P0401 - EGR Valve FLOW.
This is when I found and changed the exploded hose and after that I pass the fumes test. But shortly after the lproblem came back, and the "check engine" light came back on, and the engine dont run that well, especially when it is hot outside.
I foundthat the code 401 means:
Exhaust Gas Recirculation Flow Insufficient Detected.
How can I fix this, changing the EGR VALVE will be enough?
have the same problem?
