Oxygen
Sensors

1996
and
later
engines
are
equipped
withmultiple
oxygen

sensors
.
See
Fig
.
21
.
A
regulating
sensor
is
mounted
before

each
catalytic
converter
and
amonitoring
sensor
downstream

of
each
converter
.
The
regulating
sensor
monitors
engine
com-

bustion
efficiency
and
helps
to
control
the
fuel
injection
system

and
exhaust
emissions
.
The
monitoring
sensor
is
usedby
the

On-board
diagnostic
system
to
monitor
the
function
of
the
cata-

lytic
converter
.

the
engine

control
module
(ECM)
to
monitor
the
oxygen
content
in

This
allows

for

not
recommend
tire
rotation
.
Due
to
the

sus-
pension
design,
the

Routine
maintenance
of
the

includes
maintain-

ing
the

checking
brakepads
for

wear,
checking
hand

for
fluid
leaks
or
other
damage
.

Check
that
brake
hoses
are
correctly
routed
to
avoidchafing

or
kinkíng
.
Inspect
unions
and
brake
calipers
for
signs
of
fluid

.
Inspect
rigid

or
other
damage
.

Inspect

WARNING
-

Incorrect
