What is code 1404?
What is code 1404?
|P1404 CHEVROLET Meaning 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.
What is the OBD 2 fault code 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 Control Module)…
Is there a service bulletin for the p1404 Pontiac?
On some models, there is a service bulletin for the P1404 code that suggests reprogramming the Powertrain Control Module (PCM) to repair the problem. The cost to diagnose the P1404 PONTIAC code is 1.0 hour of labor.
What causes the VCM to set the p1404 DTC?
SEVERE OCCURRENCES MAY CAUSE THE VEHICLE CONTROL MODULE (VCM) TO SET A P1404 DTC BECAUSE THE VCM PERCEIVES THAT THE EGR VALVE IS STUCK OPEN. 1. USING THE TECH 2 SCAN TOOL, EXERCISE THE EGR VALVE, AND VERIFY THE [EGR] VALVE’S ACTUAL AND DESIRED POSITION TRACK.
What is the closed position of the EGR valve?
While monitoring the Exhaust Gas Recirculation (EGR) valve pintle position the Powertrain Control Module (PCM) detected the closed position sensor voltage higher than the learned closed position voltage.

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%.
