1.After the engine starts, the lAc valve opens for a certain time. The amount of air is increased to raise the idle speed
about 150 - 300 rpm.
When the coolant temperature is tow, the IAC valve is opened to obtain the proper fast idle speed. The amount of
bypassed air is thus controlled in relation to the engine coolant temperature'

Troubleshooting
Reverse Gear Noise Reduction System
Whenever the clutch pedal is depressed to shift into reverse, the mainshaft continues to rotate because of its inertia.
The resulting speed difference between mainshaft and reverse idler gear produces gear noise.
The reverse gear noise reduction system employs a cam plate which was added to the reverse shift holder. When shifting
into reverse, the sth/reverse shjft piece, connected to the shift lever, rotates the cam plate. This causes the sth synchro set
to stop the rotating mainshaft. As there is no speed difference between mainshaft and reverse idler gear, there will be less
gear norse.
NOTE: This system is not a fully-synchronized gear noise reduction system.
Therefore, you may hear gear noise when
O you shift into reverse with the vehicle not yet completely stopped.
@ you shift quickly into reverse during fast idling.
-
Gear noise is oresent when shift-ing into reverce after the engineis started.
Test-drive the vehicle.

Measure the clearance between5th shift fork and 5th synchrosleeve {see page 13'26).
ls the clearance 1.0 mm (0.04
in) or less?
Measure the MBS shift piece pin(see page 13-27).
ls ( 6.8 mm (0.27 in) or more?Replace the MBS shift piece.

IRack Guide Adjustment
NOTE: Perform rack guide adjustment with the wheels
in the straight ahead Position.
1. Loosen the rack guide screw locknut with the
cialtool.
'96 - '97 models:
Loosen the rack guide screw
'98 - '00 models:
Remove the rack guide screw and remove the old
sealant off of the threaded section.
Apply new sealant all around the threads. Loosely
installthe rack guide screw
Tighten the rack guide screw to 25 N'm (2.5 kgf'm.
18 lbf.ft), then loosen it.
Retighten the rack guide screw to 3 9 N'm (0.4 kgim,
2.9 lbf.ft), then back it off to specified angle.
Specified Return Angle: 20" max.
Tighten the locknut while holding the rack guide
screw.
Check for tight or loose steering through the com-
plete turning travel.
Perform following insPections:
. Steering operation (see page 17-30).
. Power assist with vehicle parked.

Fluid Replacement
Check the reservoir at regular intervals, and add fluid as
necessary.
CAUTION: Always us€ Genuine Honda Power Stearing
Fluid-V or S. Using any other type of power sto€ring
tluid or automatic transmission lluid can cause
increased wear and poor steering in cold weathor.

LEVEL LINE
LOWER LEVEL LINE
1. Raise the reservoir, then disconnect the return nose.
2. Connect a hose of suitable diameter to the discon-
nected return hose, and put the hose end in a suit-
able container.
CAUTION: Take care not to spill tho fluid on the
body and parts. Wipe off any spill€d fluid at oncs'
3. Start the engine, let it run at idle, and turn the steer-
ing wheel from lock-to-lock several times When
fluid stops running out of the hose, shut off the
engine, Discard the fluid.
4. Reinstall the return hose on the reservoir'
5. Fill the reservoir to the upper level line.
6. Start the engine and run it at fast idle, then turn the
steering trom lock-to-lock several times to bleed air
trom the system.
7. Recheck the fluid level and add some it necessary.
CAUTION: Do not fill the reservoir beYond the
upper l€vel line.
