Steps
Remove the intake duct
Open the hood and remove the engine cover. Loosen the intake clamps, disconnect the valve-cover hose, and move the intake snorkel away from the throttle body.
Remove the throttle body
Unplug the throttle-body connector and remove the mounting fasteners. Lift the unit forward and check the gasket surface for damage or residue.
Install the replacement throttle body
Position the replacement with the correct gasket, align its holes, and start the fasteners by hand. Tighten them evenly to the vehicle's specification, then reconnect the electrical plug.
Restore the intake components
Reconnect the intake snorkel and valve-cover hose, secure the clamps, and reinstall the engine cover. Verify the duct is fully seated and no connectors were left unplugged.
Perform the idle relearn
Start the engine and allow it to idle using the vehicle maker's throttle-body relearn procedure. Confirm stable idle and throttle response, then scan for codes if the warning light remains on.
Check your vehicle’s repair manual for exact specifications and fit.
