That is a proprietary code and is different in some vehicles but on GM/ Dodge vehicles it would be P1547 A/C System Performance Degraded ... For VW it is P1547, Wastegate Bypass Regulator Valve Short To Ground For Subaru it is P1547, Exhaust Gas Temperature Sensor Malfunction .. For Audi it is P1547 Boost Pressure Control Valve Short To Ground

There are many different signs that will tell you that your Honda P1457 will need to be checked. Some of the more common are when the engine knocks and you start losing power.

Generic code P1457. EVAP Control system leakage.

No, it will not harm the engine. P1457 will not harm the engine nor will it make the engine run bad. It just means the EVAP canister & the related system of hoses & valves is not airtight as it should be. You have a leak somewhere.

The code specifically means P1457 Evaporative Emissions (EVAP) Control System Leakage (EVAP Canister System). These can be very tricky to find. First thing and cheapest thing to do is replace the gas cap and then see if the check engine light goes out after your drive it enough or have the light reset. If that does not work then you need to take it to a shop and have a smoke test run.
