23222, What's the DTC code P0401 and how do you fix it?
Posted by JUNJUN712, May-27-02 04:20 PM
Will I bought an FCD(fuel cut-off defender) hook it up then later on in the afternoon the engine light came on. I check it, turns out to be P0401. Anybody have this problem before? BTW, I have a star stage II boosting at 6psi. Thanks for any help...

off the top of my head, 401 is EGR malfunction... i wudnt worry unless u experience performance problems when u get a CEL.. definately find out for sure what that code is... look at darkones FSMs...

P0401
Exhaust Gas Recirculation Flow Insufficient Detected
try cleaning out the EGR solenoid/valve or did you do the block off mod
