Frequently Asked Questions (FAQ)
Q1: What does a camshaft position sensor do in my Infiniti G37?
A camshaft position sensor (CPS) monitors the rotational speed and position of your engine’s camshafts. This information is crucial for the engine control unit (ECU) to precisely time fuel injection and ignition (spark plugs), ensuring your engine runs efficiently and powerfully. It essentially tells the ECU where the pistons are in their cycle.
Q2: What are the common symptoms of a bad G37 camshaft position sensor?
Symptoms of a failing camshaft position sensor in your Infiniti G37 can include:
* Illumination of the “Check Engine Light” (P0340, P0345, P0335, etc. codes).
* Rough idling or engine stumbling.
* Difficulty starting the engine, especially when warm.
* Reduced engine power or poor acceleration.
* Sudden stalling of the engine.
* Decreased fuel economy.
Q3: How many camshaft position sensors does a G37 have?
Your Infiniti G37, equipped with the VQ37VHR V6 engine, typically has two camshaft position sensors – one for each bank (cylinder head). There is also a separate crankshaft position sensor, which works in conjunction with the camshaft sensors for precise engine timing.
Q4: Is it difficult to replace the G37 camshaft position sensor myself?
For many G37 owners, replacing the camshaft position sensor is a moderately difficult DIY task. The sensors are usually located at the back of the cylinder heads, near the firewall. While accessible, it can be a bit cramped. You’ll need basic hand tools and potentially a flashlight. Always consult your car’s service manual or a reliable online guide before attempting the repair. If you’re uncomfortable, it’s best to consult a professional.
Q5: Can I drive with a bad camshaft position sensor?
While your G37 might still run with a failing camshaft position sensor, it’s generally not recommended to drive for an extended period. A faulty sensor can lead to unreliable engine performance, reduced fuel efficiency, potential stalling, and could even cause more serious damage to other engine components over time due to improper timing. It’s best to address the issue as soon as possible.
Q6: What’s the difference between a camshaft and crankshaft position sensor?
Both sensors are critical for engine timing, but they monitor different components. The camshaft position sensor monitors the camshaft’s position, which controls valve timing (when intake and exhaust valves open and close). The crankshaft position sensor monitors the crankshaft’s position, which relates directly to piston position and engine speed. Together, they provide the ECU with a complete picture of the engine’s rotational cycle, enabling precise fuel delivery and ignition.
Q7: Do I need to replace all camshaft sensors at once?
It’s often a good practice to replace both camshaft position sensors at the same time, especially if your G37 is getting older or has high mileage. If one sensor has failed, the other might not be far behind. Replacing them simultaneously can save you future diagnostic time and labor costs. Some kits, like the 23731-JA10B kit reviewed above, even include the crankshaft sensor for a comprehensive refresh.
Conclusion
A properly functioning camshaft position sensor G37 is essential for maintaining your Infiniti’s optimal performance and reliability. Don’t let a faulty sensor leave you stranded or compromise your driving experience. Whether you opt for the OE quality of Hitachi or Denso, the broad compatibility and warranty of A-Premium or HiSport, or the comprehensive solution of a multi-sensor kit, choosing a high-quality replacement is key.
By selecting one of these top 5 options, you’ll be well on your way to restoring your G37’s smooth idle, quick starts, and powerful acceleration. Drive confidently, knowing your engine’s timing is precisely controlled.
