Just got this warning during a trip this weekend. Checked tire pressure which was 36 psi for all. Thought it was due to the weather getting colder but didn't make sense since it happened in the middle of about 100mi trip. Stayed that way for a couple days even after putting a little more air in each tire. Recalibrated after reading this forum and now the low tire pressure warning is gone. Thanks.
Tpms light. New car driven only 600 miles.

I am getting winter tire install today and trying to understand the calibration for TPMS, according to the manual, it said to enter the following menu and start the process, Vechicle-TPMS Calibration-Calibrate, and it said it requires cumulative 30 minutes of driving with speed between 30-65mph (48-105kph). My question is if I start the process and drive say 10 minutes and then turn off the car. Do I have to start the (menu) process over again every time until I get 30 minutes of drive time at speed? Or does the car know I am in the middle of the calibration process and will do the calibration automatically each time I drive the car without me going into the menu setting and start the calibrate process? Thanks in advance

I think it says in the TPMS commentary part of the manual ( the right side of each page) that the calibration process will continue. It says that if you stop the vehicle for 45 seconds the TPMS light may come on. It also says that it is normal, for the light to come on, and says that it means the process is not yet complete. So I would not recalibrate again unless the light doesn't go off after 30 minutes of driving.

Clarity is no different than any other Honda for TPMS calibration. READ THE MANUAL, and follow it to the letter. Yes it is very specific, yes it is archaic compared to other manufacturers who actually use pressure sensors, and yes it requires driving a fairly notable distance to complete the calibration, and yes it also requires you to us a good tire gauge to set tall the pressures manually first. It is completely irrelevant if you start calibration at 20 psi or 50 psi...the system will simply acknowledge that whatever pressure you us is "correct" even if it is wrong...so make darn sure you manually set them first to the CORRECT pressure you want to run, immediately before starting the calibration sequence and going for a good long drive to allow it to complete.
And entering winter is the typical time that everyone's light pops on, because tire pressure drops with colder temps and you need to add air.
Loosely explained the TPMS is measuring the diameter of the tires based on RPM of each tire. Lower pressure causes the diameter to shrink slightly, therefore the RPM of the tire to increase slightly. If the computer senses this as you drive, it turns the light on, basically telling you to check all of your tires for a potential problem. It's frankly a pretty lousy system, but that's how Honda rolls in this regard.

I'm probably in the minority with my feelings on this. I had the same issue with the over-inflated tires (about 55lbs). Didn't find it until had driven the car a few hundred miles. Honda dealers should definitely do better than this. When I lowered the pressure, I had to re-calibrate two separate times to get the TPMS light to stay off. That said, I do miss seeing the actual pressure in the tires like true TPMS would yield, but I think I'll trade that for not having to deal with the TPMS sensors in the wheels that have to be re-calibrated whenever you rotate tires or have to be replaced eventually (batteries fail in them). It also makes the replacement of wheels less painful/expensive. I see it as a little of a give and a get....
We just spent $200 to replace another troublesome pressure sensor inside the tire of our 2010 Insight. I'm so happy our Clarity uses the "archaic" TPMS system that doesn't involve these unreliable sensors (your car's sensors may vary).

I added an external TMPS sensors that replaces the valve caps.. After a week of owning the car, I sliced a tire by hitting a curb. It was at very low speed so I wasn't sure if I had done any damage. Drove for a couple of minutes (10-15 mph) and pulled over to check if I had done any damage to the rim. Low and behold the tire was almost flat. TMPS sensor never went off since I was driving at a low speed.
