8 Top 04 Nissan Maxima Camshaft Position Sensor Replacements: Keep Your Engine Running Smoothly!
Has your trusty 2004 Nissan Maxima been giving you trouble lately? Perhaps you’ve noticed a nagging check engine light, erratic idling, or even a sudden stall in traffic. These symptoms can be incredibly frustrating, and often, the culprit points to a faulty 04 Nissan Maxima camshaft position sensor. This tiny but mighty component plays a vital role in your engine’s performance, ensuring everything runs like a well-oiled machine.
If you’re experiencing these issues, it’s likely time for a replacement. But with so many options out there, how do you pick the right one? Don’t sweat it! We’ve done the legwork for you, diving deep into the best aftermarket options available to get your Maxima back on the road, running smoothly and reliably.
Understanding Your Camshaft Position Sensor
Before we dive into the reviews, let’s quickly explain what a camshaft position sensor (CPS) does. Essentially, it’s one of your engine’s crucial “eyes.” It monitors the precise rotational speed and position of your engine’s camshafts, sending this critical data to the Engine Control Unit (ECU). The ECU then uses this information to perfectly time the fuel injection and spark plug firing, ensuring your 3.5L V6 engine (the VQ35DE) is running at peak efficiency.
Common Symptoms of a Failing CPS:
* Check Engine Light (CEL): This is often the first sign, with error codes like P0340 (camshaft position sensor circuit malfunction – Bank 1) or P0345 (Bank 2).
* Hard Starting: Your car might crank for longer than usual before firing up.
* Engine Misfires or Rough Idle: The engine might feel shaky or run unevenly, especially at idle.
* Poor Acceleration or Stalling: Your Maxima might hesitate when you hit the gas, or even stall out completely.
* Decreased Fuel Economy: If the sensor isn’t providing accurate data, your engine’s efficiency can suffer.
Replacing a faulty 04 Nissan Maxima camshaft position sensor is a relatively straightforward repair for many DIY enthusiasts, making choosing the right part even more important. Let’s look at the top contenders!

Factors to Consider When Choosing Your Sensor
When buying a 04 Nissan Maxima camshaft position sensor, here are a few things to keep in mind:
- Compatibility is King: Always, always double-check the part numbers and vehicle fitment. Even if your car is listed, cross-referencing OEM numbers can save you a headache. The 2004 Maxima uses the VQ35DE engine, and most compatible sensors will specify this.
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) parts are made by the same company that supplied Nissan. Aftermarket parts, like the ones reviewed here, are made by other manufacturers. Aftermarket options are usually more affordable and can offer comparable performance. Look for brands with good reviews and warranties.
- Warranty: A good warranty (12 months, 18 months, or even unlimited mileage) shows the manufacturer stands behind their product. This is a big plus for aftermarket components.
- Kit vs. Single Sensor: Decide if you need just one faulty sensor replaced, or if a full kit (both camshafts, or camshafts plus crankshaft) makes more sense for preventative maintenance or to address multiple related codes.
- User Reviews: While we’ve summarized general impressions, always take a quick look at recent customer reviews on Amazon. They can offer real-world insights into fitment, durability, and effectiveness.
Installation Tips (Briefly)
Replacing your 04 Nissan Maxima camshaft position sensor is often a DIY-friendly task. Here’s a quick rundown:
- Safety First: Disconnect your battery’s negative terminal.
- Locate the Sensor(s): Refer to your Maxima’s service manual. On the VQ35DE, they are typically on the back of the cylinder heads (Bank 1 and Bank 2) and the crankshaft sensor is usually near the transmission.
- Remove Old Sensor: Unplug the electrical connector, then unbolt the sensor.
- Install New Sensor: Ensure the new sensor’s O-ring is in place (or replace it if new one isn’t provided), then install it and re-bolt. Reconnect the electrical connector.
- Clear Codes: After reconnecting the battery, you’ll need an OBD-II scanner to clear any stored check engine light codes.
If you’re unsure or uncomfortable, don’t hesitate to consult a professional mechanic.
FAQ Section
What are the common symptoms of a bad 04 Nissan Maxima camshaft position sensor?
Typical symptoms include the illumination of the check engine light (often with codes like P0340 or P0345), hard starting, engine misfires or a rough idle, poor acceleration, and even unexpected stalling.
Where is the camshaft position sensor located on a 2004 Nissan Maxima?
Your 2004 Nissan Maxima (with the VQ35DE V6 engine) has two camshaft position sensors. Bank 1 (right side) is typically located on the passenger side cylinder head, and Bank 2 (left side) is on the driver’s side cylinder head, both towards the rear of the engine.
Can I replace the camshaft position sensor myself?
Yes, for many DIYers, replacing the camshaft position sensor on a 2004 Nissan Maxima is a relatively simple task. It usually involves disconnecting the electrical connector, removing a single bolt, pulling out the old sensor, and installing the new one. Always ensure the battery is disconnected before starting.
What’s the difference between Bank 1 and Bank 2 sensors?
In a V6 engine like the Maxima’s, “Bank 1” refers to the cylinder bank that contains cylinder #1 (typically the passenger side). “Bank 2” is the opposite bank (driver’s side). Each bank usually has its own camshaft, and thus, its own camshaft position sensor.
Do I need to replace the crankshaft position sensor too?
While not always necessary, it’s often a good idea to consider replacing the crankshaft position sensor along with the camshaft sensors. They work in conjunction to provide the ECU with precise engine timing data. If one is failing, the others might not be far behind, or symptoms can overlap. Many kits offer all three sensors together for convenience and value.
Will a faulty camshaft position sensor cause my 2004 Maxima to stall?
Yes, a failing or completely failed camshaft position sensor can absolutely cause your 2004 Nissan Maxima to stall. If the ECU doesn’t receive accurate or any data from the sensor, it can’t properly time the fuel injection and spark, leading to engine shutdown.
How long do camshaft position sensors typically last?
Camshaft position sensors don’t have a strict lifespan, but they can typically last well over 100,000 miles. However, like any electronic component exposed to engine heat and vibrations, they can fail prematurely.
Are aftermarket camshaft position sensors as good as OEM?
Many high-quality aftermarket camshaft position sensors are designed to meet or exceed OEM specifications, offering comparable performance and reliability at a lower cost. Look for products with good warranties and positive customer reviews to ensure you’re getting a reliable part.
Conclusion
A malfunctioning 04 Nissan Maxima camshaft position sensor can be a real headache, causing a range of frustrating engine problems. But thankfully, replacing it is often a straightforward fix, especially with the great aftermarket options available today. By choosing a high-quality replacement from our top picks, you can clear that annoying check engine light, restore your Maxima’s smooth performance, and get back to enjoying the drive with confidence. Happy wrenching!
