When you rotate tires on a car with the pressure monitor, how does the
computer know that what was the front right is not the left rear?
Does the computer sensor know from what direction the signal is coming
The computer only knows the specific tire on 2006-and-under models. Those
vehicles had "initiator" type sensors that communicated with little
transponders above each wheel. Those transponders then talked to the TPMS
2007+ vehicles have "initiator-less" sensors. With this system, the
computer has no information on which specific tire is low. You must check
the pressure in /all/ tires, including the spare (if it has a sensor).
OK, I made a mistake.
I just checked Honda's Techinfo site ( https://techinfo.honda.com ). I used
not to be able to get access to this site because it was for US-only. This
meant I had to rely on other documentation, which was not always complete.
Well, now Techinfo is available to Canadians as well, so I have access to
more info than before.
So, the upshot is that it looks like...
MOST 2007+ Honda models have initiator-less TPMS. Higher-end models (e.g.:
Odyssey Touring) have initiator-type TPMS.
ALL Acura models with TPMS (except for Civic-based vehicles) have
Therefore, all (non-Civic) Acuras with TPMS are able to tell you
specifically which tire it is that's low, because they have a little
transponder above each specific wheel that communicates directly with the
sensor in that wheel.
American Honda does not market any Civic-based vehicles under its Acura
Canada's standard of living is lower, so Honda Canada needed to give its
Acura dealers a Civic-based car so they'd have something cheap to sell.
U.S. Acura dealers sold the RSX until the 2007 model year.
I thought the whole idea of the entry-level/near luxury vehicle was to
attract young buyers to a particular brand when they are young and keep
them as customers as they age and their income increases. For example
sell the person just out of university an RSX, then a TL several years
later, and finally an MDX or RL.
Now, I think a TSX starts around $30K U.S.
