GMC Canyon (2014-2022) Engine Camshaft Position Sensor Replacement Guide
Fix stalling and check engine lights by learning to identify a bad camshaft position sensor and choosing the right replacement for your truck.
- A failing sensor will likely trigger a check engine light with codes P0340, P0341, P0345, or P0346.
- The 3.6L V6 engine has four sensors, while the 2.5L I4 has two; replacement is a simple DIY job with basic tools.
- For reliability, stick with OEM (ACDelco) or premium aftermarket brands like Delphi for this critical electronic part.
- Before replacing sensors, always check your engine oil level, as low oil can cause similar symptoms and codes.
Symptoms of a Failing Camshaft Position Sensor
A bad camshaft position sensor will almost always trigger the check engine light, but other symptoms can help you confirm the problem before you buy parts. You might notice one or more of these issues with your Canyon:
- Check Engine Light: The most common sign is an illuminated check engine light. Codes like P0340, P0341, P0345, or P0346 are common for camshaft sensor circuit issues. 🎬 Watch how these codes were diagnosed and solved on a Colorado.
- Difficulty Starting: The engine may crank for a long time before it starts, or it might not start at all.
- Engine Stalling: The truck may stall unexpectedly, either while driving or when idling at a stop.
- Rough Idle and Misfires: The engine may run rough, shake, or shudder because the timing for spark and fuel is incorrect.
- Reduced Power and Acceleration: Your truck may feel sluggish and have trouble accelerating because the engine isn't running efficiently.
Choosing the Right Aftermarket Sensor for Your Canyon
When it comes to electronic sensors, quality matters. While a cheaper part might be tempting, it can fail prematurely and cause the same problems to return. For a critical sensor like this, it's best to stick with reputable brands.
Aftermarket Brand Quality Tiers
| Tier | Brands | Notes |
|---|---|---|
| Premium Aftermarket / OEM | ACDelco, Delphi | ACDelco is the original GM parts brand, offering the same quality as the part your truck came with. Delphi is often the original manufacturer for GM and is considered an equivalent, high-quality choice. Choosing one of these is the safest bet for reliability. |
| Reputable Aftermarket | NGK, Standard Ignition (SMP), Hitachi, Walker Products | These brands have a long-standing reputation for producing reliable electronic components. They offer a good balance of quality and price and are generally a safe alternative to OEM parts. |
| Budget Options | Dorman, Holstein, and others | While these brands offer a more affordable price point, forum discussions suggest a higher risk of early failure or out-of-the-box issues with critical sensors. They may be suitable for a temporary fix, but long-term reliability can be a concern. |
Cost of Replacing a Camshaft Position Sensor
The cost to replace a camshaft position sensor on a 2014-2022 GMC Canyon can vary. The 3.6L V6 engine has four sensors, while the 2.5L I4 has two. This table reflects the cost for a single sensor replacement.
| Item | Estimated Cost |
|---|---|
| New OEM (ACDelco) | $50 - $92 |
| New Aftermarket | $18 - $83 |
| Shop Labor | $60 - $120 |
| Total Professional Replacement | $78 - $203 |
Pro Tip: Check Your Oil
Before you replace any sensors, check your engine oil level and condition. Low or dirty oil can cause issues with the variable valve timing (VVT) system, which can sometimes trigger camshaft-related trouble codes. An oil change is much cheaper than replacing sensors you might not need.
Frequently Asked Questions (FAQ)
Where is the camshaft position sensor located on a GMC Canyon?
The location depends on your engine. On the 3.6L V6, there are four sensors located at the back of the cylinder heads, near the firewall. 🎬 See this video for the exact sensor locations on the V6. Two are for the intake camshafts and two are for the exhaust. On the 2.5L I4, there are two sensors, also typically located on the cylinder head. Accessing the sensors on the V6 can be tight, and may require removing the engine cover or air intake for easier access.
How many camshaft position sensors does my 2014-2022 GMC Canyon have?
If you have the 3.6L V6 engine, your truck has four camshaft position sensors (two intake, two exhaust). If you have the 2.5L 4-cylinder engine, you have two sensors (one intake, one exhaust).
Can I replace the sensor myself?
Yes, this is a very DIY-friendly job for most home mechanics. The sensor is typically held in by a single 10mm bolt and has one electrical connector. The main challenge is reaching the sensors, especially on the V6 engine where they are at the rear. Basic hand tools like a socket wrench and screwdriver are all that's needed.
Is there a recall for the camshaft position sensor?
There are no specific recalls on the NHTSA website for the camshaft position sensor itself for the 2014-2022 GMC Canyon. However, GM issued a special coverage program (N232430470) for the 2020 model year Canyon for a related part, the bank 2 exhaust camshaft position actuator valve solenoid, extending the warranty to 15 years or 150,000 miles for that specific component.
