5 Top Camshaft Position Sensors for Your 2011 GMC Acadia
If your 2011 GMC Acadia is acting a bit sluggish, showing that dreaded “check engine” light, or simply struggling to start, a faulty camshaft position sensor could be the culprit. This small but mighty component plays a vital role in your engine’s smooth operation, making sure everything is timed just right. Replacing it can often be a straightforward fix that brings your Acadia back to its lively self.
But with so many options out there, how do you pick the right one? We’ve done the legwork for you! In this guide, we’ll break down the top 5 camshaft position sensors that are a great fit for your 2011 GMC Acadia, helping you make an informed decision and get your vehicle running smoothly again.
What is a Camshaft Position Sensor and Why is it Important for Your 2011 GMC Acadia?
Think of your engine’s camshaft position sensor (often abbreviated as CPS) as a conductor in a symphony orchestra. It meticulously monitors the exact position and speed of your engine’s camshaft – the part that opens and closes the valves. This crucial information is then sent to your vehicle’s engine control unit (ECU).
Why is this so important for your 2011 GMC Acadia? Because the ECU uses this data, along with information from the crankshaft position sensor, to precisely determine when to fire the spark plugs and inject fuel into the cylinders. Without accurate readings, your engine’s timing can go haywire, leading to a host of frustrating issues.
Common symptoms of a failing camshaft position sensor include:
- Illuminated “Check Engine Light” (often with specific diagnostic trouble codes like P0340 or P0341).
- Engine misfires or rough idle.
- Difficulty starting your vehicle, or prolonged cranking.
- Sudden stalling while driving.
- Reduced fuel economy or overall engine performance.
- Rough acceleration.
If you’re experiencing any of these, it’s a good idea to have your vehicle diagnosed. If the 2011 GMC Acadia camshaft position sensor is indeed the problem, replacing it sooner rather than later can prevent further damage and restore your ride’s optimal performance.

Buying Guide: What to Consider Before You Buy
Choosing the right camshaft position sensor for your 2011 GMC Acadia involves a few key considerations:
- Vehicle Fitment: This is paramount! Always double-check the product’s compatibility list against your specific vehicle’s year, make, model, and engine size (the 3.6L V6 is common for the Acadia). Comparing the OEM part number of your old sensor with the replacement’s listed numbers is the most reliable way to ensure a perfect fit.
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) parts are made by the same company that supplied the parts to GM when your Acadia was built. They’re typically high quality and guaranteed to fit, but often come at a premium price. Aftermarket parts, on the other hand, are made by other companies and can be more affordable. Quality can vary, so it’s wise to stick with reputable brands or those with good reviews.
- Warranty: A good warranty indicates the manufacturer’s confidence in their product. Look for sensors that offer at least a 1-year warranty for peace of mind.
- Included Components: Some kits include both camshaft and crankshaft position sensors, which can be a great value if you suspect both might need replacing or want to have spares.
Conclusion
A failing 2011 GMC Acadia camshaft position sensor can be a real headache, leading to frustrating engine problems. Thankfully, replacing it is often a manageable DIY task or a relatively inexpensive repair at a shop. By choosing one of the high-quality sensors reviewed above, you can confidently address the issue and get your Acadia running smoothly and reliably once again.

FAQ Section
Q1: What exactly does a camshaft position sensor do in my 2011 GMC Acadia?
A1: The camshaft position sensor monitors the exact rotational position and speed of your engine’s camshaft. This information is crucial for the engine control unit (ECU) to precisely time the fuel injection and spark plug firing, ensuring your engine runs efficiently and smoothly.
Q2: What are the common symptoms of a bad camshaft position sensor?
A2: Common symptoms include the “Check Engine Light” illuminating (often with codes like P0340), engine misfires, rough idle, difficulty starting (especially when the engine is warm), stalling, reduced fuel economy, and poor acceleration.
Q3: Can I drive my 2011 GMC Acadia with a bad camshaft position sensor?
A3: While your Acadia might still run with a failing sensor, it’s not recommended. Driving with a faulty sensor can lead to decreased engine performance, poor fuel efficiency, potential damage to other engine components due to incorrect timing, and increased emissions. It’s best to replace it as soon as possible.
Q4: Is it difficult to replace a camshaft position sensor on a 2011 GMC Acadia?
A4: For many 2011 GMC Acadia owners, replacing the camshaft position sensor is a relatively straightforward DIY task that requires basic tools. However, the exact location and ease of access can vary. Always consult your vehicle’s service manual or watch online tutorials specific to your Acadia model year before attempting the repair.
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 tracks the camshaft’s rotation (which controls valve opening/closing), while the crankshaft position sensor tracks the crankshaft’s rotation (which indicates piston position). Together, they provide the ECU with a complete picture of the engine’s precise position and movement.
Q6: Should I choose an OEM or aftermarket camshaft position sensor for my Acadia?
A6: OEM sensors guarantee an exact fit and often have higher quality control, but they are typically more expensive. Aftermarket sensors are more affordable and can offer great performance, but quality can vary between brands. For your 2011 GMC Acadia, a reputable aftermarket brand with good reviews and a warranty can be a cost-effective and reliable choice.
Q7: How much does it cost to replace a camshaft position sensor on a 2011 GMC Acadia?
A7: The cost of the sensor itself can range from $20 to $100+ depending on the brand and type (single sensor vs. kit). If you do it yourself, that’s your total cost. If you take it to a mechanic, labor costs typically range from $100 to $200, making the total cost anywhere from $120 to $300+.
