Fix Your G35’s Engine: 10 Top 03 Infiniti G35 Camshaft Position Sensors Reviewed
Ever had your beloved 03 Infiniti G35 act a little… finicky? Maybe it’s struggling to start, idling rough, or even stalling out on you? These frustrating symptoms often point to a crucial component under the hood: the camshaft position sensor. This unsung hero plays a vital role in your VQ35DE engine’s performance, telling the car’s computer (ECU) exactly where the camshafts are, which is essential for precise ignition timing and fuel injection. When this sensor goes bad, your G35 can really lose its pep.
Don’t sweat it, though! Replacing a faulty 03 Infiniti G35 camshaft position sensor is a common fix, and it’s definitely something you can tackle. But with so many options out there, how do you pick the right one? That’s where we come in. We’ve dug deep to review 10 top-rated camshaft position sensors compatible with your 2003 Infiniti G35, helping you get your ride running smoothly again.
Why Your 03 Infiniti G35 Might Need a New Camshaft Position Sensor
Think of the camshaft position sensor (CPS) as the brain’s timing expert. It sends signals to your engine’s control unit, ensuring the engine knows exactly when to fire the spark plugs and inject fuel. If this sensor malfunctions, it can throw off the entire timing, leading to a host of nasty issues. You might notice:
- A check engine light illuminated on your dash, often accompanied by codes like P0340 or P0345.
- Hard starting or long crank times.
- Rough idle or stalling.
- Reduced engine power and acceleration.
- Poor fuel economy.
- Engine misfires.
If any of these sound familiar, it’s probably time to consider a replacement. Getting a high-quality 03 Infiniti G35 camshaft position sensor is key to restoring your car’s optimal engine performance and reliability.
Understanding Camshaft Position Sensors for Your G35
Your G35’s 3.5L V6 engine typically uses two camshaft position sensors: one for Bank 1 (passenger side) and one for Bank 2 (driver’s side). Some kits even include a crankshaft position sensor, as they often fail around the same time and work in conjunction to provide engine timing data. Always double-check compatibility with your specific year and model.

Buying Guide: What to Look For in a Camshaft Position Sensor for Your 03 Infiniti G35
When you’re ready to buy a new 03 Infiniti G35 camshaft position sensor, keep these points in mind:
- Compatibility is Key: Always, always double-check the product’s fitment list. Ensure your specific year (2003) and engine (3.5L V6) are explicitly mentioned. OEM part numbers are your best friend for cross-referencing.
- Single vs. Kit: Do you need one sensor, both camshaft sensors, or even the crankshaft sensor too? Diagnostic codes (like P0340, P0345) can help pinpoint the exact faulty sensor. Often, replacing them in pairs or as a set is a good preventative measure.
- OEM vs. Aftermarket: While OEM parts are a guaranteed fit, high-quality aftermarket sensors can offer comparable performance at a better price. Look for brands with good reputations and strong warranties.
- Warranty: A good warranty (12 months, 18 months, or even a lifetime) is a strong indicator of a manufacturer’s confidence in their product.
- User Reviews: Don’t just take our word for it! Read what other G35 owners have to say about specific sensors. Look for comments on fitment, ease of installation, and how well the product resolved their issues.

FAQ Section
Q1: What are the common symptoms of a bad camshaft position sensor in an 03 Infiniti G35?
A1: Common symptoms include the check engine light (often with codes like P0340 or P0345), hard starting, rough idling, engine stalling, reduced engine power, poor acceleration, and decreased fuel economy.
Q2: How many camshaft position sensors does an 03 Infiniti G35 have?
A2: The 03 Infiniti G35, with its VQ35DE V6 engine, typically has two camshaft position sensors: one for Bank 1 (passenger side) and one for Bank 2 (driver’s side). Some kits may also include the crankshaft position sensor.
Q3: Is it difficult to replace the camshaft position sensor on a 2003 Infiniti G35?
A3: For a mechanically inclined individual, it’s often considered a moderately easy DIY job. The sensors are located on the back of the engine. However, space can be tight, so patience and the right tools are key. If you’re not comfortable, professional installation is recommended.
Q4: What’s the difference between Bank 1 and Bank 2 camshaft sensors?
A4: Bank 1 refers to the cylinder bank that contains cylinder #1 (passenger side on a VQ35DE), while Bank 2 refers to the opposite bank (driver’s side). The sensors are often slightly different in design or connector angle to fit their specific locations.
Q5: Can a faulty camshaft position sensor cause my G35 to stall?
A5: Yes, absolutely. A malfunctioning camshaft position sensor sends incorrect or no signals to the engine control unit (ECU), which then struggles to properly time ignition and fuel delivery, leading to engine stalling, especially at low speeds or when coming to a stop.
Q6: Do I need to replace the crankshaft position sensor if I replace the camshaft position sensors?
A6: Not always, but it’s often recommended, especially if you’re experiencing multiple timing-related issues or if your car has high mileage. The crankshaft and camshaft sensors work together for engine timing, and they often wear out around the same time. Many aftermarket kits offer all three sensors as a bundle.
Q7: Will replacing the camshaft position sensor clear the check engine light automatically?
A7: Sometimes, the check engine light will clear itself after a few driving cycles once the new sensor is installed and the ECU receives correct signals. However, it’s often best practice to clear the diagnostic trouble codes (DTCs) manually using an OBD-II scanner after replacing the sensor to ensure the system fully resets.
