1. Remove the heater block (see chapter 5).
2. Disconnect the negative battery cable.
3. Disconnect the wiring from the stepper motor (see illustration).
4. Remove two screws, then remove the stepper motor. Remove and discard O-ring (see illustrations).
Installation
5. Installation is carried out in the reverse order of removal, pay attention to the following:
- a) Install a new O-ring, lightly lubricating it to ease installation.
- b) To prevent damage to the throttle body or stepper motor (the tip of the motor plunger protrudes more than 28 mi from the contact surface of the motor), gently push the plunger in until it stops. After starting the motor, the stepper motor will need to be reset by the ECU.
- c) Apply a few drops of Blocking Compound to the threads, then carefully tighten the screws to the specified torque specifications.
