Do you need to replace your oxygen sensor?
Replacement of good oxygen sensors is one of the common mistakes that both seasoned auto repair mechanics and do it yourself driveway mechanics will make when tackling rich or lean diagnostic codes. I am not saying that these O2 sensor codes never require the replacement of the sensor itself.
Why is my fault code and O2 sensor melted?
In fact, the fault code and melted sensor meant that the problem was a lean condition that needed to be resolved. A lean mixture can cause very high combustion chamber temperatures and can also melt spark plugs. If you find a melted o2 check the spark plugs also.
What does O2 sensor code 08-s-05 mean?
The Ford recall number is 08-S-05. Another thing I would like people to understand is the O2 sensor code does not mean it’s time to replace the sensor. It means that it’s time for some diagnosis and repair. If the diagnosis leads to a replacement of an oxygen sensor that is just fine.
Why is the oxygen sensor on my car not working?

How does one check the O2 sensors?
Testing (O2) Oxygen Sensor Voltage Signals Start the engine and check the sensor voltage signals on your voltmeter . The sensor voltage should cycle or fluctuate within the 100 mV-900 mV (0.10 to 0.90V) range. Hence, This means the sensor is operating properly.
What is a bad O2 sensor?
Bad O2 sensors are one of those car problems that most drivers tend to postpone until more serious problems occur. These symptoms will rarely cause any immediate damage, but over time, if left unattended, they can cause damage to the engine and other systems mainly through improper air-fuel mixture.
When to replace O2 sensor?
Car manufacturers recommend replacing the O 2 sensor about every five years (one- and two-wire sensors) or 10 years (three- and four-wire sensors). However, silicon or carbon soot may cover an oxygen sensor due to a car repair or engine performance problems.
Where is the oxygen sensor located on the engine?
Oxygen sensors O2 sensors will always be located in the exhaust system. Their function is to sense how much oxygen remains in the exhaust that is flowing out of the engine, and report that information to the vehicle’s engine control computer.
