Question

I got the engine code P0404 on my 2008 Honda Accord, what is the best solution?

Answer 1

HI there

This code is for the EGR valve performance.

This is normally the result of a faulty egr valve or the wiring for the egr valve. Sometimes the egr temp sensor will also cause this code o appear. If the sensor isn't reading properly then it will cause the code. Also check for a blocked egr tube.
