O2 sensor 3 bank 4 where it is?

[Aleks]

I've done the OBD Torque check and shows me only 1 issue ,is :

 

MID:$0f TID:$dd

- O2 Bank 4 Sensor 3

Min: 4,184 Max: 16,224

Test result value: 20,488

FAIL

 

Does that means something or its just an error in the OBDll scanner (shows error coz sensor doesn't exist) ???????

 

P.S.: no error codes, no engine red lamp,etc.

 

Thanks!
