Today I removed the EGR valve, there was some carbon, but not much. There
was only a think layer of carbon. I cleaned it up. I did reset the light,
and now waiting to see if the light comes back. If the light comes back,
does it necessarily mean that a new EGR valve will solve it? Thanks.

How many miles are on the car? With the engine idling, apply vacuum to the
EGR valve and see if the engine starts to idle roughly or start to die. If
that happens, check the EGR position sensor. If the engine does not start
to die, check the EGR tube for blockage. Most likely, the EGR tube is
blocked with carbon buildup. If that is the case, you can try to dig out
some of the carbon or replace the EGR valve and tube.

Hello,
My Camry '97 just failed inspection. It is code P0401. 'Exhaust Gas
Recirculation Flow Insufficient Detected.' Would you please give me your
recommendations.
Thanks,
