I'm getting code that both o2 sensors have low signal heating element or signal. don't have it in front of me. Unlikely they both went at same time but with over 100k not a bad maintenance item anyway. Replaced them and still get code for both.
I saw something about the computer but can't find it again.

Is your car Nissan? The on-board computer detector needs to be driven and heated. The water temperature reaches 80 degrees. The voltage value of the o2 sensor of the computer detector will continuously change from 0v-1v. The faster the frequency, the better the sensor. For reference only....
