5 Best 2015 GMC Terrain Camshaft Position Sensor Replacements for Optimal Performance
Is your 2015 GMC Terrain acting a bit sluggish? Maybe the check engine light popped on, or you’re experiencing rough idling and a struggle to start? These could all be tell-tale signs of a faulty camshaft position sensor. This small but mighty component plays a crucial role in your engine’s performance, ensuring everything runs smoothly and efficiently.
Finding the right replacement can feel like a chore, especially with so many options out there. That’s why we’ve put together a comprehensive guide to help you navigate the choices. We’ll review some of the top-rated camshaft position sensors compatible with your 2015 GMC Terrain, focusing on quality, reliability, and value. Let’s dive in and get your Terrain running like new!
Why a Healthy Camshaft Position Sensor is Crucial for Your GMC Terrain
Before we jump into the reviews, let’s quickly touch on why this sensor is so important. The camshaft position sensor (also known as a CMP sensor) works hand-in-hand with your crankshaft position sensor to tell your vehicle’s engine control unit (ECU) the precise position of the camshaft. This information is vital for the ECU to accurately time fuel injection and ignition, optimizing engine power, fuel efficiency, and emissions.
When your 2015 GMC Terrain camshaft position sensor goes bad, your vehicle might show symptoms like:
* Difficulty starting or intermittent stalling
* A noticeable drop in fuel economy
* Engine misfires or rough idling
* Reduced acceleration or power
* The illumination of your check engine light (often with codes like P0340, P0341, etc.)
Replacing a failing sensor isn’t just about clearing a dashboard light; it’s about restoring your vehicle’s proper function and preventing further, potentially more costly, engine issues down the road.

Buying Guide: Choosing the Right Camshaft Position Sensor
When picking a new camshaft position sensor for your 2015 GMC Terrain, consider these factors:
- Compatibility: This is paramount! Always double-check the product’s compatibility list against your vehicle’s make, model, year, and engine size. Referencing your original part’s OE (Original Equipment) number is the most reliable way to ensure a perfect fit.
- OEM vs. Aftermarket: OEM (Original Equipment Manufacturer) parts are identical to those installed in your car at the factory. Aftermarket parts are produced by other manufacturers and can offer good quality at a lower price. All the products reviewed here are quality aftermarket options designed to meet or exceed OEM specifications.
- Sensor Type & Quantity: Do you need just one sensor, or is it smart to replace both intake and exhaust sensors? Some kits offer bundles, which can be cost-effective if you need multiple related parts (like VVT solenoids or crankshaft sensors).
- Warranty: A good warranty offers peace of mind. Look for sensors that come with at least a 12-month warranty, signaling the manufacturer’s confidence in their product’s durability.
- Brand Reputation: While we’ve highlighted some reputable options, a quick search for customer reviews can give you insights into a brand’s reliability and customer support.
- Ease of Installation: Most camshaft position sensors are “plug-and-play,” meaning they connect directly without complex wiring. However, consider the sensor’s location on your Terrain; some might require more effort to access.

Frequently Asked Questions (FAQ)
Q1: What does a camshaft position sensor do in my 2015 GMC Terrain?
A: The camshaft position sensor monitors the rotational position of the camshaft and sends this data to the engine’s computer (ECU). The ECU uses this information, along with data from the crankshaft sensor, to precisely time fuel injection and ignition, optimizing engine performance, fuel economy, and emissions.
Q2: What are the common symptoms of a bad camshaft position sensor?
A: Common symptoms include the illumination of the check engine light (often with codes like P0340, P0341), hard starting, intermittent stalling, rough idling, engine misfires, poor acceleration, and reduced fuel economy.
Q3: Can I drive my 2015 GMC Terrain with a bad camshaft position sensor?
A: While your Terrain might still run, it’s not recommended to drive with a faulty camshaft position sensor for long. It can lead to severe engine performance issues, decreased fuel efficiency, and potentially cause damage to other engine components over time due to improper timing. It’s best to replace it as soon as possible.
Q4: How difficult is it to replace a 2015 GMC Terrain camshaft position sensor myself?
A: For many, replacing a camshaft position sensor is a moderately easy DIY task. It typically involves locating the sensor, disconnecting its electrical connector, unbolting it, and then installing the new sensor in reverse order. However, accessibility can vary, and if you’re uncomfortable with auto repairs, professional help is always an option.
Q5: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A: Both are vital engine sensors, but they monitor different components. The camshaft position sensor tracks the camshaft’s rotation, which dictates valve timing. The crankshaft position sensor monitors the crankshaft’s rotation, which dictates piston position. Together, they provide the ECU with a complete picture of the engine’s rotation and stroke for precise timing.
Q6: Are aftermarket camshaft position sensors as good as OEM parts?
A: Many aftermarket camshaft position sensors are manufactured to meet or even exceed OEM specifications. Reputable aftermarket brands offer high-quality, reliable parts that can perform just as well as OEM sensors, often at a more affordable price. Always check product reviews and warranties when choosing an aftermarket option.
Q7: How often should I replace my 2015 GMC Terrain camshaft position sensor?
A: There’s no fixed replacement interval for camshaft position sensors. They are typically replaced only when they fail. However, if you’re experiencing the symptoms mentioned above, or if diagnostic trouble codes point to a sensor issue, it’s time for a replacement.
Q8: What diagnostic trouble codes (DTCs) are associated with a faulty camshaft position sensor?
A: Common DTCs include P0340 (Camshaft Position Sensor Circuit Malfunction), P0341 (Camshaft Position Sensor Circuit Range/Performance), P0342 (Camshaft Position Sensor Circuit Low Input), P0343 (Camshaft Position Sensor Circuit High Input), and sometimes P0344 (Camshaft Position Sensor Circuit Intermittent).
