Hi Terrence, I'm glad to help you out. The common causes of the code P0400 are clogged/damaged egr valve, worn-out vacuum lines, or the egr temperature sensor. We suggest that a certified mechanic diagnose the vehicle to pinpoint the part that needs replacement.

Hello! A faulty EGR valve is just one of several potential causes of code P0401. Toyota vehicles are well-known for having problems with the EGR Vacuum Switching Valve (VSV), which could also trigger code P0401. To know the true cause of the code, you (or your mechanic) will need to do some troubleshooting.

My mechanic said I need a EGR valve we just replaced the carbon canister should I get the EGR VSV code P0401
