Quick pic I took where I think maybe the possible location of my 02 sensor on my 95 2wd extended cab Silverado. This was on the drivers side manifold near the spark plugs....am I right??? LOL...hope so? I've looked around near the cat but couldn't find anything.... Thanks in advance!

 

im going to say yes thats the o2 sensor,iv'e noticed that some the 4.3 liter's have them in the exhaust pipe and others have them into the exhaust manifold.....could you possibly take a better pic?

it looks like your pointing at the temp sensor. possibly a knock sensor. it looks like it is in the head not the manifold

 

Definitely not the O2 sensor. Look like the temp sensor. The O2 sensors are down stream for the manifolds in a exhaust pipe.

 

Temp sensor for sure !

 

I have a '94 Silverado and the O2 Sensor is located right after the Y-Pipe before the Catylic Converter. The O2 Sensor is top side of the Pipe so you will need to look at it at an angle rather than directly under the exhaust. What you are actually pointing at is not the "Temp Sensor" as used by the ECU but the Temp Sensor for the Temp Guage (Single Wire). So if your guage is not working now you know where to go!
