Question about 1996 Chevrolet Camaro
Keeps hitting codes for ho2 sensor circ. malf. after i changed o2 sensor
Have you upgraded the exhaust if you did you sometimes have to set the computer for the new exhaust if not it will set off codes until you do

Are there any other codes set?. frist i would look at the map sensor readings. the map sensor reads vauccmn at ilde the engine shows a high vacuumn reading 14 to 21 inches, as the throttle is opended up vacuumn drops, if the sensor dose not responds the pcm will go to a fixed value. which means the o2 sensor will only read what it senses in the exhaust, what you have to remeber is that the o2 sensors are the last sensors to see what and how the mtr is running. if you do not have abilty to look at the data stream you may end up spending more money by replacing parts until you fix it . good luck and let us know what happens

This fault code refer at Oxygen O2 Sensor Circuit Low Voltage (Bank 2, Sensor 2), and basically means the PCM detected either an excessive current draw, or an open or short in the circuit powering the oxygen sensor's heater circuit. This is in reference to the Heated Oxygen Sensor (2) located rear of catalytic converter (Bank 2).
A code P0161 may mean that one or more of the following has happened:
