Frequently Asked Questions about the 2004 Infiniti G35 Camshaft Position Sensor
Q1: What does a camshaft position sensor do in my 2004 Infiniti G35?
A1: The camshaft position sensor (CPS) monitors the rotational speed and position of the camshafts. This data is then sent to the engine’s computer (ECM/ECU), which uses it to precisely control ignition timing and fuel injection for optimal engine performance and fuel efficiency.
Q2: What are the common symptoms of a failing 2004 Infiniti G35 camshaft position sensor?
A2: Common symptoms include the illumination of the Check Engine Light (CEL), engine misfires, rough idling, difficulty starting (especially when warm), stalling, reduced fuel economy, and sometimes a sudden loss of power or hesitation during acceleration. You might also notice specific diagnostic trouble codes (DTCs) like P0340 (Camshaft Position Sensor Circuit Bank 1) or P0345 (Camshaft Position Sensor Circuit Bank 2).
Q3: How many camshaft position sensors does a 2004 Infiniti G35 have?
A3: Your 2004 Infiniti G35, equipped with the VQ35DE V6 engine, typically has two camshaft position sensors: one for Bank 1 (passenger side) and one for Bank 2 (driver side).
Q4: Can I replace the camshaft position sensor myself on my 2004 Infiniti G35?
A4: Yes, for many G35 owners, replacing the camshaft position sensor is a relatively straightforward DIY task. They are usually located on the cylinder heads and are held in by a single bolt. You’ll need basic tools, and it’s recommended to disconnect the battery before starting. There are many online tutorials and videos available to guide you.
Q5: Is it better to buy an OEM (Original Equipment Manufacturer) or aftermarket camshaft position sensor?
A5: OEM sensors are designed and built by the original manufacturer, often guaranteeing a precise fit and long-term reliability. Aftermarket sensors, while often more affordable, can vary in quality. Brands like Hitachi, which are OE suppliers, offer a good balance of quality and value. For crucial engine sensors, investing in a reputable brand is often recommended.
Q6: Will a bad camshaft position sensor damage my engine?
A6: While a failing camshaft position sensor won’t typically cause immediate catastrophic engine damage, it can lead to severe drivability issues. Prolonged driving with a faulty sensor can result in poor fuel economy, increased emissions, and put undue stress on other engine components due to incorrect timing, potentially leading to accelerated wear or other issues over time. It’s best to replace it promptly.
Q7: Should I replace my crankshaft position sensor if I’m replacing the camshaft position sensor?
A7: Not necessarily, but it’s often a good idea to consider it, especially if you’re experiencing intermittent issues or if your car has high mileage. The crankshaft and camshaft sensors work together for engine timing. Some diagnostic codes can point to either, and replacing both at once can ensure all critical timing sensors are fresh and working in harmony, saving you future diagnostic headaches.
