Hi.I got Check Engine Light a month ago, so I went to scan the code at Autozone. They show me the O2 sensors and knock sensor are malfunction.After that, I replaced all of the sensors but the CEL is still light on.I scaned again, they showed the same code which was already replaced by new sensors. What should I do next? or How to check the new sensors are working properly? Would you let me know how to get rid of the light?Thanks.

Try getting the ecu to "reset" itself

Wiring sub-harnesses are usually replaced also, expecially the KS ones.
