Rostyn Griffiths and Tomi Juric were in action for the visitors, who went ahead in controversial fashion when Edwin Gyasi collected a pass from an offside position and crossed for Joshua Brenet to poke into his own net.
However, Davy Propper was left unmarked from Andres Guardado's free-kick in the 75th minute and he flicked a header beyond goalkeeper Benjamin van Leer to earn PSV a point.
Griffiths played a full game with Juric starting but being replaced with 13 minutes remaining.
The draw left PSV in third place, level on points with Feyenoord and three adrift of Ajax.
Bartholomew Ogbeche scored twice as Cambuur Leeuwarden claimed their first victory of the season to defeat NEC Nijmegen 3-1.
Ogbeche stole in from a back-post corner to break the deadlock and then restored Cambuur's lead after Xander Houtkoop scored an own goal.
Another own goal, this time from Christian Santos, sealed Cambuur's maiden triumph of the season.
Hakim Ziyech's stoppage-time winner earned 10-man FC Twente a 2-1 success over De Graafschap.
The hosts were up against it when goalkeeper Nick Marsman was sent off in the opening half-an-hour and, although Cas Peters missed the resulting penalty, Andrew Driver dispatched the rebound.
Joachim Andersen equalised two minutes later, though, and Ziyech raced through on goal late on and blasted the ball beyond Hidde Jurjus to spark wild celebrations.
It also finished 1-1 between ADO Den Haag and Willem II.
Kevin Jansen's goal 11 minutes before half-time put ADO ahead, but Dion Malone's red card gave Nick Van der Velden the chance to level from the penalty spot and he duly obliged.
