10 Best 2005 Infiniti G35 Camshaft Position Sensor Replacements for Peak Performance
Hey, G35 owners! If you’re driving a 2005 Infiniti G35, you already know it’s a fantastic blend of luxury and performance. But like any car, it needs its key components to be in tip-top shape. One of those unsung heroes under the hood is the camshaft position sensor. This tiny but mighty part plays a crucial role in your engine’s smooth operation, making sure everything fires just right.
When your 2005 Infiniti G35 camshaft position sensor starts acting up, you might notice your G35 feeling a bit sluggish, hard to start, or even throwing that dreaded “Check Engine” light. Don’t sweat it, though! Replacing this sensor is a common fix, and there are plenty of reliable options out there. We’ve scoured the market to bring you a list of the 10 best 2005 Infiniti G35 camshaft position sensor replacements to help you get your ride back to its prime.
Why Your Camshaft Position Sensor Matters So Much
Before we dive into the best picks, let’s quickly chat about why this sensor is so important. Essentially, the camshaft position sensor (CPS) tells your car’s engine control unit (ECU) exactly where the camshafts are in their rotation. This information is vital for the ECU to precisely time fuel injection and ignition spark. Without accurate data from the CPS, your engine can’t run efficiently.
Symptoms of a failing sensor often include:
* Check Engine Light (CEL): This is usually the first sign, often with specific trouble codes like P0340 or P0345.
* Hard Starting or No-Start: The engine struggles to crank or won’t start at all.
* Engine Stalling: Especially at idle or low speeds.
* Rough Idle or Misfires: The engine feels shaky or performs inconsistently.
* Reduced Fuel Economy: Your gas mileage might take a hit.
* Decreased Engine Performance: Noticeable loss of power or acceleration.
If you’re experiencing any of these issues, a faulty camshaft position sensor could very well be the culprit.

Frequently Asked Questions (FAQs)
What does a camshaft position sensor do in a 2005 Infiniti G35?
The camshaft position sensor (CPS) monitors the rotational speed and position of the camshaft. This information is sent to the engine’s computer (ECU), which then uses it to accurately time the fuel injection and ignition spark, ensuring the engine runs smoothly and efficiently. Your 2005 Infiniti G35 has two camshaft position sensors, one for each cylinder bank.
How do I know if my 2005 Infiniti G35 camshaft position sensor is bad?
Common symptoms of a failing 2005 Infiniti G35 camshaft position sensor include the “Check Engine” light illuminating (often with codes like P0340, P0345, P0335), difficulty starting the engine (especially when warm), engine stalling, rough idling, misfires, reduced power, or decreased fuel economy.
Can I replace the camshaft position sensor myself on my 2005 G35?
Yes, replacing the camshaft position sensor on a 2005 Infiniti G35 is a fairly common DIY task. The sensors are usually located on the valve covers at the rear of the engine (for the VQ35DE). You’ll typically need basic hand tools. However, always consult your service manual for exact location and procedure, and ensure the engine is cool before working on it.
Are aftermarket camshaft position sensors reliable?
Many aftermarket camshaft position sensors are very reliable and offer excellent value compared to OEM parts. Brands like Hitachi, which is an OE supplier, offer top-tier aftermarket options. Other reputable brands also produce quality sensors that meet or exceed original specifications. Always check reviews and warranties to ensure you’re getting a good product.
How many camshaft position sensors does a 2005 Infiniti G35 have?
The 2005 Infiniti G35, equipped with the VQ35DE V6 engine, has two camshaft position sensors. These are often referred to as Bank 1 (right side) and Bank 2 (left side) sensors. It also has one crankshaft position sensor, which works in conjunction with the cam sensors for precise engine timing.
What’s the difference between a camshaft and crankshaft position sensor?
Both are crucial for engine timing. The camshaft position sensor (CPS) monitors the camshaft’s position, which controls valve opening and closing. The crankshaft position sensor (CKP) monitors the crankshaft’s position, which determines piston location and engine RPM. The ECU uses data from both to accurately time fuel injection and ignition for optimal performance.
How long do camshaft position sensors typically last?
Camshaft position sensors don’t have a fixed lifespan; they can last anywhere from 80,000 to 150,000 miles or more. Their lifespan can be affected by heat, vibrations, and general wear and tear. If one fails, it’s often a good idea to consider replacing both cam sensors (and potentially the crankshaft sensor) due to their similar age and exposure to the same conditions.
Keep Your G35 Humming!
Replacing a faulty 2005 Infiniti G35 camshaft position sensor doesn’t have to be a headache. With the right part, you can quickly restore your G35’s performance and enjoy its legendary drive once again. Whether you opt for an OEM-grade part or a reliable aftermarket alternative, the key is choosing a sensor that offers accurate readings and a dependable lifespan. Happy driving!
