2007 Acura RL check engine

To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malfunction indicator lamp will
come on for 20 seconds. If it then
goes off, the readiness codes are set.
If it blinks five times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Refer to
for more
info rmation (see page ).
Your
vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics for the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If
this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION
SYSTEM’’ message on the multi-
info rmation display, it means one of
the engine’s emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle’s performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.If
the indicator comes on repeatedly,
even though it may go off as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. If the battery in your vehicle has
been disconnected or gone dead,
these codes are erased. It can take
several days of driving under various
conditions to set the codes again.
