What are the symptoms of an oxygen sensor going bad?
Here are some of the most common signs that your oxygen sensor is bad.
Check Engine Light comes on--The first line of defense is the Check Engine Light. The Check Engine Light will illuminate if you have a bad or failing oxygen sensor.
Bad gas mileage and rotten egg smell--If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems
will be thrown off. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust.
Rough engine idle and misfires--Since the oxygen sensor output helps control engine timing, combustion intervals,
and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle and other engine-related issues.
