Frequently Asked Questions (FAQ)
Q1: What does a camshaft position sensor do in my 2004 G35?
A: The camshaft position sensor monitors the rotational speed and position of your engine’s camshaft. This data is crucial for the engine control unit (ECU) to precisely time fuel injection, ignition, and variable valve timing (VVT) on your VQ35DE engine, ensuring efficient combustion and optimal performance.
Q2: What are the common symptoms of a failing 2004 G35 camshaft position sensor?
A: Common symptoms include the “Check Engine” light illuminating (often with codes like P0340 or P0345), difficulty starting (especially when the engine is warm), rough idling, misfires, reduced engine power, poor fuel economy, and sometimes the engine stalling.
Q3: Can I drive my 2004 G35 with a bad camshaft position sensor?
A: While your G35 might still run, it’s not recommended to drive with a faulty camshaft position sensor for long. It can lead to unpredictable engine behavior, reduced performance, poor fuel efficiency, and potentially cause damage to other engine components due to incorrect timing or misfires. It’s best to replace it as soon as possible.
Q4: How difficult is it to replace a 2004 G35 camshaft position sensor myself?
A: For most DIYers with basic mechanical skills, replacing a camshaft position sensor on a 2004 G35 is a moderately easy job. The sensors are typically located on the valve covers or near the crankshaft. You’ll usually need a few basic tools (sockets, wrenches) and about 30-60 minutes per sensor. Always disconnect your battery before starting!
Q5: Are the camshaft and crankshaft position sensors the same?
A: No, while both are essential for engine timing, they are distinct sensors. The camshaft position sensor monitors the camshaft’s rotation, while the crankshaft position sensor tracks the crankshaft’s rotation. The ECU uses data from both to determine the exact position of the engine’s pistons and valves, ensuring precise fuel and spark delivery.
Q6: Why does my G35 have two camshaft position sensors?
A: The VQ35DE engine in your 2004 G35 is a V6 with two cylinder banks (Bank 1 and Bank 2). Each bank has its own camshaft, and thus, its own camshaft position sensor to monitor the timing of that specific camshaft, especially with variable valve timing systems.
Q7: Which engine codes are commonly associated with a bad camshaft position sensor on a 2004 G35?
A: The most common diagnostic trouble codes (DTCs) related to a faulty camshaft position sensor are P0340 (Camshaft Position Sensor Circuit Malfunction – Bank 1) and P0345 (Camshaft Position Sensor Circuit Malfunction – Bank 2). Other related codes might include P0341, P0346, or misfire codes like P0300.
Final Thoughts
Finding the right 2004 G35 camshaft position sensor is key to keeping your beloved Infiniti running smoothly. Whether you opt for a high-quality OEM-grade part like Hitachi or a comprehensive aftermarket kit that covers all your timing sensor needs, the goal is always to restore proper engine function. Don’t let a failing sensor leave you stranded or cause further engine troubles. Choose wisely from our top picks, and get your G35 purring like it should be!
