Have you ever wanted to
know more about your auto repairs,

00:00:03.120 --> 00:00:05.280
but were afraid to
ask your mechanic?

00:00:05.280 --> 00:00:08.080
This brief video provides
you with information designed to

00:00:08.080 --> 00:00:11.145
help you make the right
decisions about your auto repairs.

00:00:11.685 --> 00:00:15.205
An oxygen or o two sensor is
an electronic device in your

00:00:15.205 --> 00:00:18.005
exhaust system that measures the
air fuel ratio in your

00:00:18.005 --> 00:00:21.260
engine. By sensing the amount
of oxygen in the exhaust,

00:00:21.260 --> 00:00:24.080
it helps the engine adjust the
amount of fuel that it consumes.

00:00:24.620 --> 00:00:27.180
To maintain a proper air
to fuel mixture in your engine,

00:00:27.180 --> 00:00:30.125
it's important that the
oxygen sensors are working properly.

00:00:30.125 --> 00:00:32.685
But if there is a sudden high
fuel consumption or you're

00:00:32.685 --> 00:00:34.285
having issues with
starting the car,

00:00:34.285 --> 00:00:37.090
chances are you need your
oxygen sensor checked.

00:00:37.090 --> 00:00:40.050
Replacing your o two
sensor is an inexpensive maintenance.

00:00:40.050 --> 00:00:42.770
But if left unchecked,
emissions, engine performance,

00:00:42.770 --> 00:00:46.235
and fuel efficiency will suffer.
And if ignored long enough,

00:00:46.235 --> 00:00:49.455
A catalytic converter can be damaged
and might need to be replaced.

00:00:53.550 --> 00:00:55.950
Faulty o two sensor
may cause a rough idle,

00:00:55.950 --> 00:00:57.650
but isn't a big safety concern.

00:01:00.955 --> 00:01:02.715
From an environmental
point of view,

00:01:02.715 --> 00:01:05.195
a new o two sensor
will not only save gas,

00:01:05.195 --> 00:01:06.495
but reduce air pollution.
