p0505 and p1457 i changed out the throttle body yesterday and it had all the sensors on it but i got it used. these are the codes i got after i put it on i had 6 before i put it on
po505 is a fault in the idle control system more then likely a bad iac valve. also check for loose or unconnected vacuum tubes on the intake...
p1457 is an evap bypass solenoid failure...check for corrosion on the connector for it and if non is found then replace it and celar the codes out...the pic attached shows its location.
