Hi siki951972,

P1456 = EVAP Cntrol System Leakage ( fuel Tank System) It could be the solenoid or other components and testings have to be done to locate the source.

P0845 = 3rd clutch pressure switch circuit.

P0420 = Catalyst System Efficiency Below Threshold. Usually it is the catalytic converter that is faulty, unless there is a leakage in the exhaust system.
