Integra air valve issue
Summary of the thread
A 2004 Honda Integra had a check engine light issue, with a scanner indicating an air valve problem. The owner suspected a vacuum leak between the pump and the valve. Another person with a similar experience suggested checking the hose connection from the pump to the valve, as it might be letting air in due to hardened rubber. Upon inspection, the hose connection was indeed the issue, and replacing it resolved the problem, clearing the check engine light.

Interesting! Do you recall what the hose looked like? Was it cracked, or just a loose connection? Any specific area I should focus on? Trying to avoid engine stalling.

It looked fine, but it was letting air in. The rubber hardens and doesn't seal. Just go to your workshop and tell them the problem. They will know what to do.

You were spot on. It was the hose connection. Replaced it, and the check engine light is gone. Cost me 175€. Appreciate the help!

Integra here! Exact same thing happened last year. Check the hose connection from the pump to the valve. Seriously, I bet that's it!
