P0456 = EVAP Emissions Control System Leak Very Small

Is the gas cap on tight or is the seal damaged? If it needs replacement, get it from the dealer.

The camshaft position sensor is located on the engine near the timing belt cover and under the upper radiator hose.

weeeeiiirrdddd. i have a 2001 hyundia elentra gls, and my third cylinder is misfiring as well. my car also revs constantly on idle and in between shifting. it will flutter between 2-3000 or it will just stay at 5000. i replaced my plugs and wires to no fix with my cylinder. autozone also told me that it sounds like my throttle position sensor needs replaced, but every part they try to sell me will not fit and they swear up and down this is the right part...

Most of the time they mean:
p0441 = Evaporative Emission System Incorrect Purge Flow
p0422 = Evaporative Emission Control System Leak Detected (small leak)
