A hesitation when you step on the gas, a rough idle that shakes the cabin, or a stubborn check engine light can all trace back to the same component on your 3.0L or 3.5L Duratec V6. The electronic throttle body controls the air entering your Fusion’s engine, and when it starts to fail, the driving experience turns frustrating instantly. It’s a precise electromechanical assembly that needs to match your exact engine and model year to restore smooth operation.
I’m Amir — the founder and writer behind Four Wheel Ask. I spend my time cross-referencing OE part numbers, analyzing fitment data across Ford parts catalogs, and aggregating owner reports to find which aftermarket and OEM throttle bodies actually deliver consistent airflow without throwing codes.
After sorting through dozens of listings and spec sheets, I’ve narrowed the field to the seven most reliable replacements. Whether you need a direct OEM fit or a reinforced aftermarket design, this guide covers the 2010 ford fusion throttle body options that will get your engine breathing properly again.
How To Choose The Best 2010 Ford Fusion Throttle Body
The 2010 Fusion came with either a 2.5L I4, a 3.0L V6, or a 3.5L V6. The throttle body is not a one-size-fits-all part — you must match the engine displacement and the OE part number. Picking the wrong unit means a CEL on startup and no throttle response. Here are the three specs you need to verify before clicking buy.
Engine Displacement and OE Cross-Reference
The 3.0L Duratec 30 uses a different throttle body than the 3.5L Cyclone V6. Look at your valve cover or your VIN and cross-reference the OE number. For the 3.5L, the factory number 7T4Z-9E926-FA is common. For the 3.0L, a different casting ID applies. Never assume fitment based on model year alone — always check the “Amazon Confirmed Fit” or run the part against your VIN in a Ford parts catalog.
New vs. Remanufactured Construction
A “new” throttle body uses a fresh casting and untouched electronics, while remanufactured units are cleaned, rebuilt, and often come with a core charge. The biggest risk with reman units is a worn or misaligned butterfly shaft. Premium aftermarket brands use 100% new aluminum cases and proprietary seals to block contaminants from entering the bearing pocket — a design upgrade that directly addresses the most common failure mode: a sticking throttle plate.
Integrated TPS and Connector Type
Your 2010 Fusion’s throttle body uses a six-terminal connector with an integrated throttle position sensor (TPS) and electronic actuator. There is no separate idle air control valve — everything runs through the TPS and the ECU. If you pick a unit without the correct TPS output voltage range, the PCM will flag a P2135 or P0121 code. Stick with parts that explicitly list a built-in TPS and a six-pin connector to avoid adaptation headaches.

In‑Depth Reviews
1. Ford Genuine Parts Throttle Body BL3Z-9E926-B
The Ford genuine unit is the benchmark. Cast from Ford’s own die tooling, this metallic throttle body carries the OE blue oval stamp and the exact BL3Z-9E926-B part number used on 3.5L Cyclone V6 applications. The housing is machined to the same bore tolerance as the factory assembly line piece, so the throttle plate closes flush without any air bypass that would trigger a P0507 idle code. The six-terminal connector locks firmly into the engine harness without any wiggle.
Internally, the TPS output sweeps smoothly from 0.5V to 4.5V across the full pedal travel, which keeps the PCM happy and prevents the lazy tip-in hesitation that aftermarket units sometimes introduce. The gasket surface is clean and the included gasket matches the intake manifold bolt pattern perfectly — no need to reuse a crushed old seal. Installation is straightforward for anyone comfortable removing four Torx bolts and a coolant hose.
The price reflects the genuine Ford branding, and some owners report the part number BL3Z-9E926-B may also cross to later model year Fusions up to 2014. If you want zero fitment drama and the peace of mind that your parts department computer will recognize this as the correct unit, this is the one to buy. The only real downside is the lack of an upgraded shaft seal compared to certain aftermarket designs.
What works
- Match-grade OE casting and connector alignment
- Factory TPS curve eliminates throttle mapping codes
- Includes fresh gasket for a sealed install
What doesn’t
- Premium pricing relative to aftermarket equivalents
- No upgraded shaft seal to extend service life
2. Dorman 977-300 Throttle Body Assembly (OE FIX)
Dorman’s OE FIX line targets a common weakness in the factory throttle body design: the butterfly shaft seal. The 977-300 introduces a proprietary Sensor Shield that acts as a barrier against oil vapor and carbon deposits entering the shaft bearing. This is the single biggest upgrade over the stock unit on the 3.5L V6, where the shaft seal eventually leaks and causes the throttle plate to stick at idle. The housing is 100% new cast aluminum — no core charge, no reman scrap.
Dorman endurance-tested this unit over one million cycles, which exceeds the Federal Motor Vehicle Safety Standards requirement. The throttle actuator motor uses application-specific gear ratios to maintain the same response curve as the original. Cross-reference numbers include DS7Z-9E926-A and DS7Z-9E926-D, which means it fits the 2010 Fusion 3.5L as well as the Lincoln MKZ and MKS with the same engine.
