Hello Members,

I am getting P0404 fault code in my Mazda bt50 2010 3l diesel. Previously coolant loosing and engine hit up issues which fixed by changing new head gasket, water pump, thermostat and fan. Also, replace new EGR valve and EGR coolant. Car is running well but getting engine light and fault code P0404. Mechanic has checked wiring also but no success.

Can someone please help me if they come out from similar issue?

Thanks in advance!

 

Welcome to the forum

 

These do have issues with the EGR valve control solenoid valve on the LHS of the engine bay.

 

Thanks for the reply and suggestion. I will consider it and update here.
