I recently got a CE light code and it threw me the code P0340 and it says camshaft position sensor A circuit bank 1 or single sensor. I have a 02 Subaru wrx impreza. I recently ordered a new sensor, but I would like to know what the problem could be. Also, I'm having a hard time identifying where the camshaft position sensor is at. Can someone please pinpoint the location for me? Any help will be appreciated. Thanks!
