Review INFINITI Throttle Body Assembly Oem fits FX35 2009

The **Infiniti FX35 (OBD-II Code: 16119JK20, Model Year: 2009) Throttle Body** is a precision-engineered component designed to regulate airflow into the engine s intake system, ensuring optimal performance, efficiency, and responsiveness. Manufactured to Infiniti s stringent quality standards, this throttle body is specifically tailored for the **3.7L V6 engine** found in the 2009 FX35, a luxury crossover known for its refined handling and dynamic driving experience. Crafted from high-grade materials, including durable plastic and reinforced metal components, the throttle body features a **drive-by-wire (DBW) system**, eliminating the traditional mechanical throttle linkage in favor of an electronically controlled actuator. This advanced design allows for precise throttle response, seamless acceleration, and enhanced fuel economy, all while integrating seamlessly with the vehicle s **ECU (Engine Control Unit)** via a dedicated wiring harness. The throttle body incorporates a **pulse-width modulated (PWM) motor** that adjusts throttle position based on driver input, engine load, and real-time vehicle data, ensuring smooth operation under varying driving conditions from city stop-and-go traffic to highway cruising. Its **electronic throttle control (ETC) system** also contributes to improved safety features, such as traction control and stability management, by dynamically modulating throttle response in conjunction with other engine and transmission controls. For maintenance and longevity, the throttle body is equipped with a **self-cleaning mechanism** that reduces carbon buildup on the throttle plates, a common issue in modern drive-by-wire systems, thereby maintaining consistent performance over time. Whether replacing a worn-out unit or upgrading for enhanced tuning potential, this throttle body is a critical component that plays a pivotal role in the FX35 s signature blend of power, refinement, and technological sophistication.

**Pros and Cons of Buying a 2009 Infiniti FX35 (VIN: 16119JK20) with a Throttle Body Issue**

### **Pros**

1. **Reliability of the Base Platform** The Infiniti FX35 is built on the Nissan NV350 platform, which is known for being sturdy and capable of handling heavy loads when properly maintained. Many examples of this generation have lasted well beyond 200,000 miles with regular upkeep.

2. **Strong Engine and Transmission** The 3.5L V6 (VQ35DE) is a robust engine when maintained, producing around 271 horsepower and 262 lb-ft of torque. Paired with the smooth CVT (in later models) or the reliable 6-speed automatic (in this year), it provides decent performance for its class.

3. **Spacious and Comfortable Interior** The FX35 offers a large, well-appointed cabin with good seating, ample legroom, and a premium feel compared to many competitors. The rear seats are comfortable for passengers, and the cargo space is generous.

4. **SUV-Like Capability** Unlike many luxury sedans, the FX35 has a higher ride height, making it more practical for light off-roading or snow conditions. It also handles better than a traditional sedan in rough roads.

5. **Potential for Modifications** The VQ35DE engine is a popular choice among tuners, allowing for aftermarket upgrades like cold air intakes, exhaust systems, and even forced induction (though stock reliability must be considered).

6. **Used Market Value** As a 2009 model, the FX35 is no longer brand-new, but it still holds decent resale value compared to some luxury competitors. A well-maintained example can be a good value for the features it offers.

7. **Available Luxury Features** Depending on the trim, this model may include features like leather upholstery, power-adjustable seats, heated/ventilated seats, a premium sound system, and advanced safety tech (like stability control and traction control).

### **Cons**

1. **Throttle Body Issue (Primary Concern)** The throttle body in this engine is known to develop carbon buildup over time, leading to rough idling, stalling, or poor acceleration. While this can often be fixed with a throttle body cleaning or replacement, it is a recurring issue in VQ35DE engines. If the seller hasn t addressed it, this could be a costly repair down the line.

2. **CVT Transmission (If Equipped)** Some 2009 FX35 models (especially later in the year) were fitted with a CVT, which can be less reliable than a traditional automatic transmission. CVTs are prone to overheating, slipping, and requiring frequent fluid changes. If this car has a CVT, verify its maintenance history thoroughly.

3. **Oil Consumption** The VQ35DE engine is notorious for burning oil, especially in higher-mileage examples. Regular oil changes and top-ups are necessary, and this can become an ongoing expense.

4. **Rust Concerns** Depending on where the car was driven, rust can be an issue, particularly in the wheel wells, rocker panels, and undercarriage. A thorough inspection of these areas is essential.

5. **Maintenance Costs** While not excessively expensive, Infiniti parts and labor can be pricier than some Japanese brands. The FX35 also requires more frequent maintenance than a typical sedan (e.g., suspension tune-ups, fluid changes).

6. **Resale Depreciation** Luxury vehicles, even reliable ones, depreciate quickly. If you plan to sell this car in the future, the return on investment may not be as high as with a more practical or fuel-efficient vehicle.

7. **Potential Electrical Gremlins** Like many luxury cars, the FX35 can have occasional electrical issues, such as faulty sensors, infotainment glitches, or window regulator problems. These are usually fixable but can be annoying.

8. **Fuel Economy Limitations** The V6 engine is not the most efficient, averaging around 18-22 MPG combined. If fuel costs are a concern, this may not be the most economical choice.

---

### **Conclusion**

The 2009 Infiniti FX35 is a capable, spacious luxury SUV with a strong engine and a comfortable ride. However, its value depends heavily on its maintenance history, particularly regarding the throttle body issue, oil consumption, and transmission reliability. If the throttle body has been properly serviced and the car has been well-maintained, it can be a solid used purchase. On the other hand, if these issues have been neglected, they could lead to significant repair costs.

### **Recommendation**

Before purchasing this vehicle, take the following steps:

1. **Verify the Throttle Body Condition** Ask the seller for proof that the throttle body has been cleaned or replaced. If not, budget for this repair (typically $200 $500 for parts and labor).

2. **Check Oil Consumption** Ensure the car has had regular oil changes and confirm that it hasn t been burning oil excessively. A pre-purchase inspection by a trusted mechanic is highly recommended.

3. **Inspect the Transmission** If the car has a CVT, confirm that the fluid has been changed recently (CVT fluid should be replaced every 30,000 60,000 miles). For a traditional automatic, check for smooth shifting and no slipping.

4. **Review Maintenance Records** Request full service records, especially for the engine, transmission, suspension, and electrical systems. Gaps in maintenance could indicate hidden problems.

5. **Test Drive Thoroughly** Pay attention to idling, acceleration, and any unusual noises. A rough idle or hesitation could signal throttle body or fuel system issues.

6. **Negotiate Based on Findings** If the throttle body or other issues are confirmed, use them to negotiate a lower price or request repairs before purchase.

7. **Consider Alternatives** If the throttle body issue is unresolved and the car has high mileage, you may find better value in a newer model with a more reliable powertrain or a different luxury SUV with fewer known issues (e.g., a Lexus RX or Acura MDX).

**Final Verdict:** This FX35 can be a good buy if the throttle body and other major systems are in good condition and well-maintained. However, if these issues are ignored, it could become an expensive project car. Always prioritize a thorough inspection and transparent maintenance history before committing to the purchase.
