Chevrolet Caprice Engine Camshaft Position Sensor: A Complete Guide (2011-2017)
Having starting problems or a rough idle in your 2011-2017 Caprice? Your camshaft position sensor might be the culprit.
- Confirm your engine (3.6L V6 or 6.0L V8) before buying; the V6 has four sensors while the V8 has one.
- For best reliability, choose OEM-supplier brands like ACDelco or Delphi, as sensors are a critical electronic component.
- A fault code like P0341 doesn't automatically condemn the sensor; inspect the wiring and connector for damage first.
- Replacement is a simple DIY task for many, typically requiring only a 10mm socket and about 30 minutes.
Is Your Caprice Showing Signs of a Bad Camshaft Sensor?
A failing camshaft position sensor in the 2011-2017 Chevrolet Caprice, whether it has the 3.6L V6 or the 6.0L V8, will usually give you some clear warning signs. Because this sensor is critical for engine timing, a bad signal can cause a variety of problems, from annoying to serious. You might notice one or more of the following issues:
- Check Engine Light: This is often the first sign. The computer will store a trouble code, typically in the P0340 to P0349 range.
- Engine Won't Start: The engine may crank but refuse to start because the computer doesn't have the camshaft position data needed for spark and fuel.
- Hard Starting: The vehicle might take longer than usual to start, especially when the engine is warm.
- Rough Idle and Stalling: The engine may run poorly, idle erratically, or stall unexpectedly while driving or at a stop.
- Poor Acceleration: You may feel hesitation or a lack of power when you press the gas pedal.
Important Note for Caprice Owners
The 2011-2017 Caprice was available with two main engines: the 3.6L LFX V6 and the 6.0L L77 V8. The V8 engine has one camshaft position sensor. The V6 engine has four camshaft position sensors (two intake and two exhaust). Always confirm your engine type before ordering parts.
Choosing the Right Aftermarket Sensor
When it comes to engine sensors, not all aftermarket brands are created equal. For a critical part like the camshaft position sensor, quality and reliability are key. Here’s a breakdown of available brands to help you choose.
Tier 1: OEM and OEM-Equivalent Brands
These brands are either the original equipment manufacturer for GM or are known to produce parts that meet or exceed OEM specifications. They are the most reliable choice for a direct, trouble-free replacement.
- ACDelco: As GM's own parts brand, ACDelco Genuine GM parts are the true original equipment. Their "Gold" line is also a high-quality aftermarket option. For maximum peace of mind, this is the top choice.
- Delphi: Delphi was once part of GM and has a long history of being an OEM supplier for their electronics. Many consider Delphi sensors to be of the same quality as the original factory part, often at a slightly lower price.
Tier 2: Reputable Aftermarket Brands
These companies are well-established in the aftermarket and have a strong reputation for producing quality electronic components. They offer a great balance of price and performance.
- NGK (NTK): Known for their spark plugs, NGK's sensor division, NTK, produces high-quality engine management sensors that are well-regarded by professional mechanics.
- Hitachi: A major OEM supplier for many Japanese brands, Hitachi also produces reliable sensors for a wide range of vehicles, including GM models.
- Standard Ignition (Standard Motor Products): A long-standing American company that specializes in engine management parts. Their sensors are a trusted choice in the repair industry.
Tier 3: Value-Oriented Brands
These brands focus on providing a more affordable alternative. While they can offer significant savings, quality can sometimes be inconsistent compared to the higher-tier brands. They can be a good option for a budget-conscious repair, but be aware of the potential trade-offs.
- Dorman: Known for making a huge variety of replacement parts. Their quality on sensors can be hit-or-miss, but they are a popular choice due to wide availability.
- Walker Products, Holstein, Prenco, True Tech, Global Parts: These brands fall into the economy category. They provide a functional replacement at a low cost, but may not have the same longevity or precise signaling as premium options.
Pro Tip: Check the Wiring First
Before you replace the sensor, always inspect the wiring harness and connector. A loose connection, corroded pin, or damaged wire can cause the same symptoms and fault codes as a bad sensor. A quick visual check can save you from replacing a perfectly good part.

Frequently Asked Questions
How many camshaft sensors does my 2011-2017 Caprice have?
It depends on your engine. The 6.0L V8 has one camshaft position sensor. The 3.6L V6 has four sensors in total: an intake and an exhaust sensor for each cylinder bank.
Can I replace the camshaft sensor myself?
Yes, this is a DIY-friendly job for most home mechanics. The sensor is usually held in by a single 10mm bolt and is located on the front of the engine for the V8 or on the front/rear of the cylinder heads for the V6. The main challenge is often just accessing it. Always disconnect the negative battery terminal before starting work.
Does a P0341 code always mean the sensor is bad?
Not always. A P0341 code means the sensor's signal is out of the expected range or performance. While a faulty sensor is the most common cause, the issue could also be related to wiring problems, a stretched timing chain, or issues with the variable valve timing (VVT) system.
Are there any recalls for the camshaft sensor on the Caprice?
No, there are no specific recalls from GM or NHTSA for the camshaft position sensor on the 2011-2017 Chevrolet Caprice. There is a Special Coverage Adjustment (TSB 14588A) for the engine cooling fan motor on police patrol vehicles due to premature wear from extended idling, but it is unrelated to the camshaft sensor.
