What code is P1404?
OBD II fault code P1404 is a manufacturer specific code that is defined by General Motors (Chevrolet in particular) as “Exhaust Gas Recirculation (EGR) Closed Position Performance”, and is set when the actual position of the EGR valve pintle does no coincide with the position of the EGR valve pintle the PCM (Powertrain …
When does the EGR valve get stuck open?
The Powertrain Control Module (PCM) determines that the EGR valve is stuck open if the actual Exhaust Gas Recirculation (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%.

Is there an OBD code for exhaust gas recirculation?
SPECIAL NOTES: OBD II code with the definition “IAT [Intake Air Temperature] – B Circuit Malfunction / Exhaust Gas Recirculation Closed Position Performance” is mostly relevant to some General Motors (and a few European) products from the late 1990’s to the early / mid 2000’s, and is therefore no longer in common use by most manufacturers.
What kind of EGR valve do I Need?
NOTE: This guide will focus only on “Linear (Electronic) EGR Valves”, which is the type of EGR valve most commonly used on applications dating from the early 1990’s to the present.
