Hello, P0341 deals with the camshaft being out of sync with the crankshaft, this can be caused by several things, a faulty VTEC oil control solenoid, a faulty cam phaser, or a stretched timing chain. What you would need to do is inspect each component for proper operation, if you're not able, the most common thing I've seen in a faulty oil control solenoid.
If you have any other questions please let me know. If you're happy with the information I've provided please click accept.
Ok, the solenoid is located on the passenger side of the engine, as show in the image below.
It's held in with a single bolt, it's not too difficult to change.
