Still shows faulty code
About a week after replacing this unit the check engine light came back on. Had it checked and again it was saying o2 sensor malfunction. I removed it and reinstalled it and worked for a couple days then the check engine light came on again. I hate to spend the money but looks like im going to have to buy a Honda O2 sensor.......
