FAQ:

Q: What happens when the O2 sensor on a Chevy S10 goes bad?

A: 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.

Q: Which side of the engine is the oxygen sensor located?

A: For instance, an oxygen sensor at bank 1 – sensor 1 would be: Bank 1- Side of the engine with the first cylinder in the firing order. This means that you need to look up the firing order for your particular model year and engine.

Q: Why does my check engine light come on in my S10?

A: 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.

Q: How do you know if your oxygen sensor is bad?

A: One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. The smell is often described as “rotten eggs” or sulfuric. Either way, like with rotten food, “the nose knows”. Without the proper air/fuel mixture, your engine won’t run as smoothly as it should.
