I had this issue on long trips, too. It went away when I replaced the OEM tires.

 

You'll need to perform a full reset on the TPMS assuming all of the tires have similar PSI values (meaning that a good mix would be 34, 34, 34, 35 and bad might be 34, 37, 39, 35) since we have a passive system that uses rotational rate to measure whether the pressures are below a limit.

Search on the board for the full reset procedure or search it on the G88gle using the term (site:fitfreak.net INSERT SEARCH TERM HERE).

 

Mine came on again last week on my 2017. Did the same thing last winter. Dealership says it's because the change in temperature. Pressure was fine.

 

theTPMS is more problem than good but is only a mandate from our wonderful Gov'mint...in some respects I yearn for the days of manual everything...at least when the part broke you knew what part it was and could replace it. My 1994 Civic VX was my ideal car - no power anything except for dealer installed A/C (at my request). It was the most reliable Honda I ever owned - IIRC only the mechanical thermostat failed me in the 11+ years I owned her (until she was stolen, parted out, and the shell left for dead on the other side of the City).

 

Went to the dealer this week with my 2018 and they said it could come on if the tires are over-inflated.

 

Are they just pulling your legs?

 

I routinely over inflate my tires to at least 35 all around and it doesn't trip the TPMS.

 

When I do it myself I use 35 psi, maybe just for convenience. With an oil change the servicer always uses the range posted on the door. I do not notice a difference, except when one tire had been below pressure.

 

Is this the silly Bosch system that reads the wheel speed sensors? I just picked up a 2008 Fit Sport and there is TPMS weirdness.

 

GKs don't have TPMS sensors in the wheels. They utilize the ABS system to calculate wheel speed.

 

I rather have this simple system than paying hundreds of dollars with new TPMS in my Porsche Turbo. The only reason I replaced them is because the dash warning will not reset until they are replaced. Going over road tar strips give me sufficient warning to check the tire pressure.

 

Nothing new to add to this thread, just another owner (2017 Fit) frustrated with the TPMS light illuminating for no good reason. Happened again yesterday and all 4 tires are at door spec pressures. My wife is the primary driver and no longer reacts when the TPMS light comes on and instead waits until she gets home for me to check it out. Pretty much renders the system useless.

OK, I feel better now.

Black electrical tape is the solution. I wasn't able to find a wiring diagram to enable a TPMS light delete feature - that's on my LT list of features to add. TPMS didn't exist before 20xx and people survived.
