Procedure; Human Factors
On the NNCEE 1 Arrival ATC changed our runway and approach from ILS 8R to RNAV (RNP) Y RWY 9. I selected this approach in the FMC and selected HOWLN transition. I looked at my map screen and saw it all there. I sat there and watch the plane not make the turn at and went to HDG select to follow the magenta line. I did this within a second or two as I was just watching the map mode. As I was in the turn ATC said you appear to be slightly off course; you are cleared for the visual RWY 9. We did the visual.
B737NG First Officer reported a track deviation occurred following a last minute clearance change to the RNAV (RNP) Y Approach to Runway 8R in IAH.
