P1404 Saturn Code - Exhaust Gas Recirculation Closed Position Performance

Quick Answer

The P1404 code for Saturn vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) system's closed position performance. Common causes include Faulty EGR valve, EGR valve stuck open or closed, Carbon build-up in the EGR system. 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 P1404 code for Saturn vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) system's closed position performance. The EGR system plays a crucial role in reducing emissions by recirculating a portion of the engine's exhaust gases back into the combustion chambers. This process helps lower the temperature of combustion, reducing the formation of harmful nitrogen oxide (NOx) emissions.

Common Causes of P1404 Saturn

  1. Faulty EGR valve
  2. EGR valve stuck open or closed
  3. Carbon build-up in the EGR system
  4. Vacuum leak in the EGR system
  5. Wiring or electrical issues with the EGR valve

Symptoms of P1404 Saturn

  1. Check Engine Light illuminated
  2. Reduced fuel efficiency
  3. Engine misfires or rough idling
  4. Increased emissions during emissions testing
  5. Reduced engine performance

How to Fix P1404 Saturn

  1. Diagnose the EGR system: Use a scan tool to check for any stored fault codes and perform a visual inspection of the EGR valve and associated components.
  2. Clean or replace the EGR valve: If the valve is stuck or not functioning correctly, it may need to be cleaned or replaced.
  3. Check for vacuum leaks: Inspect the vacuum hoses and connections in the EGR system for any leaks or damage.
  4. Clear the EGR passages: Remove any carbon build-up in the EGR passages to ensure proper flow of exhaust gases.
  5. Reset the ECU: After completing repairs, clear the fault code and reset the Engine Control Unit (ECU) to see if the issue has been resolved.

Cost to Fix P1404 Saturn

The cost of repairing a P1404 code on a Saturn vehicle can vary depending on the specific issue and the labor rates in your area. On average, the cost of replacing an EGR valve can range from $150 to $400, including parts and labor. If additional repairs or cleaning of the EGR system are needed, the cost may increase. It's advisable to consult with a certified mechanic or auto repair shop for a more accurate estimate based on your vehicle's make and model. Labor rates typically range from $80 to $150 per hour, but can be higher in metropolitan areas or at dealerships.

Tech Notes for P1404 Saturn

On some models, there is a service bulletin for the P1404 code that suggests reprogramming the Powertrain Control Module (PCM) to repair the problem.

When is the Code Detected?

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.
