5 Top 2018 WRX Camshaft Position Sensors: Keep Your Boxer Roaring!
Your 2018 Subaru WRX is a masterpiece of engineering, known for its exhilarating performance and distinctive boxer rumble. But even the best engines rely on precise data, and that’s where the camshaft position sensor (CPS) comes in. This vital component ensures your engine’s timing is spot-on, leading to smooth operation, optimal fuel efficiency, and the power you crave. If you’ve been noticing a rough idle, stalling issues, or that dreaded check engine light, a faulty 2018 WRX camshaft position sensor might be the culprit.
Replacing this sensor can often resolve these pesky issues, getting your WRX back to its peak performance. But with so many options out there, how do you pick the right one? We’ve scoured the market to bring you a list of the top 5 camshaft position sensors compatible with your 2018 WRX, helping you make an informed decision and get your ride running like new again. Let’s dive in!
What Does a Camshaft Position Sensor Do?
Think of your camshaft position sensor as the eyes and ears of your engine’s computer (ECU). It monitors the rotational speed and position of the camshaft, which controls the opening and closing of your engine’s valves. This data is crucial for the ECU to precisely control fuel injection and ignition timing. Without accurate information from the sensor, your engine can’t operate efficiently, leading to a range of performance issues. For your FA20DIT engine in the 2018 WRX, having a reliable CPS is non-negotiable for optimal power delivery and fuel economy.

Q2: Can I drive my 2018 WRX with a bad camshaft position sensor?
A: While your WRX might still run with a failing CPS, it’s not advisable to drive it for long. A faulty sensor can lead to incorrect engine timing, potentially causing engine misfires, reduced performance, poor fuel economy, and in severe cases, damage to other engine components. It’s best to replace it as soon as possible.
Q3: Is it difficult to replace a camshaft position sensor on a 2018 WRX?
A: For many DIY enthusiasts, replacing a camshaft position sensor on a 2018 WRX is a moderately easy task. The sensor is usually located on or near the cylinder head. You’ll typically need basic hand tools. However, if you’re uncomfortable working on your engine, it’s always best to consult a professional mechanic.
Q4: How long do camshaft position sensors typically last?
A: Camshaft position sensors are designed to last a long time, often for the lifespan of the vehicle (100,000 miles or more). However, like any electronic component exposed to engine heat and vibrations, they can fail prematurely due to wear, electrical issues, or contamination.
Q5: Are aftermarket camshaft position sensors reliable compared to OEM parts?
A: High-quality aftermarket camshaft position sensors, like the ones reviewed here, can be just as reliable as OEM parts. Reputable aftermarket brands often engineer their sensors to meet or exceed original equipment specifications, offering a more affordable alternative without compromising performance or longevity.

A: The most common diagnostic trouble codes related to a faulty camshaft position sensor are P0340 (Camshaft Position Sensor Circuit Malfunction) and P0345 (Camshaft Position Sensor “A” Circuit Malfunction – Bank 2). Other codes might include P0341, P0346, etc., depending on the specific issue and engine configuration.
Q7: Will replacing the camshaft position sensor reset my check engine light?
A: After replacing a faulty camshaft position sensor, the check engine light (CEL) might turn off on its own after a few drive cycles. However, it’s often necessary to manually clear the diagnostic trouble codes (DTCs) using an OBD-II scanner. If the problem is resolved, the light should stay off.
