2006 HONDA PILOT check engine

If the malf unction indicator lamp
comes on along with the ‘‘D’’
indicator, there is a problem in the
automatic transmission control
system.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or 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 the battery in your vehicle has
been disconnected or gone dead,
these codes are erased. It
cantake
several days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive 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. Ref er to for more
inf ormation (see page ).
If you have recently ref ueled your
vehicle, the indicator could come on
because of a loose or missing f uel f ill
cap. You will also see a ‘‘CHECK
FUEL CAP’’ message on the
inf ormation display. Tighten the cap
until it clicks at least once.
Tightening the cap will not turn the
indicator turn of f immediately; it
can take several days of normal
driving.
If the indicator remains on or the
f uel cap was not loose or missing,
have the vehicle checked by the
dealer as soon as possible. If this indicator comes on
while driving, it means one
of the engine’s emission control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance,
continued operation may cause
serious damage.
