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 and throttle opener.
2. INSPECT THROTTLE BODY
(a) Disconnect the throttle opener vacuum hose from the
throttle body.
(b) Apply vacuum to the throttle opener.
(c) Check that there is no clearance between the throttle stop
screw and throttle lever when the throttle valve is fully
closed.
(d) Reconnect the throttle opener vacuum hose to the throttle
body.
3. INSPECT THROTTLE POSITION SENSOR

INSTALLATION
1. INSTALL THROTTLE BODY
(a) Connect the water bypass hose (from the water bypass
pipe) to the throttle body.
(b) Connect the water bypass hose (from the water outlet) to
the throttle body.
(c) California:
Connect the air hose (from the intake manifold) for air as-
sist system to the throttle body.
(d) Install a new gasket and the throttle body with the 3 bolts.
Torque: 19 N´m (195 kgf´cm, 14 ft´lbf)
(e) Connect the 2 vacuum hoses to the throttle body.
(f) Connect the throttle position sensor connector.
(g) Connect the IAC valve connector.
2. CONNECT ACCELERATOR CABLE TO THROTTLE
BODY
3. A/T:
CONNECT THROTTLE CABLE TO THROTTLE BODY

IDLE AIR CONTROL (IAC) VALVE
ON±VEHICLE INSPECTION
1. INSPECT IAC VALVE OPERATION
(a) Initial conditions:
Engine at normal operating temperature
Idle speed set correctly
Transmission in neutral position
(b) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
(c) After the engine speed is kept at 900 ± 1,300 rpm for 5 se-
conds, check that it returns to idle speed.
If the engine speed operation is not as specified, check the IAC
valve, wiring and ECM.
(d) Remove the SST from the DLC1.
SST 09843±18020
2. INSPECT IAC VALVE RESISTANCE
NOTICE:
ºColdº and ºHotº in these sentences express the tempera-
ture of the coils themselves. ºColdº is from ±10°C (14°F) to
50°C (122°F) and ºHotº is from 50°C (122°F) to 100°C
(212°F).
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal +B and other terminals (ISCC, ISCO).
Resistance:
Cold17.0 ± 24.5 W
Hot21.5 ± 28.5 W
If the resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.

INSPECTION
INSPECT IAC VALVE OPERATION
(a) Connect the positive (+) lead from the battery to terminal
+B and negative (±) lead to terminal ISCC, and check that
the valve is closed.
(b) Connect the positive (+) lead from the battery to terminal
+B and negative (±) lead to terminal ISCO, and check that
the valve is open.
If operation is not as specified, replace the IAC valve.
