Default 2000 Odyssey, Check light, p0401, replaced EGR, light back on.
Hi there,

My brother's 2000 Odyssey had a check engine light on, the code was p0401.

I had the exact same code on my 99 accord ex, so I replaced the EGR valve. Reset the light, no problems since.

I repleced the EGR in his van, reset the light, and a few days later the light came back on - same code.

Any ideas?
