Steps
Disconnect the battery
Switch the ignition off and disconnect the negative battery terminal. Keep the cable clear of the post while working on throttle wiring.
Remove the air-intake assembly
Release the air-box clips and intake clamps, unplug the intake sensor, and disconnect the PCV hose. Remove the air-box fasteners and lift the intake assembly out of the way.
Remove the throttle body
Release the electrical connector lock and unplug the throttle body. Remove its mounting bolts, lift the assembly away, and clean the gasket surface without dropping debris into the intake.
Fit the replacement throttle body
Inspect and clean the manifold face, seat a correct gasket, and align the replacement assembly. Start the bolts by hand, tighten them evenly to engine-specific specification, and reconnect the plug.
Reinstall the intake
Return the air box and intake tube to their mounts, reconnect the sensor and PCV hose, and tighten clamps without pinching hoses. Confirm the air path is sealed.
Reconnect and verify operation
Reconnect the battery and follow the maker's throttle initialization procedure if required. Start the engine, confirm stable idle and no warning lights, and check for intake leaks.
Check your vehicle’s repair manual for exact specifications and fit.
