What does fault code P0404 mean?

When P0404 is triggered, it means that the PCM has been told that the valve is performing in a way that is outside of its specified parameters. More specifically, the PCM has been told that the valve is closed when it should be open, or vice-versa.

How do you fix a EGR circuit fault?

What repairs can fix the P0403 code?

  1. Replacing the shorted or open EGR vacuum solenoid.
  2. Replacing a corroded connector to the EGR vacuum control solenoid.
  3. Repairing the wiring shorted to the EGR vacuum control solenoid.

What can cause a P0404 code?

Causes of Code P0404

  • A faulty EGR sensor.
  • A bad EGR valve.
  • Rough EGR valve movements.
  • Problems with EGR sensor wiring and connectors.
  • Carbon build-up in the EGR valve.

Where is the EGR solenoid located?

It is normally attached to the engine block with a nut and is close to the EGR valve. The solenoid can be located by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid. Replacing the EGR solenoid can be done in just a few minutes and you can save time doing it yourself.

What does the OBD fault code p0404 mean?

P0404 is a generic OBD II fault code that indicates that there is an issue with the Exhaust Gas Recirculation (EGR) circuit. The Engine Control Module (ECM) has detected that the EGR circuit is either out of range or not functioning properly. The purpose of the EGR system is to burn fuel more efficiently.

What is the OBD code for exhaust gas recirculation?

All our repairs are backed by our 12-month / 12,000-mile warranty. P0404 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve or sensor is out of specification range or its performance has gone out of specification parameters.

What does p0404 mean on an EGR valve?

EGR (Exhaust Gas Re-Circulation) systems are used to reduce the combustion temperature, thus reducing NOx formation. Code P0404 means that the EGR Valve Position Sensor is reading above or below the specified range.

What does DTC stand for in OBD-II?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The EGR (Exhaust Gas Recirculation) system’s purpose is to redirect exhaust gas back into the cylinders.
