tire pressure light won't turn off even
0:02
after you aired up the tires that's your
0:04
TPMS acting up short for tire pressure
0:06
monitoring system and yeah it can be
0:08
stubborn sometimes hey I'm Tom from Car
0:12
Justify i've seen folks top off their
0:13
tires and still drive around with that
0:15
little orange light staring them down
0:17
let's fix that today step by step first
0:20
thing make sure all four tires are
0:22
actually at the right pressure don't
0:24
just guess use a proper gauge and check
0:26
each one including the spare if your car
0:29
monitors that too you'll find the
0:31
correct pressures on the sticker inside
0:32
the driver's door once the pressures are
0:35
correct some cars will turn the light
0:37
off automatically after a few miles of
0:39
driving but if yours doesn't it probably
0:43
depending on your make and model there's
0:45
usually a reset button look under the
0:47
dash near the steering column or
0:49
sometimes in the glove box it's usually
0:51
labeled TPMS or has a little tire icon
0:55
turn the key to the on position but
0:57
don't start the engine hold that button
0:59
down until the TPMS light blinks slowly
1:01
a few times then release it after that
1:04
drive the car for about 10 to 20 minutes
1:06
at a steady speed to let the system
1:09
now if your car has a touchcreen like
1:11
newer Hondas or Toyotas the reset is
1:13
done through the menu go to settings
1:15
then vehicle settings and look for tire
1:17
pressure reset or initialize TPMS
1:22
still got the light you might be dealing
1:23
with a dead or weak sensor inside one of
1:25
the wheels each sensor runs on a tiny
1:27
battery and once that dies the system
1:29
can't read pressure from that tire
1:32
scan tools that read TPMS can tell you
1:34
which sensor isn't responding some tire
1:36
shops or auto parts stores will scan it
1:38
for free or you can pick up a handheld
1:40
TPMS tool if you want to DIY
1:44
and keep this in mind if you recently
1:46
rotated tires changed wheels or had a
1:48
flat repaired sometimes the system just
1:50
needs to relearn which sensor is where
1:52
some cars do this automatically others
1:55
need to be told through a relearn
1:58
so here's the recap check all your tire
2:00
pressures with a gauge look for the
2:02
reset button or screen option and drive
2:04
a few miles to complete the process if
2:06
the light stays on it's time to scan for
2:10
if this helped you knock that warning
2:12
off your dash go ahead and hit like and
