Oxygen sensor

[LC 100 Bat]

Hi all,

How can I make sure the Oxygen sensors are working properly. Is there any way to tell without pulling them out?

Thanks for your help.

Is there a code being thrown? I not they're working correctly. They do tend to get lazy late in life but if they're within spec you won't get a light.

02 sensors either work or they don't work. They will loose their efficiency to monitor over time. As so as it gets out if range it will throw a code. Very easy to replace. A cheap adjustable and some gloves and you will be done in 15 minutes per side.

No, the light didn't come on. Thank you for your advice.

It didn't throw code. That means o2 sensor working properly. I won't touch it. Thanks

Thats some good luck right there^^^.

Mine started life in MI, and when I installed the DT headers I replaced the sensors but decided to pull the old ones from the manifolds....
Vice, and torch did not get the job done and I gave up, now have spare manifolds with semi-permanent old sensors still installed. I didn't need'em so I gave up easy,it could still get done some rainy day.

I know it should be easy but I think it's worth pointing out that it could also be a miserable PITA depending on the age and use of your truck.

Yeah, and if you have fat hands... not so much.

I had to get my wife under there to replace the front ones. As I recall, the back ones are much easier.
