We were on vectors for Runway 26. We were given probably 6+ headings changes; along with altitude changes; within a minute's time. I'm not sure what the problem was. My guess is Approach wanted us to turn at a faster rate. The autopilot was on and turning at a normal 30 degrees [bank angle]. After about the 5th heading vector; I just clicked the autopilot off and turned at 45 degrees [bank angle] and that seemed to make him happy. We were hitting some wake turbulence during this time that may have been a factor. We never went past the final approach path/runway extended centerline; and we were cleared for the visual and landed without incident; so I'm really not sure what the problem was but we were told to call the number for a possible pilot deviation. It felt like we were just getting bad vectors.
B737 First Officer reported encountering wake turbulence on arrival into PHX that may have led to a track deviation.
