I had my tire pressure checked after the "Check tire pressure" message came up on my 2014 Honda Civic hybrid. Now the message won't turn off and my iPhone 6 will no longer pair with the system. I
I have less than 1400 miles on this car. I bought it new in 2014. I have never
had the issue before.
Be sure the pressure is correct per the tire rating (on side wall it has the pressure it should be filled too), fill to the correct pressure, Tire shops are only filling to about 32 psi while most car tires need 35 psi and anyone tire under 32 psi sets off the check tire pressure light on dash.
it is a little early for the tire pressure sensors to start failing, they usually go 7 to 10 years, so do what enginecreator suggested, make sure you use a good tire pressure gauge, if that doesn't turn off the TPMS light then you may have to reset the system and that procedure is listed in the owners manual. As far as the phone, my wife's did the same thing and had to have the phone replaced, something about a weak signal, but they also told us to make sure all the updates were done and then to power it down wait a minute or two then turn it back on and see if it would sync. Might be something to check.
Thank you! I appreciate it!
Hope it works out for you.
