CODE PO400

1995 Nissan Sentra

What to do next after replacing ERG valve? The check engine is still lite. Do the computer need to be reset? Or do I need to do something elese? I just bought the car three weeks ago from an auction so not much history.

Reset the ECU by disconecting the -ve battery cable. If the code come back then u wanna find out why the computer is getting a signal that indicate the EGR system is notfunctioning properly. Ta da.
