Previa engine stalls at idle
Summary of the thread
A 2003 Toyota Previa is experiencing engine stalling at idle, accompanied by a check engine light. The issue is suspected to be related to the tank ventilation system. A similar case suggested checking for clogged hoses connected to the fuel tank and the possibility of a faulty tank ventilation valve. After a workshop diagnosis, the problem was confirmed to be a faulty tank ventilation valve, likely caused by clogged hoses, and was resolved.

Thank you for your reply. Where exactly are those hoses located? Are there any other signs I should look for?

They are connected to the fuel tank. I'm not sure about other signs, but it could be the tank ventilation valve itself. I'd suggest getting a proper diagnosis at a workshop; it cost me 175€ to get it fixed.

Thank you for the advice. I took it to a workshop, and you were right: it was a faulty tank ventilation valve, likely due to clogged hoses. The error message is now gone. I appreciate your help.

I had a similar problem with my Previa. The hoses for the tank ventilation were clogged, triggering the engine light and idle stalling. Check those first.
