my check engine codes, need help
Secondary H0S12 (heated oxygen sensor - bank 1 sensor 2) circuit low voltage
Probable cause
Poor electrical connection
Air leak near H02S (bank 1 sensor 2)
Lean A/F ratio
Faulty H02S12 (bank 1 sensor 2)
Please explain in detail and what do i have to do to fix this problem?

Re: my check engine codes, need help
There is an issue with your SHO2S, aka Secondary Heated Oxygen Sensor. It is located under the car next to the catalytic converter.
Check the electrical connection to the secondary O2 sensor. Make sure it is clean and tight.
If you have an exhaust leak in front of your secondary O2 sensor, fix the leak.
If you just recently replaced your catalytic converter with a cheap high flow or test pipe... this is a normal code and there is really not much you can do besides try and hack the signal or use a spark plug defouler.
