10 Top 2009 Chevy Cobalt Camshaft Position Sensor Replacements Reviewed
Is your trusty 2009 Chevy Cobalt acting a bit sluggish? Perhaps you’ve noticed the dreaded “check engine” light glowing on your dashboard, or maybe your car just isn’t starting as smoothly as it used to. These could all be tell-tale signs of a failing camshaft position sensor. This tiny but mighty component plays a crucial role in your engine’s performance, ensuring everything runs like a well-oiled machine.
But with so many options out there, how do you pick the right one for your 2009 Chevy Cobalt camshaft position sensor replacement? Don’t sweat it! We’ve done the heavy lifting for you, reviewing the top 10 camshaft position sensors and related components that are perfect for your ride. We’ll break down what makes each product stand out, their pros and cons, and what real users have to say. Let’s dive in!
Why Your 2009 Chevy Cobalt Needs a Good Camshaft Position Sensor
The camshaft position sensor (CMP sensor) is a critical part of your engine’s electronic control system. It monitors the rotational speed and position of the camshaft, sending this vital data to your vehicle’s Engine Control Unit (ECU). The ECU then uses this information to precisely control fuel injection and ignition timing.
When this sensor goes bad, your 2009 Chevy Cobalt might experience a range of issues, including:
* Check Engine Light (CEL): Often accompanied by specific diagnostic trouble codes (DTCs) like P0340 or P0341.
* Rough Idle or Stalling: The engine struggles to maintain a steady RPM.
* Hard Starting: It takes longer or multiple attempts to get the engine to turn over.
* Reduced Fuel Economy: Your car might be guzzling more gas than usual.
* Decreased Engine Performance: Noticeable loss of power or acceleration.
Replacing a faulty sensor is not only important for fixing these symptoms but also for maintaining your vehicle’s overall health and avoiding more expensive repairs down the line.

Buyer’s Guide: What to Look For in a 2009 Chevy Cobalt Camshaft Position Sensor
When you’re shopping for a new camshaft position sensor for your 2009 Chevy Cobalt, keep these key factors in mind to make the best choice:
- Compatibility: This is paramount. Double-check the product’s fitment list to ensure it explicitly mentions your 2009 Chevy Cobalt, specifically the year and engine size (e.g., 2.2L, 2.4L, or 2.0L Turbo). Cross-referencing OEM part numbers (like 12577245 or 917-720) with your original part is also a smart move.
- Type of Sensor: Some products are just the camshaft position sensor, while others are comprehensive kits including VVT actuators or crankshaft sensors. Diagnose your specific issue (e.g., via OBD-II scanner) to determine what you truly need. Don’t pay for parts you don’t need, but also don’t miss an opportunity to address related issues if the diagnosis points that way.
- Quality and Material: Look for sensors made from durable, high-quality plastic and metal components. While all products here are aftermarket, a good manufacturer will use materials designed to withstand engine heat and vibrations for long-term reliability.
- Ease of Installation: Many of these are “direct replacement” or “plug-and-play,” which is great for DIYers. If you’re not comfortable with auto repairs, factor in the cost of professional installation.
- Warranty: A good warranty (e.g., 12-18 months) indicates the manufacturer’s confidence in their product and offers peace of mind.
- User Reviews: Real-world feedback from other 2009 Chevy Cobalt owners can be incredibly valuable. Look for comments on fitment, effectiveness in solving symptoms, and product longevity.
Frequently Asked Questions (FAQ)
Q1: What exactly does a camshaft position sensor do in my 2009 Chevy Cobalt?
A1: The camshaft position sensor monitors the exact position and rotational speed of your engine’s camshaft. This information is sent to the Engine Control Unit (ECU), which uses it to precisely time fuel injection and ignition spark, ensuring your engine runs smoothly and efficiently.
Q2: What are the common symptoms of a failing 2009 Chevy Cobalt camshaft position sensor?
A2: Common symptoms include the illumination of the “Check Engine Light” (often with codes like P0340 or P0341), difficulty starting the car, rough idling, engine stalling, decreased fuel efficiency, and a noticeable loss of power or acceleration.
Q3: Can I replace the camshaft position sensor myself on my 2009 Chevy Cobalt?
A3: For many 2009 Chevy Cobalt models, replacing the camshaft position sensor is considered a relatively straightforward DIY task. It usually involves locating the sensor, disconnecting its electrical connector, unbolting it, and then installing the new one. Always consult your vehicle’s service manual or reliable online guides for exact steps and torque specifications.
Q4: Is there a difference between an intake and exhaust camshaft position sensor?
A4: Yes, many modern engines, including some found in the 2009 Chevy Cobalt (especially those with Variable Valve Timing or VVT), have both an intake and an exhaust camshaft, each with its own position sensor. While they perform similar functions, they are typically distinct parts and should not be interchanged. Always check your vehicle’s specific requirements.
Q5: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A5: Both are crucial for engine timing. The camshaft position sensor (CMP) tells the ECU the position of the camshaft (which controls valve opening/closing), while the crankshaft position sensor (CKP) tells the ECU the position and speed of the crankshaft (which dictates piston position). They work together to ensure precise engine operation.
Q6: Will a faulty camshaft position sensor damage my engine?
A6: While a faulty camshaft position sensor might not directly cause catastrophic engine damage immediately, ignoring the symptoms can lead to other issues. Poor engine timing can increase wear and tear, reduce fuel efficiency, cause misfires that harm the catalytic converter, and generally degrade overall engine health over time. It’s best to replace it promptly.
Q7: How do I verify the correct part number for my 2009 Chevy Cobalt camshaft position sensor?
A7: The best way is to physically inspect your current sensor for any stamped part numbers. Alternatively, use your car’s VIN (Vehicle Identification Number) at a dealership parts counter or a reputable online auto parts website to look up the correct OEM part number for your specific 2009 Chevy Cobalt model and engine.
