A Yukon Owner's Guide to the 2008-2015 Engine Camshaft Position Sensor
If your GMC Yukon is running rough or won't start, the camshaft sensor could be the problem.
- A bad camshaft sensor is a common cause for code P0340, hard starting, rough idle, and stalling.
- For reliability, choose an OEM (ACDelco) or premium aftermarket brand (Delphi, NTK) for this sensor.
- Always inspect the sensor's wiring and connector for damage before replacing the part itself.
- The sensor is in a tight spot, but replacement is a feasible DIY job with basic tools and patience.
Is Your Camshaft Position Sensor Failing?
A failing camshaft position sensor can cause a range of problems, from annoying to serious. The sensor sends a signal to the engine's computer to help it run correctly. When that signal is weak, incorrect, or gone, the computer gets confused. This can make your Yukon hard to start, run poorly, or even stall while you are driving. The most common sign is the check engine light coming on, often with the code P0340.

When it comes to electronic sensors, not all aftermarket brands are created equal. For a part this critical, choosing a quality brand can save you from doing the job twice. Owner and mechanic feedback strongly suggests using OEM or top-tier aftermarket brands for sensors.
Brand Quality Tiers
- Tier 1: OEM & Premium Aftermarket (Recommended)
These brands are either the original equipment manufacturer or have a strong reputation for quality that meets or exceeds OEM standards. For a critical sensor, this is the safest bet.
Brands: ACDelco (GM Original Equipment), Delphi - Tier 2: Reputable Aftermarket
These brands are known for producing reliable parts and are a solid choice if an OEM-level part isn't available or is out of budget.
Brands: NGK (NTK), Standard Ignition (Standard Motor Products), Hitachi, Holstein - Tier 3: Economy Brands
These brands focus on value. While they may work, their long-term reliability can be a concern for sensitive electronics. They might be a short-term fix, but failure rates can be higher.
Brands: Dorman, Walker Products, True Tech, Prenco, Global Parts

Frequently Asked Questions
Where is the camshaft position sensor located on a 2008-2015 GMC Yukon?
The sensor is located on the engine block, but its exact position can be tricky. On the 5.3L and 6.2L V8 engines, it is typically found on the front of the engine, below the water pump, near the timing cover. 🎬 Watch: How to locate and swap the sensor on a Yukon However, some service diagrams and videos show it at the top-rear of the engine block, near the firewall and oil pressure sensor. Access is very tight in either location. The front location requires working around the belts and pulleys, while the rear location may require removing the intake manifold for clear access, or working by feel behind the engine.
Can I replace the camshaft sensor myself?
Yes, this is a DIY-feasible job for someone comfortable working in tight spaces. The job requires basic tools, mainly a 10mm socket and an extension. The main challenge is accessing the sensor, which often involves working "blind" by feel. 🎬 See this step-by-step replacement guide for GM 5.3L engines Be sure to lubricate the O-ring on the new sensor with clean engine oil before installation.
Are there any recalls for the camshaft position sensor on this Yukon?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls or specific Technical Service Bulletins (TSBs) for the camshaft position sensor on the 2008-2015 GMC Yukon.
Should I buy a cheap aftermarket sensor?
It is not recommended. Mechanics and experienced owners strongly advise using an OEM (ACDelco) or a premium aftermarket (Delphi, NTK) sensor. Cheaper sensors have a higher reported failure rate. The labor involved in replacing the sensor, especially if you pay a shop, makes it worthwhile to spend a little extra on a quality part to ensure you only have to do the job once.
