Understanding Your Infiniti G35 Camshaft Position Sensor: FAQs
Q1: What does an Infiniti G35 camshaft position sensor do?
A: The camshaft position sensor (CPS) measures the rotational speed and position of the camshaft. This data is sent to the Engine Control Unit (ECU), which uses it to precisely control valve timing, fuel injection, and ignition timing, ensuring your engine runs efficiently and powerfully.
Q2: What are the symptoms of a bad Infiniti G35 camshaft position sensor?
A: Common symptoms include:
* Illuminated “Check Engine Light” (CEL) with codes like P0340, P0345, P0335.
* Hard starting or prolonged cranking.
* Rough idling or engine stalling.
* Decreased fuel economy.
* Reduced engine power or poor acceleration.
* Engine misfires.
Q3: Can I replace the Infiniti G35 camshaft position sensor myself?
A: Yes, for many G35 owners, replacing the camshaft position sensor is a straightforward DIY task. They are usually located on the valve covers (Bank 1 and Bank 2) and are held in by a single bolt. Access can be a bit tight, but with basic tools and a good tutorial, it’s definitely doable.
Q4: How many camshaft position sensors does an Infiniti G35 have?
A: Your Infiniti G35 (with the VQ35DE engine) typically has two camshaft position sensors: one for Bank 1 (passenger side) and one for Bank 2 (driver side). Some models may also have a crankshaft position sensor, which often fails around the same time and is part of the same system.
Q5: Is there a difference between Bank 1 and Bank 2 sensors?
A: Yes, for the Infiniti G35, the Bank 1 (right/passenger side) and Bank 2 (left/driver side) camshaft position sensors are typically different parts. They have distinct OEM part numbers and shapes to fit their respective locations. Make sure you get the correct one for the bank that’s faulty, or replace both if advised.
Q6: How long do camshaft position sensors last?
A: The lifespan of a camshaft position sensor can vary, but they generally last many years or over 100,000 miles. However, exposure to extreme temperatures, vibrations, and electrical issues can cause them to fail prematurely.
Q7: What causes a camshaft position sensor to fail?
A: Most failures are due to normal wear and tear, exposure to heat, and internal electrical component breakdown. Issues with wiring harnesses, sensor contamination (e.g., oil sludge), or physical damage can also lead to failure.
Q8: Will a bad camshaft position sensor damage my engine?
A: While a failing camshaft position sensor won’t typically cause catastrophic engine damage directly, it can lead to various engine performance issues. Driving with a faulty sensor can result in poor fuel economy, increased emissions, and a less reliable vehicle, potentially causing issues with other components over time due to improper engine timing. It’s best to replace it promptly.
Final Thoughts
Dealing with a faulty Infiniti G35 camshaft position sensor can be frustrating, but replacing it is a common and often simple fix that can bring your car’s performance right back to spec. Whether you opt for a single sensor, a pair, or a comprehensive kit that includes the crankshaft sensor, you’ve got excellent options available. Always double-check compatibility with your specific G35 model year, and don’t hesitate to consult a professional if you’re unsure. Happy driving!
