P1404 Saturn 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.

Code P1404 Saturn Description

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. The PCM tests for a stuck valve when the desired EGR position is at 0%. The PCM commands the EGR valve to 100% during certain driving conditions in order to clear a possible restriction from the EGR valve if the PCM determines that the valve is stuck open. The PCM retests for a stuck valve when the desired EGR position returns to 0%. A failure timer increments if the stuck EGR valve condition is still present. This Diagnostic Trouble Code (DTC) sets when the timer reaches a predetermined value.
