BRAKE PEDAL
ON−VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
167.5 − 177.5 mm (6.594 − 6.988 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Disconnect the connector from the stop light switch.
(b) Loosen the stop light switch lock nut and remove the stop
light switch.
(c) Loosen the push rod lock nut.
(d) Adjust the pedal height by turning the pedal push rod.
(e) Tighten the push rod lock nut. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(f) Install the stop light switch and turn it until it lightly con-
tacts the pedal stopper.
(g) Turn the stop light switch back one turn.
(h) Check the clearance (A) between the stop light switch and pedal.
Clearance: 0.5 − 2.4 mm (0.020 − 0.094 in.)
(i) Tighten the stop light switch lock nut.
(j) Connect the connector to the stop light switch.
(k) Check that the stop lights come on when the brake pedal
is depressed, and go off when the brake pedal is re-
leased.
(l) earance (A) between the stop light switch and the pedal
stopper has been adjusted correctly, the pedal freeplay
will meet the specifications.
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the beginning of the se- cond resistance is felt. Measure the distance.
Pedal freeplay: 3 − 6 mm (0.12 − 0.24 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 3 − 6 mm (0.12 − 0.24 in.)
at the pedal.

THROTTLE BODY
ON−VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at each port.
Start the engine.
Check the vacuum with your finger.
Port nameAt idleAt 3,500 rpm
PNo vacuumVacuum
ENo vacuumVacuum
RNo vacuumVacuum
2. INSPECT THROTTLE POSITION (TP) SENSOR
(a) Disconnect the TP sensor connector.
(b) Apply vacuum to the throttle opener.
(c) Using an ohmmeter, measure the resistance between
each terminal.

(d) Reconnect the TP sensor connector.
3. INSPECT AND ADJUST DASHPOT
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check the idle speed.
Idle speed: 650 ± 50 rpm (N position)
(c) Open the throttle valve until the throttle lever separates from the dashpot end.
(d) Release the throttle valve gradually, and check the dash-
pot setting speed when the throttle lever touched the
dashpot end.
Dashpot setting speed: 2,200 ± 300 rpm

If not as specified, adjust using the following procedure:
(1) Stop the engine.
(2) Loosen the lock nut of the stopper bolt.
(3) Adjust the dashpot setting speed by turning thestopper bolt.
(4) Start the engine and check the dashpot setting speed.
(5) Retighten the lock nut.
(e) Maintain the engine at 3,500 rpm.
(f) Release the throttle valve, and check that the engine re- turns to idle in a few seconds.
4. CHECK THROTTLE OPENER
(a) Disconnect the vacuum hose from the throttle opener, and plug the hose end.
(b) Check the throttle opener setting speed. Throttle opener setting speed: 700 − 1,000 rpm
If the throttle opener setting is not as specified, replace the
throttle body.
(c) Stop the engine.
(d) Reconnect the vacuum hose to the throttle opener.
(e) Start the engine, and check that the idle speed returns to the correct speed.
Idle speed: 650 ± 50 rpm (N position)

INSPECTION
1. CLEAN THROTTLE BODY
(a) Using a soft brush and carburetor cleaner, clean the cast parts.
(b) Using compressed air, clean all the passages and aper- tures.
NOTICE:
To prevent deterioration, do not clean the throttle position
sensor, dashpot and IAC valve.
2. INSPECT THROTTLE VALVE
(a) Apply vacuum to the throttle opener.
(b) Check that there is no clearance between the throttle stop
screw and throttle lever when the throttle valve is fully
closed.
3. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Insert a 0.50 mm (0.020 in.) or 0.75 mm (0.030 in.) feeler
gauge between the throttle stop screw and stop lever.
(c) Using an ohmmeter, measure the resistance between
each terminal.
