Guide to the 2006-2011 Chevrolet HHR Engine Camshaft Position Sensor

Understanding Camshaft Position Sensor Failure in Your HHR

When a camshaft position sensor fails on a 2006-2011 Chevrolet HHR, the engine's computer (ECM) loses track of where the camshaft is in its rotation. This can cause a variety of noticeable engine problems. Because the sensor's signal is essential for timing fuel delivery and spark, a bad sensor can make your vehicle run poorly or even leave you stranded.

Key Failure Symptoms

A failing camshaft position sensor can mimic other engine problems, but certain symptoms are very common for this specific part on the HHR. 🎬 Watch a breakdown of common symptoms of a bad sensor. You might experience one or more of the following:

• Check Engine Light: This is often the first sign. The ECM will store a trouble code, most commonly P0340, P0341 (intake sensor issues), P0365, or P0366 (exhaust sensor issues).
• Difficulty Starting: The engine may crank for a long time before it starts, or it may not start at all.
• Engine Stalling: The engine can shut off unexpectedly, sometimes while you are driving, which is a serious safety concern.
• Rough Idle and Misfires: Your HHR may vibrate or shake at a stop, and the engine can feel like it's sputtering.
• Poor Acceleration: You may notice a significant loss of power, making the car feel sluggish.

Important Note: Many HHR owners and even some mechanics confuse the camshaft position sensors with the camshaft position actuator solenoids (also called VVT solenoids). The solenoids are a more common failure point and cause similar symptoms. Always diagnose the problem correctly using the specific trouble code before buying parts.

Choosing the Right Aftermarket Sensor

When it comes to electronic sensors for your HHR, quality matters. While saving money is tempting, a cheap, low-quality sensor can fail quickly, leaving you with the same problem. Here’s a breakdown of available brands to help you choose.

Tier 1: OEM and OEM-Equivalent Brands

• ACDelco: As the original equipment manufacturer for GM, this is the same part your HHR came with from the factory. For critical electronics, ACDelco is a reliable, though often more expensive, choice.
• Delphi: Delphi was a major parts supplier for General Motors. Their sensors are widely considered to be of OEM quality and are often a more affordable alternative to ACDelco without sacrificing reliability.

Tier 2: Reputable Aftermarket Brands

• NGK (NTK): Known for their ignition products, NTK (the sensor division of NGK) produces high-quality sensors that are engineered to meet or exceed OEM specifications.
• Standard Ignition (SMP): A long-standing brand in the aftermarket, Standard Ignition offers parts that are a dependable alternative to OEM.
• Hitachi: Hitachi is another established OEM supplier for many car brands and is known for producing reliable electronic components.

Tier 3: Economy Brands

• Dorman: Dorman offers a wide range of aftermarket parts and is often a budget-friendly option. However, forum discussions show mixed reviews on the longevity of their electronic sensors.
• Other Brands: Brands like Walker Products, Holstein, URO Parts, and others fall into the value category. They can be a good choice for a budget repair, but may not offer the same long-term durability as premium brands.

Typical Replacement Costs

The cost to replace a camshaft position sensor on a 2006-2011 HHR is reasonable, especially if you do it yourself. The job is simple and requires basic tools.
