Yes that is a code for an oxygen sensor that has low voltage. You probably need to replace it and you’ll be fine. The code is for Bank 2 Sensor 1, which is the first sensor on the right side of the engine.
Is there more than one on the right side? Where about is it located on the right side?
Yes there are two per bank. It would be one closest to the exhaust manifold on the right side of the engine. The other is after the catalytic converter.
Is it advisable to change both or just the one? If so where is the second located?
I would just change the one that is setting the code. No need to spend money on parts that are still good.
Just for clarity, when you say the right side of the engine, are you talking when you have the hood open and you are standing in front of the car, or when you are sitting in the car?
The right side of the engine is always the passenger side of the vehicle. Left is driver’s, right is passenger’s.
Live Chat: On your model year Firebird, there is ONLY an electric motor that raises and lowers the headlights. If you have one or both headlights not going up or down, you’d want to first check the drive motors for the headlamp doors to see if they are getting power. If so, you most likely have a bad motor mechanism. These aren’t too difficult to replace, but you do have to get your hand into some tight areas to do the work.
