Chevrolet Equinox 2005-2024 Engine Camshaft Position Sensor Guide
Having starting trouble or a rough idle? Your Equinox's camshaft position sensor could be the problem.
- A bad camshaft sensor on an Equinox causes hard starting, stalling, rough idle, and a check engine light.
- For GM electronics, sticking with ACDelco or Delphi brands is highly recommended for long-term reliability.
- Most Equinox engines (2.4L, 1.5L) have two sensors (intake and exhaust); verify which one you need before ordering.
- Replacement is a feasible DIY job for most owners, typically requiring only basic tools and less than an hour.
Symptoms of a Failing Camshaft Position Sensor
When a camshaft position sensor in your Equinox starts to fail, the signs can range from annoying to leaving you stranded. Because the sensor's signal is vital for engine timing, a bad sensor can cause several noticeable issues.
- Check Engine Light: This is often the first sign. The computer detects a problem with the sensor's signal and triggers a warning light. Common trouble codes include P0340, P0341, P0342, and P0343. 🎬 Learn more about the common symptoms of a failing sensor.
- Difficulty Starting: The engine may crank for a long time before it starts, or it might not start at all. The computer needs to see the camshaft position to initiate the starting sequence.
- Engine Stalling: The engine may suddenly shut off while you're driving or idling at a stoplight. This happens when the computer loses the sensor signal completely.
- Rough Idle and Misfires: An unstable signal can cause incorrect timing, leading to a shaky, vibrating idle and engine misfires.
- Poor Acceleration: You might notice your Equinox feels sluggish or hesitates when you press the gas pedal. Incorrect timing reduces engine power and efficiency. 🎬 Watch this detailed guide on testing and fixing camshaft sensor symptoms.
Choosing the Right Aftermarket Sensor
When replacing the camshaft position sensor, you have a choice between OEM (Original Equipment Manufacturer) and various aftermarket brands. For a critical electronic part like this, quality matters.
Pro Tip: Many Equinox owners and mechanics strongly recommend using either genuine GM parts or high-quality OEM-supplier brands for electronic sensors. Cheaper, lower-quality sensors are known to fail prematurely, causing you to do the job twice.
Brand Quality Tiers for Chevrolet Equinox
- Tier 1 (OEM & Premium Aftermarket): ACDelco is the genuine GM parts brand and the safest bet for reliability and perfect fit. Delphi is another excellent choice, as they are often the original manufacturer for GM's electronic parts. These brands are engineered to meet the original factory specifications.
- Tier 2 (Reputable Aftermarket): Brands like Bosch, NGK/NTK, and Hitachi have a strong reputation for producing quality electronic components that are reliable alternatives to OEM parts. Standard Motor Products (SMP) is also a well-regarded brand in the professional mechanic community.
- Tier 3 (Economy): Brands like Dorman, Walker Products, and others offer a more budget-friendly option. While they can be a good value, forum discussions suggest that for sensitive electronics on GM vehicles, their reliability can be inconsistent. Some owners report these parts failing within months, leading back to the original problem.
Cost of Replacing the Sensor
The cost can vary depending on the brand you choose and whether you do the work yourself or hire a professional.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Sensor | $20 - $83 |
| New OEM (ACDelco) Sensor | $50 - $90 |
| Shop Labor | $75 - $150 |
Known Issues and Generation Differences
The location and replacement procedure for the camshaft position sensor varies depending on your Equinox's engine and year.
- 2005-2009 (3.4L V6): The sensor is located on the left side of the engine, underneath the throttle body. 🎬 See how to replace the sensor on 2005-2009 3.4L models.
- 2010-2017 (2.4L 4-Cylinder): This popular engine has two camshaft position sensors—one for the intake cam and one for the exhaust cam. The intake sensor is under the high-pressure fuel pump cover, and the exhaust sensor is at the rear corner of the cylinder head. There is a GM Technical Service Bulletin (TSB #17-NA-098) for 2010-2012 models that notes rough running and stalling could be caused by failing camshaft position actuator solenoids, which can set similar codes (P0011, P0014). It's important to diagnose the issue correctly.
- 2018-2024 (1.5L Turbo): These engines also have intake and exhaust sensors, located on the top right side of the engine, making them relatively easy to access and replace. A TSB from GM (#21-NA-268) addresses a potential no-start or extended crank condition on these engines, which could be related to the exhaust camshaft reluctor ring and may set codes like P0014 or P0365.
Common Ordering Mistake: Many engines, like the 2.4L and 1.5L, use two sensors (intake and exhaust). They may look similar but can have different part numbers. Always verify the correct part for the specific position you are replacing.
Frequently Asked Questions (FAQ)
How many camshaft position sensors does my Equinox have?
It depends on your engine. The 3.4L V6 (2005-2009) typically has one. Most 4-cylinder engines, like the 2.4L (2010-2017) and 1.5L/2.0L Turbo (2018-2024), have two sensors: one for the intake camshaft and one for the exhaust camshaft.
Can I replace the camshaft position sensor myself?
Yes, for most Equinox models, this is a DIY-friendly job. It usually involves removing a single bolt and an electrical connector. On later models like the 1.5L, the sensors are easily accessible on top of the engine. On the 2.4L engine, the intake sensor requires removing a fuel pump cover, which adds a few steps. The difficulty is generally low, requiring basic hand tools.
What's the difference between a camshaft sensor and a crankshaft sensor?
They work together. The camshaft sensor tracks the position of the top part of the engine (valves), while the crankshaft sensor tracks the position of the bottom part (pistons). The ECM compares signals from both to ensure the engine is perfectly timed. A failure in either can cause similar symptoms.
Are there any recalls for the Equinox camshaft position sensor?
A search of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls for the camshaft position sensor itself across the 2005-2024 model years. However, several Technical Service Bulletins (TSBs) have been issued related to camshaft actuator solenoids and other timing components that can cause similar symptoms and codes.

The Chevrolet Equinox uses Hall-effect sensors that generate a digital square wave signal for the ECM. Most 4-cylinder engines use two separate sensors for the intake and exhaust camshafts. The sensor is typically held in place by a single 10mm bolt.
