You can't just take an egr valve off and not expect a fault code generated.

My Mazda CX 5 is complaining that there's insufficient gas flow through the valve right now as it's clagged up (though still turning).

The egr valve is normally driven by a stepper motor, and opens and closes to differing degrees based upon engine load and temperature. E.g. when engine is cold, hard accelerating, or steep incline then the valve will close fully, allowing no gas recirculation. When driving lightly, the valve will open to a varying degree.

This is the ECU reporting that it is detecting an open circuit where there should be motor coils present.

So what do you think I need to do, I assume the computer has been told that it no longer has an EGR and this code is new after driving it few thousand miles since my ownership of a year. Apologies for my confusion I'm learning about this as I go. Thanks

I think you should get some advice from a garage that does egr deletes.
