1 week into my new 10 generation 2.0 Touring and the TPMS light came on. Here is the back story and then a few questions.

Checked the tire pressure when the tires were cold and they were all over 40 psi. I checked the pressure as it is common practice for dealer to over inflate to improve ride quality. I did not recalibrate when letting air out of tires. Made a short trip around town and the TPMS light came on. Checked all 4 tires and pressure was 35. So here are my questions:

Is there a way to tell which tire is causing the TPMS light to activate? I tried looking at all the menus in the Vehicle Set up and could only find the TPMS Recalibration. (With all the "gingerbread" this car has it is hard to believe there is no way to determine which tire is low.)

When adjusting the tire pressure does one need to recalibrate the TPMS?

I posted a response to you on the other board which I will give here:

You must recalibrate the TPMS each time you adjust the tire pressure. It only takes a few seconds to do through the menus.

Right now the car thinks your 35 PSI is low because it is currently calibrated to be above 40. Recalibrating will tell the TPMS that 35 PSI is normal.

BTW, Welcome to this board. You should get more respectable responses from the members and moderators on this board.

KEYBOARD did not address your first question. As far as I know, the answer is no, there is no way to know which tire is low. In that regard, my ‘18 is the same as the TPMS on my my ‘10. I do have a weird malfunction on my ‘18. I get a false low pressure warning occasionally. Always happened after a long drive.

THANK YOU....With all the technology that this car has you would think that TPMS sensors would be included.

The only way to know is to check them with a good quality tire gauge. Every glove box should contain one. Dealers should give one, a good one, with every new car sold with their dealer contact information and the roadside assistance information printed on it but that’s a different thread.

First thing I did after I got it home from the dealer, to get ready for driving it around on a long weekend, was to check the tires. They were all over 40 PSI. Adjusted to the 33 PSI recommended on the driver side door post sticker. Ride improved a bit, not as hard as before. On the drive the TPMS went on. I had neglected to reset it hoping it was within range but 7+pounds wasn't. It took 2 tries but it turns out that it calibrates for several minutes as you drive after resetting. I checked the manual but the system doesn't discretely specify which tire. I think on the Acuras it does, even tells you what the tire pressure is.

A guy at the dealership told me that Honda decided not to include the individual sensors because they were being broken often by third party service centers. When people came in to say they were malfunctioning the owner of the car would then be out roughly $100 to replace them or they would have to fight with the third party service center.

I'm personally thinking they had to cut back on cost with all the other features they've included in the cars lately. It's a shame because I really like the way our '17 Pilot has the individual sensors and the Tire Fill Assist feature.

I for one find TPMS to be fairly unreliable, especially in the winter months. I've had to have them individually replaced exactly for the reason above (tire shop damage) and am relieved Honda decided to go with a central system instead.

I think they are most important in the winter months when tire pressures can go down from cold weather... I had my TPMS light come on three times within the first 900 miles... took it to my dealer who admitted to me that this system is a 'Pain in the ass'.
