On a 2010 Ford Fusion, the throttle body is mounted to the intake manifold on the engine side, typically near the passenger side of the engine bay and connected to the air intake tube from the air filter box. It uses electronic throttle control rather than a traditional cable.
Engine options and throttle body placement
The Fusion offered more than one engine in 2010, but the throttle body generally sits in the same region relative to the intake plenum. The exact position can vary slightly depending on the engine, but you’ll usually find it where the large air intake hose meets the engine.
- 2.5L Duratec I-4: Throttle body attached to the top of the intake plenum on the passenger side, with the air intake hose from the air filter box feeding into it. It operates via electronic throttle control (drive-by-wire).
- 3.0L Duratec V6: Throttle body mounted to the intake manifold on the passenger side/front area, connected to the air intake boot and also using electronic throttle control.
Regardless of engine, you’ll not find a throttle cable; the 2010 Fusion uses an electronic throttle body that communicates with the engine computer.
How to visually identify the throttle body
Visual cues
Look for a cylindrical or rectangular metal/black component with an electrical connector and a large rubber hose or duct attached to its side. It sits where the air intake tube meets the engine, typically toward the front-right (passenger) side of the engine bay.
Maintenance considerations
Things to know before servicing
Always disconnect the negative battery terminal before working near the throttle body area to protect the engine electronics. If cleaning the throttle body, use approved throttle-body cleaner and avoid scrubbing the throttle plate vigorously. Be mindful of nearby sensors, such as the MAF sensor and idle air control valve, which can be affected by improper cleaning.
Summary
The throttle body on a 2010 Ford Fusion is located on the engine’s intake manifold, usually on the passenger side, and is fed by the air intake hose from the air filter housing. It is an electronically controlled unit, and its exact mounting slightly varies between the 2.5L I-4 and 3.0L V6 engines. When servicing, always take standard safety steps and consult the vehicle’s service manual for engine-specific details.
