02 code

[dennyo]

recently got a code for 02 sensor on bank 2 (right side) and decided to get it changed and at the same time had the separator cover changed.The problem i am having now is the code keeps returning even though the dealer said they erased it and i have tried many times to erase it with my scanner.Anyone have this happen before? What i get is po145 and po145 pd(pending).Any help is greatly appreciated. dennis
