General Information
Parts Marking
To deter vehicle theft, certain major components are marked with the vehicle identification number (VlN). Originalparts have self-adhesive labels. Replacement body parts have generic self-adhesive labels. The original engrne ortransmission VIN plate is transferred lo a replacement engine or transmission and attached with break-off bolts.
NOTE: Be careful not to damage the parts marking labels during body repair. Mask the labels before repairing the part.

Valve Guide Replacement
Special Tools Required. Valve guide driver, 5.5 mm 07742-0010100. Valve guide reamer, 5.5 mm 07HAH-PJ7o108
1.Inspect valve stem-to-guide clearance (see page 6-
32t.
As illustrated below, use a commercially available
air-impact valve guide driver (A) modified to fit the
diameter of the valve guides. In most cases, the
same procedure can be done using the special tool
and a conventional hammer.
10.8 mm{0.,|2 in.)
3. Select the proper replacement guides, and chill
lhem in the freezer section of a refriqerator for
about an hour.
4. Use a hot plate or oven to evenly heat the cylinder
head to 300'F (150"C). Monitor the temperature
with a cooking thermometer. Do not getthe head
hotterthan 300'F (150"C); excessive heat may
loosen the valve seats.

7.
Working from the camshaft side. use the driver and
an aar hammerto drive the guide about 2 mm (0.1
in.)towards the combustion chamber. This will
knock off some of the carbon and make removal
easier. Hold the air hammer directly in line with the
valve guide to prevent damaging the driver.
Turn lhe head over, and drive the guide out toward
the camshaft side of the head.
lf a valve guide won't move, drill it out with a I mm
(5/16 inch) bit. then try again. Drill guides only in
extreme cases;you could damage the cylinder
head if the guide breaks.
Remove the new guide(s) from the freezer, one at a
time, as vou need them.

General Troubleshooting Information
Intermittent Failures
The term "intermittent failure" means a svstem mav
have had a failure. but it checks OK now. lf the
Malfunction Indicator Lamp (MlL) on the dash does not
come on, check for Door connections or loose terminals
at all connectors related to the circuit that Vou are
troubleshooting.
Opens and Shorts
"Ooen" and "Short" are common electrical terms. An
open is a break in a wire or at a connection. A short is
an accidental connection of a wire to ground or to
another wire. In simple electronics, this usually means
something won't work at all. With complex electronics(such as ECMs)this can sometimes mean something
works, but not the way it's supposed to.
How to Use the PGM Tester or a Scan Tool
lf the MIL {Malfunction Indicator Lamp} has come on
'1. Start the engine and check the MIL {A).
NOTE: lf the ignition switch is turned ON (ll), and
the engine is not started, the MIL will stay on for
15 20 seconds (see page 11-46).
K-> ;"PN/.- -::: - -d V-: !
w:ix&K#
2. lf the MIL stays on, connect the Honda PGM Tester(A) or an OBD ll scan tool to the Data Link
Connector {DLC) (B) located under the driver's side
of the dashboard.
3.
5.
Turn the ignition switch ON (ll).
Check the Diagnostic Trouble Code (DTC) and note
it. Also check the freeze data. Refer to the DTC
Troubleshooting Index, and begin the appropriate
troubleshooting procedure.
lf you do not find any DTCS, go to MIL circuit
troubleshooting (see page 11-97).
NOTE:. Freeze data indicates the engine conditions when the
first malfunction, misfire, or fuel trim malfunction
was detected.. The scan tool and the Honda PGM Tester can read the
DTC, freeze data, current data, and other Engine
Control l\4odule {EClvl) data.. For specific operations, refer to the user's manual
that came with the scan tool or Honda PG l\4 Tester.
lf the MIL did not stay
lf the MIL did not come on but there is a driveability
problem, refer to the Symptom Troubleshooting Index
in this section.
lf you can't duplicate the DTC
Some of the troubleshooting in this section requires
you to reset the ECM and try to duplicate the DTC. lf rhe
problem is intermittent and you can't duplicate the code,
do not continue through the procedure. To do so will
only result in confusion and, possibly, a needlessly
replaced ECM.
