Review SUBARU Camshaft Position Sensor Oem fits WRX STI 2015–2019

The **Subaru J5T32871 Camshaft Position Sensor (CMP Sensor) for 2015 2019 WRX STI models** is a critical component of the engine s ignition and performance management system, designed to provide real-time feedback on the rotational position and speed of the camshaft. This precision-engineered sensor, part of Subaru s FA20 engine family, plays a pivotal role in optimizing fuel injection timing, ignition spark delivery, and overall engine efficiency ensuring seamless power delivery, improved throttle response, and enhanced fuel economy. Manufactured to exacting specifications, the J5T32871 sensor features a robust magnetic design with a high-precision Hall-effect switch, allowing it to detect even the slightest fluctuations in camshaft movement with unparalleled accuracy. Its compact yet durable construction is built to withstand the demanding conditions of high-performance driving, including the aggressive power outputs and turbocharged boost pressures characteristic of the WRX STI s FA20 engine. Compatible exclusively with the 2015 through 2019 model years, this sensor is a direct-fit replacement for the original equipment (OEM) part, ensuring seamless integration with the engine control unit (ECU) and supporting systems. Whether replacing a worn-out or faulty sensor due to age, mechanical stress, or electrical failure, this aftermarket component is engineered to restore optimal engine performance, eliminate misfires, and prevent check engine light (CEL) codes such as P0340, P0341, or P0342. Built with high-quality materials and subjected to rigorous testing, the J5T32871 camshaft position sensor is a dependable choice for enthusiasts and mechanics seeking a reliable upgrade or replacement that maintains the integrity of Subaru s legendary turbocharged performance.

### **Pros and Cons of Buying a 2015-2019 Subaru WRX STI Camshaft Position Sensor (Part # J5T32871)**

1. **Direct OEM Replacement** This is a genuine Subaru part, ensuring compatibility with the 2015-2019 WRX STI engine (FA20F). It meets the same quality and performance standards as the original equipment manufacturer (OEM) component.

2. **Reliability** Subaru s OEM sensors are designed to last the life of the vehicle under normal conditions. A faulty camshaft position sensor can cause misfires, rough idling, or even engine stalling, so replacing it with a reliable part prevents long-term issues.

3. **Warranty Coverage** If purchased from an authorized Subaru dealer or a reputable aftermarket supplier, this part may come with a warranty, providing peace of mind against premature failure.

4. **Easy Installation** The sensor is relatively straightforward to replace, requiring only basic tools (socket wrench, torque wrench, and possibly a scan tool to reset the engine codes). No major modifications or specialized equipment are needed.

5. **Prevents Engine Damage** A failing camshaft position sensor can lead to catastrophic engine failure if left unchecked. Replacing it early avoids costly repairs.

6. **Cost-Effective** While not the cheapest option, it is more affordable than engine rebuilds or replacements, making it a practical solution for maintaining the vehicle s performance.

1. **Higher Upfront Cost** Compared to aftermarket or generic sensors, the OEM part is more expensive. Prices typically range between **$150 $250**, depending on the retailer.

2. **Potential Counterfeit Risks** If purchasing from an untrusted seller (e.g., eBay, Craigslist, or uncertified online marketplaces), there is a risk of receiving a counterfeit or low-quality part. Always buy from authorized dealers or verified suppliers.

3. **Limited Availability** OEM parts may not always be in stock at local Subaru dealerships, requiring online ordering or waiting for delivery.

4. **Miscellaneous Costs** Beyond the sensor itself, you may need to budget for labor (if not DIY), a scan tool (if codes are unclear), and possibly a new O-ring or gasket if the sensor housing is damaged.

5. **No Performance Upgrade** Unlike some aftermarket sensors (which may offer slight tuning benefits), this is a direct replacement and does not enhance engine performance only restores proper function.
