Previa engine stalls at idle

I'm experiencing a problem with my 2003 Toyota Previa (gasoline engine). The check engine light comes on and the engine stalls at idle. The car has 57916 km. Could this be related to the tank ventilation? I have checked the pressure sensor, but I did not find any obvious problem.

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.

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.
