On the end of the sensor there is a resistor. When a resistor is use in the manner, it is being use to measure temperature. In this case, the temp. of the exhaust. Most of the time the sensor is just dirty, with carbon. This can make it read either way, too hot or too cold. The exhaust is suppose to between 300 and 500 degrees before the catalytic converter and 500 and 1500 degrees directly after, If I remember correctly. If the exhaust is under temp. the fuel is running too lean, and needs to be adjusted. If the temp. is too high, the fuel is too rich and needs to be adjusted. Now for the confusing part. On the cars that are E. F. I., the timing plays and important part in fuel delivery. So the O2 sensor sends the signals to the computer and it makes the adjustments, fuel, timing or both.

Will bad ignition coil cause oxygen sensor to fail?
Yes, a bad ignition coil / misfire will cause an unburned mixture of gas/air to go into cat converter which will than combust in it and cause damage to either catalitic converter, oxygen sensor(s) or both. J.Dropic

Would a rear end accident cause the mass airflow sensor to go bad?
It is definitely possible that being rear ended can cause the mass airflow sensor to go bad. If the exhaust system has been damaged, it will effect the airflow. Also the impact itself may have jarred the sensor loose.
Hey guys having trouble with my peugeot experet van It starts but runs terribly misfires coughs and splutters Yet when you hold the accelerator down it seems to run ok for a period till it dies?
The problem with the Peugeot Expert Van might be the MAP Sensor or the Oxygen Sensor. Oxygen Sensors cause the engine to be starved of oxygen when they go bad.
How does a cam sensor go bad can it be due to lack of oil at all?
Engine sensors will only "go bad" from environmental effects. Lack of oil causes excessive heat. Heat can cause cam sensor failure
Could a crank shaft sensor cause my 2005 Nissan Maxima to go into limp mode?
A bad crankshaft sensor would stop the engine and not restart.
How do you know a car oxygen sensor malfunctions?
Go to the auto parts store and buy a scanner OBD1 or OBD2 and it will let you know why your check engine light is on and if the o2 sensor is bad
