5 Top 2006 Altima Camshaft Position Sensor Options for a Smooth Ride
If your trusty 2006 Nissan Altima is showing signs of a rough idle, struggling to start, or has that dreaded “Check Engine” light glowing on your dashboard, chances are you might be dealing with a faulty camshaft position sensor. This little component plays a big role in your engine’s precise timing, ensuring everything runs smoothly. When it goes bad, it can cause a whole host of headaches.
Finding the right replacement can feel like a chore, especially with so many options out there. That’s why we’ve put together a list of the top 5 camshaft position sensor options specifically for your 2006 Altima. We’ll break down what makes each one stand out, so you can pick the perfect fit and get your Altima purring again.
What Does a Camshaft Position Sensor Do, Anyway?
Before we dive into the products, let’s quickly explain why this sensor is so vital. Your engine’s camshafts control the opening and closing of the valves, letting air in and exhaust out. The camshaft position sensor monitors the speed and position of these camshafts, sending crucial data to your car’s Engine Control Unit (ECU). The ECU then uses this information to precisely time fuel injection and ignition, ensuring optimal engine performance and fuel efficiency. A malfunctioning sensor throws this timing off, leading to various driveability issues.
Let’s get into the reviews!

4. A-Premium 2-PC Engine Camshaft Position Sensor Compatible with (L4 Altima)
Important Note for 2006 Altima V6 Owners: While this A-Premium product is listed for the Nissan Altima 2002-2006, it’s specifically for the L4 2.5L engine models. Furthermore, the product features section oddly states “2x Crankshaft Position Sensors” while the title and overall category point to camshaft sensors. If you have the common V6 3.5L 2006 Altima, this might not be the correct part for your camshaft position sensor needs. However, if you indeed have an L4 Altima and are looking for a crankshaft sensor (despite the title), or are willing to clarify with the seller, it offers a dual-pack solution.
Key Features:
– Specifically compatible with Nissan Altima 2002-2006 L4 2.5L and other L4 Nissan/Suzuki models.
– Reference numbers include PC464, 237316N202, etc.
– Features 3 pins and a blade terminal.
– Package quantity: 2 sensors (labeled as “Crankshaft Position Sensors” in features).
– One-year unlimited-mileage guarantee.
Pros:
– Convenient 2-pack for specific L4 applications.
– Direct OE replacement for ease of installation.
– Backed by a solid one-year warranty.
Cons:
– Crucially, designed for L4 Altima engines, not the more common V6 3.5L relevant to many “2006 Altima camshaft position sensor” searches.
– Conflicting information in the product description (titled “Camshaft” but features list “Crankshaft”).
– May cause confusion for V6 Altima owners.
User Impressions: For those with the compatible L4 Altima, if this sensor indeed fixes their issue, users typically find A-Premium products to be a decent aftermarket choice. However, the fitment and product description discrepancy can be a source of frustration or return for buyers looking for the V6 camshaft sensor.
5. A-Premium Engine Camshaft Position Sensor Compatible with (Single L4 Altima)
Similar to the previous A-Premium offering, this particular camshaft position sensor is also designed for the L4 2.5L Nissan Altima, specifically the 2002-2006 models. Unlike the dual pack, this comes as a single sensor. If your 2006 Altima is the L4 variant and you’ve diagnosed only one camshaft position sensor as faulty, this single unit could be a more economical and precise replacement for your needs. It maintains A-Premium’s commitment to direct fit and a reliable warranty.
Key Features:
– Compatible with Nissan Altima 2002-2006 L4 2.5L and various other L4 Nissan/Suzuki models.
– Reference numbers include PC464, 237316N202, etc.
– Features 3 pins and a blade terminal.
– Package quantity: 1x Camshaft Position Sensor.
– One-year unlimited-mileage guarantee.
Pros:
– Single sensor option, ideal if only one is needed for L4 models.
– Direct OE replacement for easy installation.
– Reliable A-Premium brand quality with a one-year warranty.
Cons:
– Only compatible with L4 Altima engines, not the V6 3.5L.
– Not suitable if your V6 engine requires two camshaft sensors or a crankshaft sensor.
User Impressions: For owners of the L4 2006 Altima who’ve correctly identified a single faulty camshaft sensor, this product is often a straightforward and effective fix. Users appreciate the ease of installation and the resolution of their vehicle’s symptoms, affirming its role as a solid replacement part.
Frequently Asked Questions (FAQ)
Q1: What are the common symptoms of a failing 2006 Altima camshaft position sensor?
A: Common symptoms include the “Check Engine” light illuminating, difficulty starting your car (especially when warm), rough idling, stalling, poor acceleration, and misfires. You might also notice a decrease in fuel economy.
Q2: Can I replace the 2006 Altima camshaft position sensor myself?
A: Yes, it’s generally considered a DIY-friendly repair for many car owners with basic mechanical skills and tools. The sensors are usually located on the cylinder heads (for V6 models, often one on each bank) or near the timing cover for L4 models. Always consult your vehicle’s service manual for exact locations and steps.
Q3: Where are the camshaft position sensors located on a 2006 Altima V6 3.5L?
A: For the V6 3.5L Altima, there are typically two camshaft position sensors: one on the passenger side (Bank 1) and one on the driver’s side (Bank 2) of the engine, usually towards the back of the cylinder heads. It’s often recommended to replace both if one goes bad, as the other might not be far behind.
Q4: Is it safe to drive my 2006 Altima with a bad camshaft position sensor?
A: While your car might still run, it’s not advisable to drive with a faulty camshaft position sensor for long. It can lead to unpredictable engine behavior, stalling in traffic, reduced power, and potentially more serious engine damage over time due to improper timing or increased stress on other components.
Q5: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A: Both are vital for engine timing. The camshaft position sensor monitors the position of the camshafts, which control valve opening/closing. The crankshaft position sensor monitors the position and speed of the crankshaft, which drives the pistons. Together, they give the ECU the full picture for precise fuel injection and ignition. Some systems are more reliant on one over the other, but both are critical.
Q6: How much does it typically cost to replace a 2006 Altima camshaft position sensor?
A: The cost for the sensor itself usually ranges from $20 to $60 for an aftermarket part. If you do it yourself, that’s your only cost. If you take it to a mechanic, labor costs can add another $80-$200, depending on your location and the shop’s rates, as it’s a relatively quick job.
Q7: How long do camshaft position sensors typically last?
A: There’s no fixed lifespan for a camshaft position sensor; some can last the life of the vehicle, while others might fail prematurely. Factors like extreme temperatures, vibrations, and electrical issues can affect their longevity. They are wear-and-tear items that eventually need replacement.
Conclusion
A faulty camshaft position sensor can really throw a wrench in your 2006 Altima’s performance, but thankfully, it’s a fixable issue. Choosing the right replacement sensor is key to getting your car back to its smooth, reliable self. Whether you need a single sensor for an L4 model or a comprehensive kit for your V6, there’s a quality option out there. By picking one of the reviewed products, you’ll be well on your way to silencing that check engine light and enjoying a much smoother ride. Safe driving!
