The code P0401 is listed among other possible codes. The repair again involves cleaning the EGR ports. Toyota Camry/Corolla: In Toyota Camry with the 2.2L engine, the code P0401 was often caused by a bad VSV (Vacuum Switching Valve) for the EGR, located under the intake at the back of the engine.
如果蓋子類同這個,中間裏麵有彈簧(不清楚2000的車有沒有)。換蓋子是最方便的一試,無果的話,換EGR parts...

一定得有弾簧才能密封
