2008 HONDA PILOT engine

If you take your vehicle f or an
emissions test shortly af ter the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain ‘‘readiness
codes’’ that must be set in the on-
board diagnostics f or the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions.
If the testing f acility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle f or retesting by
doing the f ollowing.Make sure the gas tank is nearly,
but not completely, f ull (around
3/4).
Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds.
Keep the vehicle in Park. Increase
the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
Make sure the vehicle has been
parked with the engine of f f or 6
hours or more.
Make sure the ambient
temperature is between 40° and
95°F. Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
f or at least 20 minutes. Drive on
the highway in D. Do not use the
cruise control. When traf f ic allows,
drive f or 90 seconds without
moving the accelerator pedal.
(Vehicle speed may vary slightly;
this is okay.) If you cannot do this
f or a continuous 90 seconds
because of traf f ic conditions, drive
f or at least 30 seconds, then repeat
it two more times (f or a total of 90
seconds).
Without touching the accelerator
pedal, let the engine idle f or 20
seconds.
