Hello, this code showed up as pending in which i’m a little confused about it. I have a slight exhaust leak at the manifold which could be causing it but i’m not sure. It could also be a vacuum leak aswell. My question is, does the exhaust leak at the manifold cause this? There is also no loss in power. The code says post catalyst, but that’s pre catalyst so i’m not sure. Any help is appreciated!

 

The sensor is post catalyst but the issue is anywhere upstream from there. I would guess it's related to the exhaust leak.

 

I fixed it with replacing the solenoid. It wasn’t opening up so it sounded like the air pump was going to blow up 😂. Now it sounds fine and I haven’t had a CEL come back yet.

 

Which solenoid did you replace to solve the issue?

 

It was the “Air Solenoid Valve” according to the diagrams. It’s the solenoid on the top of the 3.
