Unheated or heated oxygen sensors

Unheated or heated oxygen sensors
I received 4 O2 sensors but they were unheated. In the repair manual, it only talks about heated sensors. When I ordered the sensors, it did not say anything about unheated. Does it matter if they are unheated? I have already replaced the plugs and wires. Here in Oregon, by law, the parts store cannot clear codes. The first time I hooked up the OBDII reader, it gave a code of PO135 and PO134. Any help would be greatly appreciated.
