What happens when the O2 sensor goes bad on a Chevy S10?
Oxygen sensors play a vital role in both engine management and emissions control. When an O2 (oxygen) sensor go bad, it’ll cause your Chevy S10 ‘s engine to run less efficiently. Your S10 can exhibit symptoms when the Oxygen sensor has gone bad.
What happens when an oxygen sensor goes bad?
Oxygen sensors play a vital role in both engine management and emissions control. When an O2 (oxygen) sensor go bad, it’ll cause your Chevy S10 ‘s engine to run less efficiently. Your S10 can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all.
Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
Why does the Check Engine light come on on my S10?
Oxygen sensors can change the way that your S10’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
Where are the O2 sensors located on a Chevy Silverado?

How does the O2 sensor work on a truck?
