hey there car owners today I'm diving
0:02
into a super important topic that you
0:05
definitely don't want to ignore the
0:07
check emission system light on your
0:08
dashboard if that lights on don't just
0:11
shrug it off it's more than just a minor
0:13
annoyance it's a warning signal that
0:15
could save you a heap of trouble down
0:17
the road first off what's the deal with
0:19
this light well it's all about your
0:21
car's emissions control system which
0:22
helps reduce those nasty pollutants
0:25
ignoring it not a good idea it could
0:28
damage your engine reduce fuel effic and
0:30
lead to some seriously costly repairs so
0:32
what triggers this light let's break it
0:34
down one common cause is a loose or
0:37
damaged gas cap yep something as simple
0:39
as that if it's not tight or if it's
0:41
cracked fuel Vapors can leak and Trigger
0:43
the sensor so make sure your gas cap is
0:46
snug and check for any damage next up
0:48
the oxygen sensor this little guy
0:50
monitors the amount of oxygen in your
0:52
exhaust if it's faulty your engine might
0:54
burn fuel inefficiently upping emissions
0:57
and lowering performance then there's
0:59
the catalytic inverter its job is to
1:01
reduce harmful gases if it's clogged or
1:04
damaged your car won't meet emission
1:05
standards and you could be looking at
1:07
more serious engine trouble and let's
1:09
not forget the mass airf flow sensor
1:12
this sensor keeps the air fuel mixture
1:13
in check a problem here can mess with
1:16
your performance fuel economy and
1:18
Emissions so what happens if you ignore
1:20
the light well for starters reduced fuel
1:23
economy your car might start guzzling
1:25
more fuel than necessary you could also
1:27
face performance issues like rough
1:29
idling stalling or poor acceleration and
1:33
if you've got mandatory emission tests
1:34
in your area you're definitely not
1:36
passing with that light on so what
1:38
should you do start by checking the gas
1:41
cap tighten it and see if that helps if
1:44
not it's time to visit a mechanic to
1:46
diagnose the issue don't delay repairs
1:49
some problems can escalate and damage
1:51
expensive components like the catalytic
1:53
converter maintaining your emission
1:55
system isn't just good for your car it's
1:58
better for the environment and your
2:00
so the next time you see that check
2:02
emission system light take action before
2:04
it's too late thanks for watching stay
2:06
safe and keep those engines running
