SOURCE: a p0340 trouble code and i changed the cam

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.
