They can have problems related to corrosion because of the heat and the differences in metal between the exhaust system and the case metal on the sensor.
Before you mess things up really bad get a tap for the size threads on your O2 sensor and clean out the old threads with it, being careful not to really cut new ones just clean out the old ones.
When the oxygen sensor goes bad, the check engine light goes on.
When an oxygen sensor goes bad a car will burn gas at a higher than normal rate because it will not be producing as much power as before. The oxygen sensor checks the amount of exhaust.
An auto xray scanner can determine if a O2 sensor is bad.
It sure can.
When you have a bad oxygen sensor your car may consume a lot of gas. Your car may also drive slower.
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
