my brother car is a 96 honda civic hatchback. it has a B16A2 bar'd into the car. it is OBD2 with a PP2 ECU. just recently threw an engine code P1457. i need your help to fix this engine code. any tips is appreciated. thank you.

P1457 Evaporative Emission Control System Leak Detected (Control Canister System)

 

take it to the dealer. they can run a evap test that can help narrow the down the suspects. i have seen lots of bad solenoids and canister. i have also seen a lot of people not have there gas cap tight or not on at all but that would cause P1456 (tank side). the two codes get mixed a lot. what car is the PP2 ecu from?
