Chevrolet Equinox Camshaft Position Sensor Guide (2005-2020)
Having trouble starting your Equinox or dealing with a check engine light? Your camshaft position sensor could be the problem.
- Most Equinox engines from 2010-2020 have two camshaft sensors (intake and exhaust); verify the correct one before buying.
- Symptoms include a check engine light (P0340, P0341), hard starting, stalling, and rough running.
- Replacement is a good DIY job for most owners, typically requiring only a 10mm socket.
- For electronic parts on your Equinox, using an OEM brand like ACDelco or a reputable aftermarket equivalent is strongly recommended for reliability.
Symptoms of a Failing Camshaft Position Sensor in a Chevrolet Equinox
When the camshaft position sensor in your Equinox starts to go bad, you'll likely notice. Because the sensor is key to engine timing, a faulty one can cause several clear symptoms. The first sign for many owners is the Check Engine Light. The computer will store a trouble code, often P0340 or P0341, when it detects a problem with the sensor's signal.
You may also experience:
- Difficulty Starting: The engine might crank longer than usual before starting, or it might not start at all.
- Engine Stalling: The engine could shut off unexpectedly while driving or when stopped at an idle.
- Rough Idle: An unstable sensor signal can cause the engine to shake or run unevenly when idling.
- Poor Acceleration: Your Equinox might feel sluggish or hesitate when you press the gas pedal. 🎬 Watch a detailed breakdown of common camshaft sensor failure symptoms.
Don't Ignore the Signs
While you might be able to drive for a short time with a failing sensor, symptoms like stalling can be dangerous. It's best to address the issue promptly to avoid being stranded or causing further engine problems.
Choosing the Right Aftermarket Sensor
When it's time to replace the sensor, you'll find OEM (Original Equipment Manufacturer) parts and many aftermarket options. For GM vehicles, ACDelco is the OEM parts brand. Many mechanics and experienced owners recommend sticking with ACDelco or other high-quality brands like Delphi, Bosch, or NGK/NTK for electronic parts. Cheaper, no-name sensors have a reputation for failing early, which means you might have to do the job all over again. Aftermarket brands like "Replacement" can offer good value, but it's wise to choose a part that comes with a warranty.
Common Ordering Mistake
Many Equinox engines, especially the popular 2.4L and 1.5L 4-cylinders, have two camshaft position sensors: one for the intake camshaft and one for the exhaust. They can look identical but may have different part numbers. Always confirm which sensor you need to replace (based on the specific trouble code) and verify the part number for that position before ordering.
Generation and Engine Differences
The location of the sensor varies by your Equinox's engine and year.
- 2005-2009 (3.4L V6): These models have one sensor located on the left side of the engine, below the throttle body. 🎬 See how to replace the sensor on 2005-2009 3.4L models.
- 2010-2017 (2.4L 4-Cylinder): This common engine has two sensors. The intake sensor is under the high-pressure fuel pump cover, and the exhaust sensor is at the rear of the cylinder head, near the firewall. Replacing the exhaust sensor is more challenging due to its location.
- 2010-2017 (3.0L/3.6L V6): These engines also feature intake and exhaust sensors.
- 2018-2020 (1.5L/2.0L Turbo): The sensors are typically on the top right side of the engine, making them fairly easy to access. 🎬 Video guide for replacing sensors on 1.5L turbo engines.

Frequently Asked Questions
How many camshaft position sensors does my Equinox have?
It depends on your engine. The first-generation 3.4L V6 (2005-2009) has one sensor. Most later models with 4-cylinder or V6 engines (2.4L, 1.5L, 3.0L, 3.6L) have two sensors—one for intake and one for exhaust.
Is this a difficult repair to do myself?
For most Equinox models, this is a very DIY-friendly repair. The sensor is usually held in by a single 10mm bolt and has an electrical connector. The most difficult one to access is the exhaust sensor on the 2010-2017 2.4L engine, which is tucked behind the engine against the firewall. For most other locations, it should take less than an hour with basic tools.
What are the trouble codes for a bad camshaft sensor?
The most common codes are P0340 (Camshaft Position Sensor 'A' Circuit Malfunction) and P0341 (Camshaft Position Sensor 'A' Circuit Range/Performance). Code P0340 usually points to a problem with the intake sensor circuit. You may also see codes like P0342, P0343, P0365, or others depending on the specific fault.
Do I need a special tool to replace the sensor?
Usually, no. A basic ratchet with a 10mm socket is typically all that's needed to remove the bolt holding the sensor in place. A small pick or flathead screwdriver can be helpful for releasing the locking tab on the electrical connector.

The camshaft position sensor is a Hall-effect sensor that reads the position of the camshaft via a reluctor wheel. It sends a digital signal to the powertrain control module (PCM) to synchronize fuel injection and ignition timing. Most Equinox engines use two sensors, one for the intake cam and one for the exhaust cam.
