Package Contents

• 1 electronic throttle body assembly

Throttle-position electronics and actuator integration should be verified from the product images and connector configuration. Gasket, seal, mounting bolts, intake duct, hoses, wiring, and installation tools are not confirmed as included.

Installation Notes

Disconnect the battery only as directed by the vehicle service procedure. Compare the replacement with the original throttle body before installation, including bore, flange, bolt spacing, connector keying and pin count, coolant or vacuum ports, and throttle-plate orientation. Inspect the intake duct, connector, wiring, grounds, vacuum hoses, and sealing surfaces. Do not force or manually move an electronically controlled throttle plate unless the service procedure specifically permits it.

Use a new gasket if required and follow vehicle-specific torque specifications. After installation, check for intake or coolant leaks and perform any required throttle/idle relearn or scan-tool setup according to the exact vehicle procedure. Clear diagnostic faults only after correcting their cause, then verify stable idle and proper throttle response in a safe area before road use.

Frequently Asked Questions

Which engine fits the Pontiac Grand Prix or Hummer H3?
The source does not specify an engine for those entries. Verify the VIN, engine code, original reference number, connector, and bore before ordering.

Is a gasket included?
Gasket inclusion is not confirmed.

Will the throttle body require relearning?
The source does not specify this. Follow the vehicle-specific service procedure; some applications may require an idle/throttle relearn or scan-tool setup.

Is this compatible with any vehicle sharing one reference number?
Not necessarily. Match the VIN, engine, full reference number, bore, bolt pattern, ports, and connector configuration.
