What does a p1404 code mean?

P1404 is a code for the EGR valve. This code indicates the pintal in the egr is not moving properly. This could be caused by a couple things. First, the egr port could be blocked, then when the egr valve opens the map sensor doesn’t sense a pressure change and will set the code.

What is the OBD p1404 fault?

What does p0404 OBD code mean?

OBD-II Code P0404 is defined as a Exhaust Gas Recirculation Circuit Range/Performance NOx gases, which cause acid rain and respiratory problems, are formed when the engine’s combustion temperature is too high (2500° F). EGR systems are used to reduce the combustion temperature, thus reducing NOx formation. Aug 12 2019

What could cause the code p0401?

Code P0401 is triggered when the EGR temperature sensor does not see enough of a temperature change when the EGR is commanded to open. These sensors tend to get a lot of carbon buildup that causes them to lose sensitivity to the heat from the EGR gases.

Trouble code P1404 describes a problem called “exhaust gas recirculation closed position performance.” When exhaust gases are produced by the internal combustion process of a gasoline engine, there is an exhaust gas recirculation system which redirects a portion of those gases back into the cylinders of the engine. This helps promote fuel efficiency while reducing carbon emissions.
