Rubbish sub-standard sensor which failed on installation.
Rubbish. After the hassle of fitting it to a Ford Focus mk2.5 1.8 Duratec, the barometric pressure wasn't matching. Gave it a few hundred miles to "bed in" but car misfires and runs rough at idle when the one I removed didn't so cheap replacement. Was just past the 30 days to return or I would've.
Once again, "Buy Cheap, Buy Twice". you'd think I'd learn.
