How to clean O2 sensor on a 2007 Pontiac G6?

The fuel composition sensor goes by several other names: flex fuel sensor, fuel compensation sensor, and variable fuel sensor. Its exact location varies according to the vehicle's make and model, but you can usually find it in the fuel line that connects the fuel tank and the injectors
This for flex fuel models not sure Pontiac had it.

Hi. Generic code description is
O2 sensor 1 bank 2 Heater control circuit.
Means the heated oxygen sensors internal heating element isn't working. Visual inspection of wiring and plug then if that's ok and you haven't any live data its probably worth a shot at replacing the O2 sensor itself. You can check the resistance of the heater element with a multi meter on ohms by disconnecting the O2 sensor plug and compare it to the other sensors for a guide if your technically minded. Jon.

It is located on top of the fuel sending unit on the fuel tank. The tank needs to be dropped in order to service the pressure sensor. It's not real common for them to go bad and there are several other possibilities that can make this code appear. It may be worth checking them out also. It would be nice if you could oust the actual code you are getting also.

2007 G6 pontiac brake pedal position sensor location?

On left end of rear cylinder head

Bank 1 doesnt matter on a four cylinder engine. In 6 or 8 cylinder engines they use Bank 1 or Bank 2 to clarify what side of the engine they are talking about. On yours there are 2 Oxygen sensors (O2) replace them both for best performance.

Bank 1 is always the cylinder bank that has piston/cylinder no. 1 in it; usually the left side in a rear wheel drive GM, or the front side in a front wheel drive GM. The O2 sensor will be located on either the exhaust manifold, engine exhaust pipe after the exhaust flange, or on the catalytic converter for the 2 bank.
