SES light still on????


Recommended Posts

Well I put in two new rear o2 sensors and my SES light is still on.

I have two codes;

P0141

P0161

Is that because of my free flowing exhaust and the converters not being hot enough? Dynatech longtubes, high flow cats, and Corsa cat back..

Is that something that could be compinsated for in the tune?

Thanks, I am just getting sick of looking at the SES light..

if you're running aftermarket cats and longtubes, this is very common. it can also be programmed out by the person that did the pcm tune on your truck. i've ran into that problem a few times.
