THROTTLE BODY (THROTTLE VALVE AREA)
CLEANING
1. Remove the air intake hose from the throttle body.
2. Spray cleaning fluid on a clean cloth.
15 mm
3. Wipe off the dirt around the throttle valve with the cloth
sprayed with cleaning fluid.
15 mm
Caution
(1) Do not spray the cleaning fluid directly to the
throttle valve.
(2) Make sure the cleaning fluid does not enter the
motor from the bypass line. Also make sure it
does not enter the sensor through the shaft.
(3) Be careful not to rub off the molybden applied
around the throttle valve shaft.
4. Attach the air intake hose.
5. Adjust the basic idle speed. (Refer to P.13A-127.)

THROTTLE POSITION SENSOR ADJUSTMENT

1. Connect the MUT-II to the diagnosis connector.
When not using the MUT-II, proceed as follows:
(1) Disconnect the throttle position sensor connector, and
connect the special tool (test harness: MB991536)
between the disconnected connector taking care not
to confuse the terminal to be connected.
(2) Connect digital voltmeter between the terminal No.
2 and the terminal No. 4 of the throttle position sensor
connector.
2. Turn the ignition switch to "ON" position (but do not start
the engine).
3. Check the output voltage of the throttle position sensor.
Standard value: 535 - 735 mV
