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?

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?
