For 1990-2009 cars

### Removal Procedure

Notice: Handle the electronic throttle control components carefully. Use cleanliness in order to prevent damage. Do not drop the electronic throttle control components. Do not roughly handle the electronic throttle control components. Do not immerse the electronic throttle control components in cleaning solvents of any type.

1. An 8 digit part identification number is stamped on the throttle body casting. Refer to this number if servicing, or part replacement is required.
2. Remove the air induction assembly.

Important: Cover or plug any openings when servicing the throttle body in order to prevent possible contamination.

3. Disconnect the throttle actuator motor harness connector.
4. Disconnect the throttle position (TP) sensor harness connector.
5. Remove the throttle body attaching nuts.

Important: Do not reuse the throttle body gasket. Install a new gasket during assembly.

6. Remove the throttle body and the gasket.
7. Discard the throttle body gasket.

### Installation Procedure

1. Install a new throttle body gasket.
2. Install the throttle body assembly.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Always use a torque wrench in order to obtain the proper torque.

3. Install the throttle body attaching nuts.

Tighten
Tighten the throttle body nuts to 10 N·m (89 lb in).

Important: Ensure that the electrical connector to throttle body motor and the connector seal are properly installed and not damaged.

4. Connect the TP sensor harness connector.
5. Connect the throttle actuator motor harness connector.
6. Install the air induction assembly.
7. With the vehicle not in reduced engine power, turn ON the ignition with the engine OFF. Inspect for complete throttle opening and closing positions. Use a scan tool to monitor the throttle angles while operating the accelerator pedal to open and close the throttle. The accelerator pedal should operate freely without binding between full closed throttle and wide open throttle.
8. Start the engine.
