for 135 code you must do idle relearn after replacing part and erasing code in computer. also check fuse 11 and relay in picture under hood fuse box. for 498 code check resistance in valve if between 25-30 ohms on valve then there is a short between ecm and valve or wires. valve is under left hand floor.

DTC P0135 refers to a problem with the O2 (oxygen) sensor circuit.

DTC P0498 refers to a problem with the evaporative emissions (EVAP) system.

Did replace the A/F sensor with the original. Also did the idle relearn, the code did not return after driving, so I am checking on it.
Thanks
