Electronic Throttle Control Actuator
Description
The throttle body is located on the intake manifold. It controls air into the intake manifold. The electronic throttle
control actuator consists of throttle control motor, throttle position sensor, etc. The throttle control motor is operated
by the Engine Control Module (ECM) and it opens and closes the throttle valve. The throttle position sensor detects
the throttle valve position.
Operation
Filtered air from the air cleaner enters the intake manifold through the throttle body. A throttle valve (plate) is used to
supply air for idle and driving conditions. The throttle position sensor is part the throttle body. The throttle position
sensor signal is used by the ECM to determine throttle position. The ECM controls the electronic throttle control to
meter air into the engine. This regulates engine power. The vehicle is in sense a “Drive by Wire” system.
Removal & Installation
1. Remove the engine cover.
2. Disconnect the negative battery cable.

3. Disconnect the electronic throttle control actuator
connector.
4. Remove two hoses on electronic throttle control
actuator.
5. Remove four electronic throttle control actuator
mounting bolts.
(Tighten: Electronic throttle control actuator bolts to
10 N·m)
6. Remove the throttle control actuator carefully.
7. Installation is in the reverse order of removal.
Engine Control Module (ECM)
Description
The Engine Control Module (ECM) for this model is serviced only as a complete unit.
Operation
The ECM is a pre-programmed, microprocessor-based digital computer. It regulates ignition timing, air-fuel ratio,
emission control devices, charging system, certain transmission features, speed control, air conditioning compressor
clutch engagement and idle speed. The ECM can adapt its programming to meet changing operating conditions.
Removal & Installation
1. Disconnect the negative battery cable.
2. Remove the glove box (See Instrument Panel Removal & Installation in Section 15 Body).
3. Disconnect the ECM electrical connector.
4. Remove the ECM retaining bolts (1).
(Tighten: ECM retaining bolts to 10 N·m)
5. Remove the ECM.
6. Installation is in the reverse order of removal.
Installation Notes:
•
NOTE :
The Immobilizer control module must be matched to
the new ECM before the vehicle will start.
Matching Immobilizer Control Module to New
Engine Control Module (ECM)
Perform the following to match the Immobilizer control
module to the new ECM:
− With the X-431 scan tool, choose T11 series.
− Choose
⬙immobilize⬙.
− Choose
⬙input code⬙.
− Input the safety code.
− Click the small keyboard.
− Click
⬙OK⬙.
− Choose
⬙Immobilizer adapt⬙.
− Choose
⬙read Immobilizer to ECM⬙ immedi-
ately.
− Click
⬙OK⬙.
