This GM's definition of this code:
P1404 - Exhaust Gas Recirculation (EGR) Closed Position Performance
The most common reasons are either the EGR valve position sensor is defective, or the EGR valve is not fully closed due to carbon.

there are a couple of things, first make sure there are not restriction in the exhaust, i know the dealer has had to replace converters under warranty because of this problem, then theres a reflesh program for the computer due to this problem, and lastly,run with egr off make sure it clean of carbon,carbon gets stuck in pintle sets check eng lightbut carbon then blows by so when you remove egr you see nothing, well start with these good luck.

You can reset it with a scanner through the diagnostic port or you can disconnect the battery negative cable for 5 minutes or pull the ECM 1 and 2 fuse for 5 minutes.

P1404 error


The code is saying the egr pintel valve is stuck open. There are probably carbon deposits around the bottom keeping it from closing properly. Take it off and try cleaning-scrape the deposits off. And check the exhaust passages the valve controls-scrape those clean as best you can. You will see them when you take the egr valve off.

P1404 is EGR valve stuck open. Probably need to replace your electric EGR valve. First, I would remove it and clean the carbon out of it before replacing this expensive part.