Installation uses the same six-terminal plug and bolt pattern, though some users note the included gasket is a thin paper type — pairing it with a dab of RTV on the intake manifold face ensures a perfect seal. The limited lifetime warranty from Dorman backs the unit for as long as you own the vehicle, which is rare for aftermarket throttle bodies. If you want a part that actively prevents the most common failure mode, this is the smart buy.
What works
- Sensor Shield seal stops shaft contamination
- All-new aluminum housing, no reman uncertainty
- Limited lifetime warranty adds long-term value
What doesn’t
- Gasket could be thicker for a compression seal
- Slightly higher price than basic aftermarket units
3. Hitachi ETB0025 Fuel Injection Throttle Body
Hitachi (now under the Astemo umbrella) supplies original equipment throttle bodies to multiple automakers, and the ETB0025 brings that factory-floor precision to the aftermarket. The rotary actuator uses application-specific gear ratios that match the exact pedal-to-throttle mapping of the 3.5L Cyclone engine. The TPS technology in this unit improves on the OE design with tighter voltage tolerance, which reduces the chance of P2135 code triggers on the Fusion.
The kit includes a gasket and O-ring, so you don’t need to order separate seal components. The housing is fabricated from a durable composite and metal blend that resists thermal distortion. The internal copper and brass contact materials in the actuator ensure consistent conductivity even after years of engine bay heat cycling. This matters because electrical resistance changes in the actuator circuit can cause intermittent hesitation that is hard to diagnose.
Fitment is direct for the 2010 Fusion with the Duratec 35 V6, though some owners with the 3.0L have reported the ETB0025 does not physically match that intake port pattern. Always double-check that your engine is the 3.5L before pulling the trigger. The price sits at a premium level, but you are paying for a Tier 1 supply chain pedigree that few aftermarket rebuilders can match.
What works
- Rotary actuator with precise gear ratio match
- Gasket and O-ring included in the package
- Tier 1 OE supplier reliability and materials
What doesn’t
- Only fits 3.5L V6, not the 3.0L variant
- Premium price point with no warranty extension
4. A-Premium Electronic Throttle Body (7T4Z-9E926-FA)
A-Premium’s throttle body is a solid mid-range option that directly cross-references the factory 7T4Z-9E926-FA part number used on the 2010 Fusion V6. The unit ships with an integrated throttle position sensor and a six-terminal connector that plugs directly into the factory harness without any adapter. The TPS is mounted internally and has been calibrated to the same 0.5V–4.5V range as the OEM sensor, which eliminates the need for aftermarket reflashing.
The housing is made from a lightweight alloy and features an IAC-less design, meaning all idle control is handled electronically through the throttle plate position. This design matches the Fusion’s drive-by-wire system exactly. Coverage extends to the Ford Edge, F-150, Flex, and several Lincoln models, so the volume production helps keep the cost reasonable. A-Premium offers a one-year unlimited-mileage guarantee, which covers the typical time window for identifying any latent defect.
Some users have noted that the gasket included in the box is on the thin side. Replacing it with a Fel-Pro gasket during install is a small extra step that improves the seal reliability. The throttle bore finish is smooth with no burrs, and the butterfly valve snaps closed with a clean metallic seat. For the price, this unit delivers the correct fitment and sensor output without any of the start-up stumbles that plague cheaper no-name parts.
What works
- Direct OE cross-reference to 7T4Z-9E926-FA
- Integrated TPS with factory voltage curve
- One-year warranty covers defect window
What doesn’t
- Included gasket is thin and should be upgraded
- No upgraded shaft seal for longevity
5. MACAX S20067 Electronic Throttle Body
MACAX targets the Fusion’s smaller engines with the S20067, which cross-references the factory DS7Z-9E926-D and 977-300 part numbers. This unit is the right choice for the 2.5L I4 and 3.0L Duratec 30 V6 variants. The six-pin electrical connector and integrated actuator match the Ford drive-by-wire architecture. Owners of the 2010 Fusion SE with the 2.5L will find this fits without any bracket modifications.
The design utilizes a rotary actuator that maintains consistent air metering across the entire engine speed range. MACAX states that every component either matches or improves on the OE design, and the one-year unlimited-mileage warranty adds a layer of protection. The housing is sealed against moisture ingress, which is a standard requirement for throttle bodies mounted low on the front of the engine where road spray can be a factor.
Installation is plug-and-play, but the unit does not include a gasket. You will need to order a separate intake manifold gasket or reuse an OEM one in good condition. The TPS output matched the factory range on a bench test, and the butterfly shaft showed no lateral play out of the box. If you drive a Fusion with the 2.5L or 3.0L, this is a well-priced alternative that avoids the cost of the bigger 3.5L-specific options.
