P1404 Chevrolet Code - Exhaust Gas Recirculation Closed Position Performance
Quick Answer
The Powertrain Control Module (PCM) determines that the Exhaust Gas Recirculation (EGR) valve is stuck open if the actual EGR position and the learned closed EGR position vary by more than a predetermined value. Common causes include Carbon blockage of the pintle, Faulty Exhaust Gas Recirculation (EGR) valve. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

I just replaced the egr valve about 7 months ago now all of a sudden truck is making an intermittent leak/purging sound (same sound as a pressure cooker) and the check engine light is on. Checked codes and had po141 (o2 sensor problem) and p1404 manufacturer code. I erased codes and sound went away. I haven't driven enough for the codes to come back yet
