How smart is the light, and how smart is the dealer?
(don't even ask how smart is the driver ok)
New Accord EX4 sedan about four months out of the dealer, haven't done
a thing yet but put gas in it and putter around town. Noticed the
TPMS light on, pulled over to look at the tires. Nothing obvious, so
I drove on. Next time, I looked carefully, maybe the right front was
a tad low?
Drove on down to the service station air pump, promised to buy some
gas if they'd turn on the coin-op air. Turns out that, warm, all four
tires were almost exactly 28psi. But my door panel suggests they
should be 32psi cold. Harump. I know my dealer has long had a habit
of underinflating when they adjust tires, why, I don't know. And I've
beem wondering why my MPG was a mile or two lower than on previous
Accords. Harump. So I blew them all up to about 32psi warm. Turned
the key, drove a block - light stayed on. Maybe a bad sensor, huh?
Had lunch, got back in - and now the light was off.
So, does it take a couple of samples to convince itself that the
pressure is OK? How the heck does the sensor work anyway?
