1999 Honda Odyssey LX with engine code P1457

Question

Scanned and diagnosed the computer and the P1457 code came out. The mechanic had already changed the EVAP canister to a new one and after driving 50 miles, the check engine light came out again. The vehicle was scanned again and the check engine shows the same code.

Answer 1

HI there,

This code basically means there is a leak in the system. Sometimes the only way to locate the leak is with a smoke test.
