The Fix
Best first action is a tune up, new plugs, wires, inspect all hoses and wire connections then reset the code. If it returns you will need to narrow it down to a system, coils and coil packs should be tested, catalytic converters for function ( do you smell rotten eggs?). A misfire that jumps cylinders could indicate a lean condition, do you have any other codes along with the 300? this will help clue you in to the source, check valve function to make sure they are opening and closing fully.
This is probably pone of the most difficult codes to troubleshoot, so start with the basics and work your way into the more expensive options, in many cases a good old tune up solves the problem, back it up with a fuel system cleaning and see where you stand.
that you have a fault with your engine, and need to get it to a garage to be checked out
either you need a service or their is a fault with the engine system, either way take it along to a garage.
It can only be turned off with Consult II/III, Nissans diagnostic computers. However some none manufacturer specific CAN erase fault codes. either way, you need a code reader.
You can reset it but if the fault is not rectified then it will just keep coming back on.. Almeras have a glitch on there em lights caused by any little fluctuation.. There are not a plug in buld but soldered onto the circuit board, break the connection, light out....
