To provide a short answer to your question, yes, this is true. The new system actually uses two methods to determine tire pressure indirectly, and your post describes one of them.
This is exciting from the perspective of being able to run aftermarket wheels without purchasing TPMS sensors. This introduces potential headaches on other fronts, however.
I downloaded the owner's manual as a PDF from the Honda Owner's web site. No, I don't own a 2013 yet, I just pretended I did. :)
The 2013 Accord does NOT use a pressure TPMS sensor like the older Accords.
The following is from the owner's manual"
From 2013 Accord Owner's Manual: TPMS (Tire Pressure Monitoring System)
Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will cause the low tire pressure/TPMS indicator to
come on and a message to appear on the multi-information display*.
This is the step in the right direction; old system was causing too many problems/false alarms. Nothing beats just quick glance at the tires before getting into the car
I wonder how effective this method is. My LX is about a week old, and I swear the front/driver side tire looks a bit low. I am assuming the dealer checked all that before handing the car over, but I'm tempted to break out the ol tire gauge.
This is kinda off topic but I purchased a set of 2013 Accord Sport model wheels online, and when I received them, 2 of the 4 wheels had the core to the standard valve stem taken out so there was no air in the tire at all. I was told that all I needed was to go to an automotive store and just purchase the core for the stems for a few bucks and inflate them. They said I didn't have to get them re-balanced because the tire didn't come off the wheel...does that sound right?
