i have replace oxygen sensor on my 2005 nissan maxima but the service engine light stil on. it keeps telling me giving me same code

that code you read does not tell you to replace an 02 sensor or any part,it is a generic code and is only one of the possible causes and a starting point! drive cycle is not needed if the CEL(SES) light is still on,the readiness monitor will never set to ready or pass emissions testing as long as that light is on. Professional Scan Test needed,instead of guessing and throwing parts/money at it.
