Frequently Asked Questions about the 2017 GMC Terrain Camshaft Position Sensor

Getting to know more about this vital component can help you keep your GMC Terrain running smoothly. Here are some common questions.

Q1: What does a camshaft position sensor do in my 2017 GMC Terrain?
A1: The camshaft position sensor is like a reporter for your engine. It tells the engine’s computer (ECU) the exact position of the camshaft, which controls the opening and closing of your engine’s valves. This information is crucial for the ECU to precisely time the fuel injection and spark plug firing, ensuring your engine runs efficiently and powerfully.

Q2: What are the common symptoms of a failing 2017 GMC Terrain camshaft position sensor?
A2: If your camshaft position sensor is going bad, you might notice a few warning signs. These often include the illumination of your check engine light (sometimes with specific codes like P0340 or P0341), difficulty starting your vehicle, rough idling, engine misfires, reduced fuel efficiency, or even sudden stalling while driving.

Q3: Can I drive my 2017 GMC Terrain with a bad camshaft position sensor?
A3: While your Terrain might still run with a faulty sensor, it’s not recommended to drive it for long. A failing sensor can lead to decreased performance, poor fuel economy, increased emissions, and potential damage to other engine components due to incorrect timing. It’s best to replace it as soon as possible.

Q4: Is replacing the camshaft position sensor a difficult DIY job for a 2017 GMC Terrain?
A4: For many 2017 GMC Terrain models, replacing the camshaft position sensor can be a relatively straightforward DIY task, especially for those with some mechanical experience. The sensor is usually easily accessible. However, always consult your service manual or a reliable online tutorial specific to your Terrain’s engine to ensure you follow the correct procedure and use the right tools. If you’re unsure, professional installation is always a safe bet.

Q5: How many camshaft position sensors does a 2017 GMC Terrain have?
A5: Most 2017 GMC Terrain models (especially those with the 2.4L 4-cylinder engine) typically have two camshaft position sensors: one for the intake camshaft and one for the exhaust camshaft. If you have the 3.6L V6 engine, it might have more, typically one for each camshaft (four in total). It’s always a good idea to check your specific model’s manual or visually inspect your engine.

Q6: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both are vital for engine timing, but they measure different things. The camshaft position sensor tracks the camshaft’s rotation, indicating valve timing. The crankshaft position sensor monitors the crankshaft’s rotation, indicating piston position and engine speed. Together, they provide the ECU with comprehensive data for optimal engine operation.

Q7: Will replacing the camshaft position sensor clear my check engine light?
A7: In most cases, yes! If a faulty camshaft position sensor was the root cause of your check engine light, replacing it should resolve the issue and the light should turn off after a few drive cycles, or you can manually clear the code with an OBD-II scanner.