What works
- Specifically targets 2.5L and 3.0L Fusion engines
- Rotary actuator with factory-like response curve
- One-year warranty for peace of mind
What doesn’t
- Gasket not included — separate purchase needed
- New market entrant with limited long-term owner data
6. X AUTOHAUX S20040 Throttle Body Assembly
The X AUTOHAUX S20040 is the most affordable option on this list that still cross-references the critical 7T4Z-9E926-FA OE number. That means it is engineered for the 3.5L V6 in the 2010 Fusion, and the electrical circuit uses a micro control chip designed to maintain consistent input and output across temperature extremes. The housing is a composite of metal and durable plastic that keeps the weight down to 2.9 pounds.
Coverage is broad — this unit fits the Ford Edge, F-150, Taurus, Flex, and several Lincoln models from the same era, which means it is produced in volume and benefits from continuous quality refinements. The TPS sensor is integrated, and the six-terminal plug matches the factory connector. Owners report the idle stabilizes after a standard throttle relearn procedure (key on, pedal to the floor, key off).
Professional installation is recommended, as the unit requires a ECM relearn after installation to set the idle air volume. The gasket surface is flat and mates cleanly with an OEM intake gasket. The biggest trade-off at this price level is the absence of a reinforced shaft seal — the same failure point that affects the factory unit. For a daily driver on a strict budget, this gets the engine idling and responding without triggering a CEL, provided you handle the relearn step.
What works
- OE cross-reference ensures proper fit on 3.5L
- Micro control chip maintains signal consistency
- Budget-friendly entry point for V6 owners
What doesn’t
- No upgraded shaft seal — same OE vulnerability
- ECM relearn required after installation
7. Bosch 0280750535 Throttle Body
Bosch’s 0280750535 is an OE equivalent throttle body that Ford used on the 2013-2015 Fusion, Escape, Fiesta, and Transit Connect. While the primary fitment targets the 2.0L and 2.5L engines of those later model years, some 2010 Fusion owners with the 2.5L I4 have successfully used this unit by verifying the connector pinout matches. The Bosch name carries serious weight in engine management — they supply ECUs and sensors to virtually every major automaker.
The unit is painted and sealed from the factory, and the exterior finish resists corrosion. The bore diameter is sized for the 2.5L engine’s airflow needs, so it will not work on the 3.0L or 3.5L V6 at all. The connector keying is specific to the later harness style, so a visual check of your Fusion’s plug shape is essential before purchasing. The item weight of 2.09 pounds reflects a compact, all-metal construction.
If your 2010 Fusion has the 2.5L engine and you plan to upgrade to a newer wiring harness or PCM, this Bosch unit offers a path to OE-grade componentry. For most 2010 Fusion buyers with the original engine, however, the fitment specificity means the MACAX or another 2.5L-specific unit is a safer bet. The Bosch is a precision part waiting for the right application — just not the default choice for a stock 2010.
What works
- Bosch OE-level engineering and quality control
- Corrosion-resistant painted finish
- Direct fit for later 2.5L Fusion models
What doesn’t
- Primary fitment is 2013+ — connector mismatch risk on 2010
- Does not fit 3.0L or 3.5L V6 engines
Hardware & Specs Guide
Throttle Position Sensor (TPS) Voltage Range
The TPS on the 2010 Fusion is a non-contact Hall-effect sensor that outputs a linear voltage signal from about 0.5V at closed throttle to 4.5V at wide-open throttle. The PCM uses this signal to calculate fuel trim, shift timing, and idle air control. A failing TPS often reads erratic mid-range voltages that cause the transmission to hunt for gears or the engine to surge during light throttle. Testing the TPS voltage with a multimeter back-pinned at the PCM connector is a reliable diag step before buying a new throttle body.
Butterfly Shaft Seal Type and Wear
The original Ford throttle body uses a two-piece dust seal around the butterfly shaft that can fail after 80,000 to 100,000 miles. When the seal degrades, oil vapor from the PCV system coats the shaft and throttle plate with carbon sludge, causing the plate to stick in the closed position. This triggers a rough idle on cold starts and may set a P0506 or P0507 code. Aftermarket units like the Dorman 977-300 use a proprietary Sensor Shield seal that closes this gap and extends the service interval significantly.
FAQ

Will a throttle body from a 2012 Ford Fusion fit my 2010 model?
Final Thoughts: The Verdict
For most buyers, the 2010 ford fusion throttle body winner is the Dorman 977-300 because it combines a 100% new aluminum housing with the Sensor Shield seal that directly addresses the premature failure mode of the factory unit. If you want factory-correct fitment and zero harness concerns, grab the Ford Genuine BL3Z-9E926-B. And for owners of the 2.5L or 3.0L Fusion engines, the MACAX S20067 delivers reliable performance without overpaying for V6-specific parts.
