Question about 2002 Toyota Avalon
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.
