lgnition Timing Inspection
1.
4.
5.
Connect the Honda PGM Tester to the data link
connector (DTC), and check for DTC'S. lf a DTC is
present, diagnose and repair the cause before
inspecting the ignition timing.
Startthe engine. Hold the engine at 3,000 rpm with
no load (in Neutral) until the radiator fan comes on,
then let it idle.
Check the idle speed (see page 11-138).
Follow the tester's prompts in the "SCS" menu
{see the tester operator's manual),
Connect the timing light to the service loop.
o
6. Point the light toward the pointer (A) on the cam
chain case. Check the ignition timing under no load
conditions: headlights, blower fan. rear window
defogger, and air conditioner are not operaling. lf
the ignition timing differs from the specification,
and there are no engine control module {ECM)DTcs,
replace the ECM (see page 11-4)

6. Start the engine. Hold the engine at 3,000 rpm with
no load (in Neutral) until the radiator fan comes on,
then let it idle.
7. Raise the engine speed to 2,000 rpm, and hold it
there.
8. Turn the headlights (high beam) on, and measure
voltage at the under-hood fuse/relay box terminal.
ls the voltage between 13.9 and 15.1 v?
YES-Go to step 9.
NO Repair or replace the alternator components
(see page 4-30).1
9. Read the amperage at '13.5 V.
NOTE: Adjust the voltage by turning the blower
motor, rear window defogger, brake lights. etc. ON.
ls the amperage 604 ot morc?
YES-Alternator/regulator operation is OK. I

Alternator Control System Test
NOTE: After troubleshooting, perform the engine
control module (ECM) idle learn procedure (see page
11-139).
1 . Check for proper operation of the electrical load
detector (ELD) by checking the malfunction
indicator lamp (MlL) (see page 1 l-3). lf a DTC is
present, diagnose and repair the cause before
continuing with this test.
2. Disconnect the engine wire harness 6P connector
from the starter sub harness 6P connector.
3. Start the engine, and turn the headlights (high
beam) ON,
4. Measure voltage between the engine wire harness
6P connector terminal No. 2 and the positive
terminal of lhe battery.

Valves, Springs, and Valve Seals Installation
Special Tools Required
Valve spring compressor attachment 07VAE-00101 0A
1. Coat the valve stems with engine oil. lnstall the
valves in the valve guides.
2. Check that the valves move up and down smoothly.
Installthe spring seats on the cylinder head.
Install the new valve seals (A) using the valve guide
seal installer (B).
NOTE: The exhaust valve seal (C) has a black spring(D), and the intake valve seal (E) has a white spring(F). They are not interchangeable.
6.
lnstallthe valve spring. Place the end ofthe valve
spring with closely wound coils toward the cylinder
n eao.
Install the valve retainer.
Installthe valve spring compressor, Compress the
spring, and install the valve keepers. Remove the
valve spring compressor.
Lightly tap the end of each valve stem two or three
times with a plastic mallet (A) to ensure proper
seating of the valve and valve keepers. Tap the
valve stem only along its axis so you do not bend
the stem.

Engine Oil Filter (3/4-turn type)
1. Remove the oil filterwiththesDecial tool.
2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter
clockwise with the special tool.
Tighten: 3/4 turn clockwise.
Tightening torque: 12 N.m (r.2 kgf.m,8.7 lbf.ft)

5. lf 4 numbers or marks (1 to 4 or V to VVVV) are
printed around the outside of the filter, use the
following procedure to tighten the filter.
. Spin the filter on until its seal lightly seats against
the block, and note which number or mark is at
the bottom.. Tighten the filter by turning it clockwise 3
numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.
