Saturn P0404

My daily commuter, a sweet manual Saturn SC2, has a repeated check engine light. It shows a P0404 which indicates an 'EGR Range/Performance Error.' It also sometimes gives a P1404, which is a manufacturer specific version of the EGR code.

I tried cleaning the EGR and replacing the gasket this weekend. It was very cruddy. The pintle valve was pretty stuck, but after pushing on it with a pick, it was able to move freely again.

However, I got the P0404 error on every afternoon commute this week, for a total of three. So cleaning it wasn't the problem. Rockauto had a new Delphi unit, which I have ordered. I was able to get it for $66.17 shipped using the discount code from this site's 'General Forum.'

So we'll see if that works. Stay tuned for the other error code, which is far more challenging.

On the Maxima I had to perform pretty significant cleaning to remedy the EGR issue. I did not replace the valve. This is obviously a totally different engine but don't rule out the possibility of having to clean things on the engine side.
