2004 Acura TSX check engine light

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. If it comes on
at any other time, it indicates one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your car’s perf ormance, it can
reduce your f uel economy and cause
your car to put out excessive
emissions. Continued operation may
cause serious damage.Youshouldalsohavethedealer
inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.
This indicator may also come on
along with the ‘‘D’’ indicator.
If you have recently ref ueled your
car, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks at least
three times. Replace the f uel f ill cap
if it is missing. Tightening the cap
will not make the indicator turn of f
immediately; it takes at least three
days of normal driving.
If the indicator remains on past three
days of normal driving, or the f uel
cap was not loose or missing, have
the car checked by the dealer as
soon as possible. Drive moderately
until the dealer has inspected the
problem. Avoid f ull-throttle
acceleration and driving at high
speed.
