How do you reset the tire pressure monitoring system on a honda odyssey 2011?

Answer 1

You don't RESET it per se. You make the air pressure in all four tires exactly equal to the tire pressure recommended on the metal placard that is located either on the driver's door or in the driver's door frame (and the tire pressure is also specified in the owner's manual). I do not remember the values, but if the metal placard says 32 psi FRONT and 31 PSI REAR, use a good, accurate tire gauge to get all the tires to that exact pressure, and the Tire Pressure Monitoring System warning light will go out.

If, on the other hand, one of your 4 TPMS sending units is bad, then you need to have a dealer or mechanic replace the bad one. That is, each wheel has a small electronic device that transmits by radio to the central computer, the tire pressure inside each of the four tires. The device is, naturally, inside the tire. It's about the size of a marble or a grape. So, in order to replace them, you need to remove the wheel from the vehicle, and then remove the tire from the metal rim.
