Did you perform the TPMS calibration after adjusting the pressure?
Did you perform the TPMS calibration after adjusting the pressure?
My 2017 CRV was delivered with the tire pressure set to 44. I left them that way for about a week, and then set them to what the manual states.If I remember correctly it's 33 in the front tires and 32 in the rear.
You have to reset the TPMS for the error to clear.
I am not sure if anyone is 100% sure how Honda implemented the TPMS system in software. It looks for differences in tire rotation speed, so if one is different than the other three it would certainly go off. Since 19" rims can be put on the vehicle I would expect that it would not alert you if ALL the tires are inflated to 48 PSI. Yours did so that means that it can tell the difference.
To reset go to the head unit press the home BUTTON then SETTINGS the VEHICLE and at the top you will see TPMS Calibration. Press that and then press CALIBRATE. The warning indicator should come off of the Dash display.

Yes as I stated it does you the tire rotation speed but beyond that we know very little on how the specifics of the software is written to deal with that information. Your experience with it not normally going off with all tires at 44 PSI is what I would have expected, but the OP had a different experience. Maybe Honda tweaked the software for 2019.My 2017 CRV was delivered with the tire pressure set to 44. I left them that way for about a week, and then set them to what the manual states.
As for the TPMS, it is a system that monitors tire rotation speed on the newer Hondas. Which means it needs no special sensors in the tire like older models did, but it comes with a couple of quirks as well. One time my LKAS decided I was heading out of a lane on the Freeway (I wasn't but I was on a corner, so it over-reacted, as did LDW). And almost immediately after that I got a TPMS warning, so I pulled off the freeway to check tire pressure and they were all good.. so I simply hit the TPMS recalibration and drove off.. and the indicator light turned off and the system recalibrated with no more issues. I believe the recalibration will trigger TPMS to lock in the wheel speed represented by the current tire pressure, not some fixed number. Which begs the question as to how it deals with AWD and variations in wheel speed from the AWD doing what it is supposed to do.
With the newer TPMS... I do expect to get a false positive from time to time, though so far I only had the one. My wife had one early on with her 2018 Accord, which turned out to also be a false positive. Then later, TPMS warning for her Accord again, and this time it was correct as there was a slow leak from a nail. But the TPMS did not go off until the tire was nearly 10lbs low in pressure.... so I do question the service advisor stating that TPMS is sensitive to 3lbs to the original poster.
Did you recalibrate again after adjusting the pressures, and before you left?When we got to our destination, I did recalibrate the tpms. All was good, until we left for our trip home. Tire pressure was checked and adjusted before we left. About 30 minutes into our highway driving, the warning appeared again. Grr.
Unless your dealer took all the air out of the tires and pumped new air in, they should overinflate the tires a little bit to compensate for the warm/hot air alredy inside the tires. Common sense.Didn't read everything but I always calculate pressure when cold. 33psi cold front 30psi rear as is recommended on the door. Recently had tires rotated and the dealer said they were they were under inflated and inflated them to 35 psi all around. When I told the teenage tech they were over inflated, he looked at the door and said "My gosh, You're right." TPMS only tells me I have a problem with low pressure. Dealers always inflate. I don't know why.
I think they come from the factory that way, to try to void flat spotting while in transit. The dealer is supposed to lower the pressures to the recommended level during their pre-delivery inspection (PDI) but it seems many dealers do not...and this is not unique to Hondas either.Does anyone know why Honda dealers, seems to be all dealers around the U.S., inflate the tire pressure to over 40psi when the manual clearly indicates 33/30 as well as the door's sticker?
It gotta be a reason for that.
YUP - happened to me too. Luv being spoiled w/the Auto lights.Related, but off topic, when ever I take my vehicles into the dealer for service, (any brand!) they ALWAYS turn off the auto headlight setting, then leave it that way. I usually find out the first time i drive at night, and realize I don't have my headlights on. This is potentially a safety issue. The porter, or whoever brings the car up when you pick it up, should assure it is back in 'Auto" position before delivering the car back to the owner. I've now kinda trained myself to look at this whenever I get back my car before driving away. Rant off..
There is a setting which automatically turns on lights when wipers are onNever use Auto lights. Many times they don't come on when needed during daytime rain. Wipers on? Headlights on. The law in some southern states I think because of common summer T-Storms.
could be canadian featureHaven't found that one. In Canada only? Your daytime running light law certainly has been around for many years.
