"Post-cat" refers to an oxygen sensor located after the catalytic converter, while "pre-cat" refers to an oxygen sensor located before the catalytic converter. The post-cat sensor monitors the efficiency of the catalytic converter, while the pre-cat sensor helps regulate the air-fuel mixture before it reaches the converter.
An oxygenated water (with a higher concentration of oxygen).
Oxygen
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
not quite sheer but it is not your momma and it has something to do with nitrogen and oxygen
Anaerobic means without oxygen.
oxygen sensor
There is a failure in the oxygen sensor heater.
Right upstream oxygen sensor heater failure.Right upstream oxygen sensor heater failure.
This tells you which oxygen sensor is out, look at your vehicle diagram to see where this sensor is located.
Oxygen sensors do no work well when they are cold so manufactures have installed a heater in the sensor to get it up to speed quickly.
Bank 2 sensor 2 refers to the oxygen sensor on the passenger side of the exhaust system and after the catalytic converter. heater circuit is the oxygen sensor or the wiring going to it, it is what is called a heated oxygen sensor. Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
Never heard of an "ignition sensor". Do you mean oxygen sensor, or maybe crank position sensor, or cam position sensor? There is an ignition "module" also... The oxygen sensor is on the exhaust manifold. The crank posiiton sensor is on the backside of the block. The cam position is on each head.
A system malfunction in the Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) heater circuit.The cause can be a loose wire or a defective Primary Oxygen Sensor
Bank 1 sensor 1 is the first oxygen sensor usually in the exhaust manifold. Usually it needs to be replaced. Sometimes it can just be a bad connection in the plug for the oxygen sensor.

Gas sensor? Not sure what you mean, could it be a Fuel gauge sensor? Oxygen sensor? Fuel pressure regulator?
