Having some issues with my 04 350z. Its throwing code P0345 with my slip & traction control light on aswell. The code indicates a fault in the bank 2 camshaft sensor A. Ive replaced the sensor & the car is still acting the same. I went ahead & replaced the other cam sensor & crankshaft sensor as well & no luck. The car cranks for 4-5 seconds but turns on. All of these issues started the day after I got a car audio system installed professionally. My car had no problems before the install. Ive looked up similar threads on here & other forums. No luck. Hoping someone has any ideas/solutions.
