THROTTLE BODY
ON−VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) w/ EGR:
Check the vacuum at each port.
Start the engine.
Check the vacuum with your finger.

2. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Disconnect the sensor connector.
(c) Using an ohmmeter, measure the resistance between
each terminal.

3. REMOVE AIR CLEANER HOSE
4. DISCONNECT THROTTLE POSITION SENSOR CON-
NECTOR
5. DISCONNECT IAC VALVE CONNECTOR
6. REMOVE THROTTLE BODY
(a) Disconnect these vacuum hoses from the throttle body:
(1) Vacuum hose of throttle opener
(2) w/ EGR:
Vacuum hose (from port R of EGR vacuum modula-
tor)
(3) w/ EGR:
Vacuum hose (from port E of EGR vacuum modula-
tor)

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 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.
Throttle valve fully closed angle: 10°
3. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Insert a thickness gauge between the throttle stop screw
and stop lever.
(c) Using an ohmmeter, measure the resistance between
each terminal.

4. IF NECESSARY, ADJUST THROTTLE POSITION SEN-
SOR
(a) Loosen the 2 set screws of the sensor.
(b) Apply vacuum to the throttle opener.
(c) Insert a 0.43 mm (0.017 in.) thickness gauge, between
the throttle stop screw and stop lever.
(d) Connect the test probe of an ohmmeter to the terminals
IDL and E2 of the sensor.
(e) Gradually turn the sensor clockwise until the ohmmeter
deflects, and secure it with the 2 set screws.
