Ensure the engine is cool and the vehicle is parked on a level surface.

2. Disconnect Battery

Sub-steps:
- Locate the battery in the engine compartment.
- Use a wrench to disconnect the negative terminal to avoid electrical shorts.

3. Remove Engine Cover (if applicable)

Sub-steps:
- Unscrew any fasteners holding the engine cover in place.
- Lift off the cover and set it aside carefully.

4. Remove the Throttle Body

Sub-steps:
- Disconnect the electrical connector from the throttle body by pressing the tab and pulling it off.
