Steps
Disconnect intake and electrical parts
Let the engine cool and switch off the ignition. Loosen the intake clamp, disconnect the MAP sensor and throttle-body plug, and move the intake hose and coolant hose bracket clear.
Remove the throttle body
Remove the throttle-body and support-bracket fasteners. Lift the unit from the intake manifold and keep debris out of the opening.
Install the replacement unit
Use a new gasket if the old one is damaged or the service procedure requires replacement. Align the throttle body with its locating features, start fasteners by hand, and tighten evenly to specification.
Reconnect and inspect
Refit the support bracket, intake hose, sensor, coolant hose retainer, and electrical connector. Check that hoses are secure and wiring is clear, then start the engine and watch for leaks or warning lights.
Check your vehicle’s repair manual for exact specifications and fit.
