P11AA error code

Hello, I am getting the code P11AA and the fan is running constantly, when I delete this code, the fan stops. Does anyone know what the error is?

Hello, have you checked the engine cover of your vehicle, if there is air leaking from somewhere, you can check that as well.

It was giving such an error because it was taking air from the upper rocker armature horn, just as you said, the problem is solved.
