If the air intake duct is removed from the throttle body take great care to keep fingers away
from the throttle plate. The drive motor has very high torque and is capable of random move-
ment at any time. Do not under any circumstances activate the throttle plate by hand.
When removing the throttle body from the intake manifold disconnect the wiring first. During
replacement connect the wiring last.
Do not activate the throttle body using a DC suppy to test the motor,as permanent damage to
the throttle body will result.

HOW TO INITIALIZE A/T LEARNING VALUEM1231022600121
AIM
The use of EEPROM has enabled the A/T learned
value to be retained even after the battery terminals
are disconnected. However, the learned value should
be initialized if the A/T assembly, the engine assem-
bly, the valve body assembly or the solenoid valves
are replaced. The initialization procedure is as
below:
INITIALIZATION PROCEDURE
1. Shift the selector lever to the P range and turn the
ignition switch to the LOCK (OFF) position. Then,
connect the MUT-III to the diagnosis connector.
2. Initialize the learned value on the initialization
screen.
3. After this initialization, make the system learn the
idling in accordance with "Learning procedure for
idling in MPI engine" (Refer to GROUP 00

Precautions before Service 00-22).

STEP 1. Using diagnostic tool MB991958, check data list
item 7: Transmission Fluid Temperature Sensor.
To prevent damage to diagnostic tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting diagnostic tool
MB991958.
(1) Connect diagnostic tool MB991958 to the data link
connector.
(2) Start the engine.
(3) Set diagnostic tool MB991958 to the data reading mode.
Item 7: Transmission Fluid Temperature Sensor.
When the engine is cool: Diagnostic tool display is
almost equal to the ambient temperature (atmo-
spheric temperature)
NOTE: Set diagnostic tool MB991958 to the Engine
MPI data list reading mode for item number 5, Intake
Air Temperature (IAT) Sensor and note the tempera-
ture measurement. When the engine is cool, the
temperature should be almost equal to the ambient
temperature (atmospheric temperature), and the IAT
sensor measurement should be approximately the
same as the Transmission Fluid Temperature Sen-
sor.
When the engine is warm, at approximately running
temperature: 70
80C.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
