I've tried a few searches with different parameters, but I've yet to find the answer to this question.

I've got a CE with a 45 error code (Atmospheric pressure sensor).

Any idea as to what this is and how to fix/replace it?

Thanks in advance.

On the first gen legacies the atmospheric pressure sensor is located in the ECU. It is not repairable, you must replace the ECU.

I'd suggest clearing the codes, see if it comes back. If it does, try and find a used ECU at a auto parts yard.
