Removal & Installation
Drain the coolant.
- Remove the air intake duct.
Disconnect the Idle Air Control (IAC) valve electrical connector.
Disconnect the Throttle Position (TP) sensor electrical connector.
- Remove the accelerator control cable bracket.
- Disconnect the throttle body coolant bypass hoses.
- Disconnect the heater pipe nut at the throttle body.
Remove the nuts and bolts holding the throttle body to the intake manifold.
- Remove the throttle body assembly.
- Remove the old gasket.
- Clean the gasket surface on the intake manifold and the throttle body assembly.
- Install a new gasket, if necessary.
Install the throttle body assembly.
NOTEUse 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.
- Install the throttle body retaining nuts and bolts, and tighten the throttle body retaining nuts and bolts to 21 ft. lbs. (28 Nm).
- Connect the throttle body coolant bypass hoses.
- Connect the heater pipe nut at the throttle body.
- Connect the IAC valve electrical connector.
- Connect the TP sensor electrical connector.
- Install the accelerator controls cable bracket.
- Install the air intake duct.
Refill the coolant.
NOTEThe throttle should operate freely without binding between full closed and wide open throttle.
- Inspect for complete throttle opening and closing positions by operating the accelerator pedal. Also inspect for poor carpet fit under the accelerator pedal.
