My 2006 Infiniti G35 Sedan has served me quite well for a number of years, and despite it’s high mileage, been an excellent car for most of it’s life.
With over 200k on the odometer, I guess I cannot fault the Infiniti for acting up recently but I’ve had a difficult time diagnosing it’s current issue. It doesn’t happen all the time, but when warm, the car begins to sputter and misfire and occasionally lurches off idle or with slight acceleration.
After which time, the check engine light never seemed to light off, but the VCD and ABS lights would stay lit after the car would sputter. After wrongly assuming it was coil related I started testing them, until the car finally threw a code so that I could diagnose it.
And lo and behold, it’s the good ol P0345 OBDII error – P0345 Camshaft Position Sensor Failure A Circuit Bank 2 ; this code indicates that a problem was detected in the camshaft position sensor circuit of bank 2 ( which is the driver side of your VQ35DE).
The steps to diagnose your P0345 code in your G35 ( or any car for that matter )
