Check Engine Code P1673 on a 2000 Sephia

[nessamarie]

My check engine light is on in my 2000 Sephia. I went to Auto Zone and the code they pulled was P1673 but they couldn't tell me what it meant. I called the dealership, but they wouldn't tell me either unless I bring my car to them for whatever needs to be fixed. I'd rather just fix it on my own once I know what the code is signaling. Does anyone know what code P1673 means or would it be different for each diagnostic? Thanks for any help you may have.
