I own a 2001 Pathfinder SE 4x4, auto. with a touch over 41000 miles. My SES light came on a few days ago, so a trip to Auto Zone revealed a P0340 code, which through my research I have learned this is for "Camshaft Position Sensor A - Bank 1 Circuit malfunction". This is great that I now know this, but when researching this part, there are 2 of them, front and rear. I ask if any of you happen to know any way of diagnosing which one is bad, I would be very greatful for any help received. :banghead:
