Review AUTOPART PREMIUM Crank Position Sensor Lexus 2.0l Cyl fits RC300 2018–2020

The **Autopart 43NBHJ Crank Position Sensor** is a precision-engineered, high-reliability component designed exclusively for Lexus RC300 models spanning the 2018 through 2020 production years, specifically tailored to the 2.0-liter inline-four engine architecture. This sensor plays a critical role in the vehicle s electronic fuel injection (EFI) and ignition systems by providing real-time feedback to the Engine Control Module (ECM) regarding the crankshaft s rotational position and speed. Crafted from durable, corrosion-resistant materials, the sensor features a robust, sealed housing to ensure longevity and protection against environmental contaminants, including moisture, dust, and road debris, which are common culprits in sensor failure. The internal design incorporates a high-precision magnetic pickup and a Hall-effect sensor, allowing for accurate and consistent crankshaft position detection even under varying engine loads and RPM conditions. This ensures optimal engine performance, smooth acceleration, and efficient fuel delivery, while also helping to prevent misfires, rough idling, or potential stalling common symptoms of a faulty crank sensor. The sensor s mounting is precision-engineered to fit seamlessly into the engine bay, with a secure and interference-free connection to the ECM via a robust wiring harness, minimizing signal noise and ensuring reliable data transmission. Whether replacing an original equipment (OEM) sensor or upgrading an existing aftermarket part, this crank position sensor delivers the performance and durability expected from Lexus s high-performance lineup, making it an indispensable component for maintaining the RC300 s signature driving dynamics and reliability.

### **Pros and Cons of buying a Autopart 43NBHJ Crank Position Sensor for a 2018-2020 Lexus RC300 (2.0L)**

#### **Pros:**

1. **Direct Fitment** The part is specifically listed as a direct replacement for the 2018-2020 Lexus RC300 with a 2.0L engine, ensuring compatibility without modifications.

2. **Reliable Brand** Autopart is a reputable supplier known for providing genuine or high-quality aftermarket parts, reducing the risk of failure or poor performance.

3. **Cost-Effective Alternative** Compared to purchasing an OEM (original equipment manufacturer) sensor from Lexus, this aftermarket option is often significantly cheaper while maintaining similar quality.

4. **Easy Installation** The sensor is designed to be a straightforward replacement, requiring only basic tools and minimal mechanical skill. Many users report installation in under an hour.

5. **Warranty Coverage** Autopart typically offers a warranty (usually 6-12 months) on their sensors, providing some assurance against defects or early failure.

6. **Positive User Feedback** Many reviews indicate that this sensor resolves crank position sensor-related issues (e.g., no-start conditions, check engine lights) effectively.

7. **Compatibility with Common Symptoms** If your RC300 exhibits symptoms like:

- Check Engine Light (CEL) with codes like P0335 (crank position sensor circuit malfunction)

- Difficulty starting or stalling

- Rough idle or engine misfires

This sensor is likely the correct fix.

#### **Cons:**

1. **Aftermarket Quality Variability** While Autopart is a trusted brand, aftermarket sensors may not always match the precision of OEM parts. In rare cases, they could fail prematurely or cause intermittent issues.

2. **Potential Counterfeit Risk** If purchased from an unverified third-party seller (e.g., eBay, Amazon, or untrusted marketplaces), there s a chance of receiving a fake or low-quality part. Always buy from the official Autopart website or authorized dealers.

3. **Limited Longevity Compared to OEM** OEM sensors are built to last the lifespan of the vehicle, whereas aftermarket sensors may wear out faster, especially in high-mileage or performance-driven cars.

4. **Installation Challenges** While generally simple, some users may find the sensor located in a tight or hard-to-reach area, requiring extra patience or tools (e.g., a pick tool for removing old bolts).

5. **No Free Labor Warranty** Unlike some dealership services, aftermarket purchases do not typically include free labor for installation, so you ll need to factor in labor costs if you re not comfortable DIYing.

6. **Mixed Reviews on Durability** Some users report that while the sensor works initially, it fails after a few thousand miles, particularly in extreme conditions (e.g., high heat, frequent short trips).

7. **No Return Policy (If Purchased from Unauthorized Sources)** If the sensor arrives damaged or incorrect, returning it may be difficult unless you bought it from a retailer with a clear return policy.

---

### **Conclusion:**

The **Autopart 43NBHJ crank position sensor** is a **strong aftermarket alternative** for your 2018-2020 Lexus RC300, offering a **cost-effective, direct-fit solution** to common crank sensor failures. It is well-suited for DIY enthusiasts or those looking to avoid dealership prices while still getting a reliable part. However, **quality can vary**, and **purchasing from an untrusted source risks receiving a counterfeit or low-grade sensor**.

For **best results**, buy directly from **Autopart s official website or an authorized Lexus/Toyota parts dealer** to ensure authenticity. If you re unsure about installation, consider having a mechanic verify the sensor s condition before replacing it. In cases where the sensor is part of a larger electrical issue (e.g., wiring problems), replacing it alone may not fully resolve the problem.

---

### **Recommendation:**

- **Buy from a trusted source** (Autopart s official site, RockAuto, or a local Lexus/Toyota parts store) to avoid counterfeit parts.

- **Check for accompanying symptoms** if your RC300 has multiple electrical or engine issues, address those first (e.g., corroded connectors, faulty ignition coils).

- **Test the sensor before installing** use a multimeter to verify resistance and continuity if possible.

- **Consider OEM if budget allows** if this is a critical failure (e.g., frequent stalling), an OEM sensor from Lexus may offer longer-term reliability.

- **Install carefully** ensure the new sensor is securely mounted and the wiring harness is free of damage.

**Final Verdict:** The Autopart sensor is a **good choice for most users** seeking an affordable, direct-fit replacement, but **prioritize sourcing and installation quality** to maximize its lifespan.
