Lova check engine light air leak

I also own a Chevrolet Lova, and what you describe sounds oddly familiar to what happened to me a while ago. If I understand correctly, you suspect an issue with the air valve. Have you noticed any other symptoms, like rough idling or engine stalling? Could you check the air intake for any cracks or loose connections? Sometimes, a simple air leak after the throttle body can throw off the whole system. What are the exact error codes you're seeing?

Thanks for the quick reply! No rough idling or stalling that I've noticed. The error code refers to an air leak. Where exactly should I be looking for cracks or loose connections near the air intake?

Since it's indicating an air leak and you're suspecting the air valve, I'd advise you to inspect all the hoses connected to it very carefully. Basically, trace everything connected to the air valve itself. If you're not comfortable doing that, the best course of action would be to take it to a trusted mechanic to get a professional diagnosis. It might save you some trouble in the long run. Hope you get it sorted!

Appreciate the advice! Turns out, it was exactly as suspected – a defective hose connection between the pump and the air valve. Had it replaced at the workshop, cost me about 175€ all in. Check engine light's gone, and the car's running smoothly again. Thanks again!
