2012 Acura TL sensor

µ
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.
Check the terminals f or corrosion (a
white or yellowish powder) af ter
removing all engine compartment
covers (see page ). To remove
corrosion, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f urther corrosion.
If additional battery maintenance is
needed, see your Acura dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
The sensor on the negative terminal
monitors your vehicle’s battery
condition.
If there is a problem with the sensor,
you will see a ‘‘CHECK BATTERY
SENSOR’’ message on the multi-
inf ormation display. Have the vehicle
checked by your dealer.
To see the battery label, remove the
lef t side engine compartment cover
(see page ).

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.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
qualitypartsmayincreasethe
emissions f rom your vehicle.
The 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.
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. The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the fuel This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
