P1684 The battery has been disconnected within the last 50 starts.
P0340
This indicates that a problem was detected in the camshaft position sensor
circuit. Since it says circuit, that means the problem could

Don't just replace the CPS (camshaft position sensor) and think that will definitely
fix it.
