the same thing happen on the third day I owned the car. The TPMS was supposed to be reset/recalibrated by the dealer in their final inspection but was not done. I was freaking out on my first long drive in the car. Just go into your system and recalibrate the TPMS on your touchscreen and everything will be fine. It’s just one of the small details overlooked by the large volume car dealers.
 
I was having the low tire alert almost dailey I spoke to my dealer and he said that driving on gravel roads could also trigger the error. I have a mile of gravel to get to main road from my house .

They recommended doing a " master reset " in which you do the recalibration 3 times in a row without driving

I have not had the problem in over two months now

The gravel part makes total sense. If the tires slip it spins faster than the rest and sets off the TPMS.

"master" reset though means what?

You hit the TPMS button three times in a row or three engine starts in a row?

If you would, please expand on how to perform the "master reset"

TIA
 
For those of you who are experiencing recurring "false" TPMS alerts, do you still have the factory wheels and tires or have they been replaced by the larger accessory wheels or different aftermarket wheels/tires?

I can't find anything in the service information about a "master reset" for the TPMS, but there are two "calibration" procedures listed. One of these is the TPMS calibration performed through the audio system. The other must be done by the dealer using the HDS following the installation of accessory wheels.

The Accord's TPMS doesn't just look for differences in rotation speed, it also "listens" to the tires to detect differences in peak resonance frequency which decreases with tire pressure and is corrected based on the outside air temperature.

Is that for the 10th gens or do the 9th gens do the same with the resonance frequency of the tire!

Never heard of that during all the time I've owned the 2013 and read about that system.

Changing tires to snows and steelies (+1) would affect the resonance I would guess on the 9th gens. Never had that problem.

Just curious.

TIA
