As it says.... I had a new check engine light deliver me a P0157 engine code. Bank 2 Sensor 2 low voltage. Monitored the voltage for a while, upon start up it reads equal to the Bank 1 Sensor 2 voltage around 0.7-0.8 volts at idle, then it drops down to 0.035 volts. Very strange though because I drove around monitoring the sensor, and when I accelerate hard enough, it comes back to life and reads equal to Bank 1 Sensor 2 again.

Do you think this sensor is clogged or is the connection pooched? If I sit at idle and rev it up it does not match the other rear sensor.... this makes me think its a bad connection, and the vehicle movement may be making the connection better when I accelerate hard, causing the sensor to read ok.

I have headers and no cats for the record. Everything has been fine since the install until now, I might re-diagnose later as well...

I think you have to get new sensor as it may have been damaged. Are those the stock sensors you transferred to the aftermarket headers? I had to replace mine when i had my headers installed as the oem sensor got stripped when removing it from the oem headers.
