Narrative:

We were descending on the peekk 3 RNAV arrival into den. At around 17;000 ft we talked to approach control and were given the RNAV (rnp) Z 16R. We were expecting the ILS 16R; so the new approach was entered and briefed. Around the same time and in the descent to 11;000 ft we received multiple airspeed changes by ATC. At 11000 ft at cepee aircraft did not turn on course to aagee; but instead continued on a 353 straight ahead course line. We made a manual heading change to follow the correct course within a couple seconds of passing cepee. ATC then canceled the approach and gave us a vector to intercept a visual final for 16R. We intercepted final and landed 16R.
