7 Top Subaru Forester Camshaft Position Sensor Replacements for Smooth Performance
Dealing with a flickering “Check Engine” light or a rough-running engine in your beloved Subaru Forester? Chances are, a faulty Subaru Forester camshaft position sensor might be the culprit. This crucial component plays a vital role in your engine’s timing, ensuring everything runs smoothly. When it goes bad, you could experience anything from difficult starts to reduced fuel efficiency.
Don’t fret! Replacing this sensor is a common fix, and with the right part, you can get your Forester back to its optimal performance. But with so many options out there, how do you choose? We’ve sifted through the market to bring you a detailed review of the 7 best Subaru Forester camshaft position sensor replacements, helping you make an informed decision. Let’s dive in!
Why Your Subaru Forester Needs a Healthy Camshaft Position Sensor
Before we look at the products, let’s quickly touch on why this sensor is so important. The camshaft position sensor (often abbreviated as CMP sensor) works hand-in-hand with your crankshaft position sensor. Its job is to monitor the speed and position of the camshaft, which controls the opening and closing of your engine’s valves. This data is then sent to your car’s Engine Control Unit (ECU), allowing it to precisely adjust fuel injection and ignition timing.
When a Subaru Forester camshaft position sensor fails, the ECU doesn’t get accurate information. This can lead to various issues, including:
* Engine stalling or rough idling
* Difficulty starting, especially when warm
* Reduced engine performance or acceleration
* Increased fuel consumption
* The dreaded “Check Engine” light illuminating on your dashboard
Replacing a faulty sensor isn’t just about getting rid of a dashboard light; it’s about restoring your Forester’s reliable operation and preventing potential damage to other engine components.

How to Choose the Right Camshaft Position Sensor for Your Forester
When picking out a new Subaru Forester camshaft position sensor, here are a few quick tips to ensure you get the perfect fit:
- Know Your Year, Make, and Model: This is crucial. Even within the Subaru Forester line, sensor types can vary significantly by production year and engine size (e.g., 2.0L vs. 2.5L, naturally aspirated vs. turbocharged).
- Check the OE Part Number: If possible, remove your old sensor and note its part number. This is the most accurate way to ensure a direct replacement.
- Inspect the Connector: Pay attention to the number of pins (2-pin vs. 3-pin) and the connector’s shape or angle.
- Read Reviews: Customer impressions can give you real-world insights into the product’s quality and fitment.
- Consider the Warranty: A good warranty offers peace of mind in case of defects.
Frequently Asked Questions (FAQ)
Q1: What are the common symptoms of a failing Subaru Forester camshaft position sensor?
A1: Common symptoms include the “Check Engine” light illuminating, rough idling, engine stalling (especially after warming up), difficulty starting, reduced engine power, and increased fuel consumption. You might also notice poor acceleration or misfires.
Q2: Can I drive my Subaru Forester with a bad camshaft position sensor?
A2: While your car might still run, it’s generally not recommended. A faulty sensor can lead to incorrect engine timing, which may cause further damage to internal engine components over time. It can also leave you stranded if the engine stalls completely.
Q3: Is replacing a camshaft position sensor a difficult DIY job for a Subaru Forester?
A3: For many Subaru Forester models, replacing the camshaft position sensor is a relatively straightforward DIY task, often involving just one bolt and an electrical connector. However, the exact location can vary by engine and model year, and some might be harder to access than others. Always consult your vehicle’s service manual or watch online tutorials for your specific model.
Q4: How much does it cost to replace a camshaft position sensor on a Subaru Forester?
A4: The cost of the sensor itself typically ranges from $20 to $80 for aftermarket parts, as seen in our reviews. If you take it to a mechanic, labor costs can add another $50 to $200, depending on the mechanic’s rates and the complexity of accessing the sensor.
Q5: Will replacing the camshaft position sensor turn off my Check Engine Light?
A5: Yes, in most cases, if the camshaft position sensor was the sole cause of the “Check Engine” light, replacing it should turn off the light. Sometimes, you may need to clear the error codes with an OBD-II scanner after replacement.
Q6: What is the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both are vital for engine timing. The camshaft position sensor monitors the position of the camshaft (which controls valves), while the crankshaft position sensor monitors the position and speed of the crankshaft (which controls pistons). They work together to ensure the engine’s fuel injection and spark timing are perfectly synchronized.
Q7: How long do camshaft position sensors typically last?
A7: Camshaft position sensors are generally designed to last the lifetime of the vehicle. However, like any electronic component, they can fail prematurely due to heat, vibration, or manufacturing defects. Some can last well over 100,000 miles, while others might fail earlier.
Conclusion
A failing Subaru Forester camshaft position sensor can be a real headache, but thankfully, it’s a fixable problem. By choosing a high-quality replacement from our list, you can restore your Forester’s engine performance, eliminate those annoying warning lights, and get back to enjoying reliable, smooth drives. Always double-check compatibility with your specific vehicle year and model to ensure a perfect fit!
