Did you buy the universal replacement sensor where you use the plug off of the old sensor and the splice kit? If so, that is most likely the issue. Had the same problem on a 2003 Avalon. Bought the ones with the plug and codes cleared. ps. Check Amazon.com, lots less expensive.

Make sure the check engine light was cleared after you replaced the o2 sensor....if the codes were not cleared then it will come on forever even if thetre is no problem

The upper sensors are air fuel sensors and the lower ones are o2 sensors. you cant mix these up. Assuming you did everything right and still coding then either the new sensor b1s2 is bad or the wirng(power and ground need to be checked. A scan tool can be used to look at the performance of the sensors too. Sometimes the codes just point to the area of the problem and changing the part isn't the answer.

Crank/cam misaligned timing can be due to a slack timing belt jumping a tooth on a cog. Check that the belt is tight and that the timing marks on belt align with the cam and crank pulley timing marks.
