May Check engine light is on and we hooked up the computer to tell us whats wrong. There are 4 02 sensors in the car there is 02s11,21,12,22 but i am not sure which one is 02s21 cause thats the one not showing voltage. There are two in front of the engine and two behind it do you have any idea where the 02s21 is ?

Bank 2 sensor 1 is the one before cat (on the exhaust manifold) in the front closer to the radiator. If the scan showed no voltage, check for possible wiring damage before you replace the sensor.
