    P0443 still comes on

    Hi so I put a 2003 LQ9 using a p59 PCM into a truck deleted VATS and DTCs. All have worked but code P0443 keeps coming on. I checked my file and I have it turned off as in the code should not register and I also have the MIL turned off. I'm using TunnerPro OS 12579405. Any suggestions on what I'm doing wrong or how to fix. thank you
