Quick question.

I have a 2005 base model cobalt. How many o2 sensors do I have? I know I have one on the downpipe that I can see but I cant get far enough under the car to see if there is one on the exhaust mani and I dont feel like jacking the car up just to check. Can anyone chime in and let me know if there is one or two o2 sensors.

 

2, one on the mani and one on the DP.

 

Thanks, just wanted to make sure.

 

Bung!

 

Not a problem bro, it is on the driver side of the mani about an inch and a half above the DP flange.

 

Yeah I just needed to know if I had to have a shop weld a bung on for me for my wideband. I wasnt sure if I only had one or two so yeah, looks like im going to have to get a bung welded.
