if sensor indicates lean check the fuel trim if long term fuel trim is above +7 them test sensor with a piko lab scope or watch scan data and create a rich condtion by snping the throttle wide open and watch the sensor if it start to read around 700to 900mv its ok, then create a vacume leak and the sensor should read 100to 300mv i your sensor is in this range quickly its good with in 1to2 sec.

Code P0340 is a camshaft position sensor CIRCUIT fault. This means it can be a bad sensor, wiring fault (loose connector, short, open), or even a bad PCM. Since you've already changed the camshaft position sensor you've eliminated that possibility. It's time to do some electrical troubleshooting. That, of course, depends upon your skill set for this type of work and equipment (mostly a good dmm and schematics). If you're not equipped for this then you'll likely have to seek assistance from a local shop.
