Mitsubishi: 2001 Eclipse GT - P0403 error code

If you used an aftermarket PCV I would be suspicious. In my limited
experience they tend to be leakers. I would soak the original one
(hopefully OEM) in some solvent blow it out with air and reinstall. Who
knows??

Ah, too late. I changed it Wednesday, and the trash came Thursday.

The PCV valve isn't connected to the EGR in any way. It doesn't need
changing ever, really. It is a check ball inside a housing. Blow and suck on
it for the click sound and you know it's ok. If not, clean it out with brake
parts cleaner. That's all it takes. Its really a big scam at oil change
places.

Now, you changed that and the filter, well guess what? There are hoses off
the intake that feed into the EGR. Check that.

If that Eclipse is mid 90's with the vacuum actuated EGR any vacuum
malfunction or leak will affect the EGR performance to some degree.

No it's a 2001. I checked all the hoses - everything looks fine. I cleared
the code Thursday, but today the light came back (actually two readings of
the same code), so it wasn't some random reading. I'm going to dig a bit
further tomorrow.
