Frequently Asked Questions (FAQ)
Q1: What are the common symptoms of a bad G37 camshaft position sensor?
A: Common symptoms include the illumination of the “Check Engine Light” (CEL), rough idling, engine stalling (especially when coming to a stop), difficulty starting the engine, decreased fuel efficiency, uneven acceleration, and potential engine misfires or vibrations. You might also notice your G37 entering “limp mode.”
Q2: Where is the camshaft position sensor located on a G37?
A: The Infiniti G37 (with the VQ37VHR engine) typically has two camshaft position sensors, one for each bank of cylinders. They are usually located on the back of each cylinder head, often near the firewall. You might also have an intake and exhaust camshaft sensor for each bank. A quick search for “G37 camshaft position sensor location” will yield diagrams specific to your year.
Q3: Can I replace a G37 camshaft position sensor myself?
A: Yes, for many DIY enthusiasts, replacing a g37 camshaft position sensor is a manageable task. It typically involves disconnecting the electrical connector, unbolting the old sensor, and installing the new one. However, access can sometimes be tight, requiring specific tools. Always consult your vehicle’s service manual or a reliable online guide before attempting the repair.
Q4: Will a faulty camshaft position sensor prevent my G37 from starting?
A: A failing or completely failed camshaft position sensor can absolutely prevent your G37 from starting. The engine control unit (ECU) relies on this sensor’s input to determine engine timing and fire the spark plugs and fuel injectors correctly. Without this critical data, the ECU might not allow the engine to crank or start.
Q5: What diagnostic trouble codes (DTCs) are associated with a bad camshaft position sensor?
A: If your g37 camshaft position sensor is faulty, you’ll likely encounter specific OBD-II diagnostic trouble codes. Common codes include P0340 (Camshaft Position Sensor Circuit Malfunction – Bank 1 or Single Sensor), P0345 (Camshaft Position Sensor Circuit Malfunction – Bank 2), P0341, P0346, etc. Using an OBD-II scanner can confirm these codes.
Q6: Is it better to replace both camshaft position sensors at once?
A: While not always strictly necessary, it’s often recommended to replace both camshaft position sensors (if your G37 has two) at the same time, especially if they are original and of similar age. If one has failed, the other might not be far behind. Many kits, as reviewed above, offer multiple sensors for convenience and cost savings.
Q7: How long do G37 camshaft position sensors typically last?
A: The lifespan of a camshaft position sensor can vary widely, but they generally last for a good portion of a vehicle’s life, often 100,000 miles or more. However, they are electronic components exposed to heat and vibration, so early failure is not uncommon. Regular engine maintenance can indirectly help prolong their life.
Final Thoughts
A properly functioning g37 camshaft position sensor is vital for your vehicle’s engine health and overall performance. Whether you opt for a trusted OE supplier like Hitachi or Denso, or a reliable aftermarket brand like A-Premium or HiSport, choosing a quality replacement will help restore your G37’s smooth idle, powerful acceleration, and clear your dashboard of that annoying check engine light. Always remember to verify fitment for your specific G37 model year and engine to ensure a perfect match. Happy driving!
