It is a sensor placed in the exhaust flow that indicates the level of unburned fuel in the exhaust so the computer can adjust the air- fuel ratio

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.

Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
It's integrated into the oxygen sensor. Buy a new oxygen sensor and you get a free oxygen sensor heater.
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.
