Maxima check engine light
Summary of the thread
A 2022 Nissan Maxima displayed a check engine light at 150,269 km, suspected to be due to an air valve issue, possibly from a faulty hose connection. The problem was linked to rough idling, especially when the engine was cold. After advice to inspect vacuum hoses around the air intake, it was confirmed that a defective hose connection from the pump to the valve was the cause. The issue was resolved at a workshop, eliminating the check engine light.

Yeah, I'm getting some rough idling, especially when the engine is cold. Where exactly should I be looking for these hoses? Any specific areas that are prone to failure?

Honestly, it was a pain to find the leak on mine. It's probably best to take it to a workshop if you can't spot anything obvious. It's likely a cracked or disconnected hose somewhere in the air intake system, leading to the air valve. Cost me around 175€ to fix.

Thanks! Took your advice and brought it in. You were spot on – defective hose connection from the pump to valve. Exactly 175€. Check engine light gone. Appreciate the help!

I feel your pain. I had something similar happen on my Maxima. Check those vacuum hoses, especially around the air intake. Are you having any idle problems or engine stalling?
