sensor Acura TSX 2007 Owner's Guide

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on. Although
your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
sp ecified on the vehicle placard and
intheowner’smanual(seepage ).
Driving on a significantly under-
inflated tire causes the tire to
ov erheat and can lead to tire failure.
Under-infl ation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability. When
the low tire pressure indicator
is on, one or more of your tires is
signifi cantly underinflated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle’s tire information placard.
With this indicator on, you will see
which tire is losing the pressure on
the multi-inf ormation display along
with a ‘‘CHECK TIRE PRESSURE’’
message (see page ).

Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Havetheflattirerepairedbyyour
dealer as soon as possible.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
After
you replace the flat tire with
the spare, the low tire pressure
indicator stays on. This is normal;
the system is not monitoring the
spare tire pressure. Manually check
the spare tire pressure to be sure it
is correct.
If
you have a flat tire, the low tire
indicator and tire pressure monitor
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ).
If there is a problem with the TPMS,
the multi-information display shows
a ‘‘CHECK TPMS SYSTEM’’
message.

The floor mats that came with your
vehicle hook over f loor mat anchors.
This keeps the f loor mats f rom
sliding f orward/rearward and
possibly interf ering with the pedals
or making the f ront passenger’s
weight sensor’s inef f ective.
Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.
If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air dry bef ore
you use the vehicle. Seat Belts Floor Mats

If you use a non-Acura f loor mat,
make sure it f its properly and that it
canbeusedwiththefloormat
anchor. Do not put additional f loor
mats on top of the anchored mat.
Make sure the rear f loor mats are
properly hooked to the f loor mat
anchors. Your vehicle is equipped
with f ront passenger’s seat weight
sensors. If the rear passenger’s f loor
mat is on the seat rail of the front
passenger’s seat, the sensors will
detect the decreased weight on the
seat, and they may not work properly. This f ilter removes the dust and
pollenthatisbroughtinfromthe
outside through the climate control
system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the f low f rom

The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion. The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
systems work together to control the
engine’s combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection. It has three
subsystems: air intake, engine
control, and f uel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. It
then controls how much f uel to inject under all operating conditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.2
