Review MITSUBISHI Gas Accelerator Pedal Oem fits ECLIPSE 2009

The **Mitsubishi 546.MS1V09 (09 Eclipse) Gas Accelerator Pedal (Part #3914-4)** is a precision-engineered component designed specifically for the 2009 Mitsubishi Eclipse, ensuring seamless integration with the vehicle s throttle control system. This high-quality accelerator pedal is crafted from durable, corrosion-resistant materials, including reinforced plastic and metal components, to withstand the demands of daily driving while maintaining long-term reliability. The pedal features a smooth, responsive action, allowing for precise throttle modulation whether the driver is cruising on the highway or navigating tight city streets. Its ergonomic design minimizes fatigue during extended periods of use, while the secure mounting ensures stability and prevents unwanted movement or rattling. This part is a direct-fit replacement for the original equipment (OEM) pedal, maintaining the same performance characteristics and compatibility with the Eclipse s electronic throttle control (ETC) system. Whether replacing a worn-out pedal or upgrading for improved feel, this accelerator pedal delivers a balance of durability, responsiveness, and ease of installation, making it an ideal choice for both DIY enthusiasts and professional mechanics.

### **Pros and Cons of Buying a Mitsubishi 546.MS1V09 (2009 Eclipse Gas Accelerator Pedal Part #3914-4)**

#### **Pros:**

1. **Direct Fitment and Compatibility** The accelerator pedal (part #3914-4) is designed specifically for the 2009 Mitsubishi Eclipse with the MS1V09 engine. This ensures proper alignment, functionality, and compatibility with the vehicle s throttle linkage system, reducing the risk of installation issues.

2. **OEM Quality** As an original equipment manufacturer (OEM) or high-quality aftermarket replacement, this pedal is built to Mitsubishi s specifications. This means it should match the durability and performance of the original component, reducing premature wear or failure.

3. **Easy Installation** The pedal is a straightforward replacement part, typically requiring only basic tools. Many users report that it can be installed in under an hour, especially if the original pedal was the source of the issue (e.g., sticking, loose connection, or electrical failure).

4. **Cost-Effective Repair** Replacing just the accelerator pedal is far cheaper than overhauling the entire throttle body or electronic control system. This makes it a practical solution for issues like a slow or unresponsive throttle response.

5. **Prevents Further Damage** A faulty accelerator pedal can cause erratic engine behavior, stalling, or even damage to the throttle position sensor (TPS) or engine control unit (ECU) over time. Replacing it early can prevent more expensive repairs down the line.

6. **Widely Available** This part is commonly stocked by auto parts retailers (both online and in-store), making it easy to source without long wait times.

#### **Cons:**

1. **Potential for Counterfeit Parts** If purchasing from an untrusted seller (especially online marketplaces), there is a risk of receiving a knockoff or low-quality replica. Always verify the seller s reputation and check for authenticity markings.

2. **Electrical or Wiring Issues** While the pedal itself may be functional, the problem could stem from wiring harness damage, a faulty throttle position sensor, or a malfunctioning ECU. Replacing just the pedal without diagnosing these components may not fully resolve the issue.

3. **Throttle Body Contamination** If the throttle body is dirty or clogged with carbon deposits, a new pedal may not perform optimally. Cleaning or replacing the throttle body may be necessary for best results.

4. **Pedal Position Sensor (PPS) Dependency** The MS1V09 engine uses a pedal position sensor (PPS) to relay throttle position data to the ECU. If the PPS is failing alongside the pedal, replacing just the pedal may not fix the problem. A diagnostic scan is recommended before purchase.

5. **Mixed Reviews on Durability** Some owners report that aftermarket accelerator pedals wear out faster than OEM parts, especially in high-mileage vehicles. If the pedal fails again soon after installation, further investigation (e.g., throttle linkage, TPS) may be needed.

6. **Limited Longevity in Aggressive Driving** Heavy or aggressive driving (e.g., rapid throttle inputs, drifting) can accelerate wear on the pedal and its associated components. Expect normal wear over time, even with a quality replacement.

### **Conclusion:**

The **Mitsubishi 546.MS1V09 (2009 Eclipse) accelerator pedal (part #3914-4)** is a practical and cost-effective solution for addressing issues like a sticky, loose, or unresponsive throttle pedal. It offers **direct fitment, OEM-quality replacement, and ease of installation**, making it a viable choice for DIY mechanics or those seeking a quick fix. However, it is not a universal cure **underlying electrical, sensor, or throttle body problems must be addressed separately** to ensure long-term reliability.

Before purchasing, **verify the part s authenticity, check for related symptoms (e.g., check engine lights, erratic idle), and consider cleaning or replacing the throttle body and pedal position sensor** if needed. If the issue persists after replacement, further diagnostics (e.g., ECU or wiring inspection) may be required.

---

### **Recommendation:**

- **Buy from a reputable seller** (e.g., RockAuto, Amazon with verified reviews, or a local Mitsubishi specialist) to avoid counterfeit parts.

- **Perform a diagnostic scan** (using an OBD-II scanner) to check for throttle-related trouble codes before buying.

- **Inspect the throttle body and pedal position sensor** clean or replace them if dirty or faulty.

- **Follow installation instructions carefully**, ensuring proper wiring and mechanical connections.

- **Monitor the pedal s performance post-installation** if issues recur, consult a mechanic to rule out deeper electrical or sensor problems.

For most cases where the pedal itself is the culprit, this part will provide a **reliable and affordable fix**. However, treat it as part of a broader throttle system evaluation rather than a standalone solution.
