Order of inspection
P0343 Camshaft Position Sensor A Circuit High (Bank 1) Medium
The P0343 code means the signal from the bank 1 camshaft position sensor A is higher than the computer expects. Without a good camshaft signal the computer cannot tell which stroke each cylinder is on, so the engine can be hard to start, hesitate or stall. An open signal circuit or a broken sensor ground is the usual reason.
