Alan Browne scored the winner, the PNE skipper netting from the penalty spot after Ched Evans had been fouled by Sky Blues goalkeeper Ben Wilson.
Victory ensured Championship football for North End next season, Frankie McAvoy's record in charge being three wins, two draws and one defeat.
These are the North End player ratings, Ched Evans and Browne the stand-out players.

Another change of position, playing at left wing-back after being up front in midweek. Energetic down that side of the pitch. Photo: Camerasport

10. Sean Maguire 6
Put a first-half header wide when he should have done better. Worked hard up front and showed some nice touches. Photo: Camerasport

11. Ched Evans 8
Powerhouse performance in attack. Won PNE's penalty and should have had another. Caused lots of problems for the Coventry defence. Photo: Camerasport

12. Emil Riis 6
Came off the bench to replace Maguire just moments before PNE scored. Took the ball into good areas as North End saw the game out. Photo: Camerasport
