Volvo17235 Posted November 15, 2011 Report Share Posted November 15, 2011 The ETS light came on in my 1999 volvo s70 recently. However the car is showing no symptoms of having a bad electronic throttle module. If i unplug the battery and plug it back in the light goes off but it will come back on when the car reaches 40mph. Any ideas of what could be wrong? Maybe a bad sensor? Any help would be appreciated thanks! Link to comment Share on other sites More sharing options...
Dan A Posted November 17, 2011 Report Share Posted November 17, 2011 First step is to get the codes pulled to find out why the light is illuminating. Link to comment Share on other sites More sharing options...
