keo Posted July 8, 2016 Share Posted July 8, 2016 Going to work this morning my digital temp was blank blank, not 0, just nothing displayed at all. When i got work (50 miles so it should be up to temp!) i turned it off and on and it showed 72. Turned it off and on again and it went blank again. Car is a 2005 111R Toyota engine. Any ideas?

russelld Posted July 9, 2016 Share Posted July 9, 2016 It could be the thermostat is stuck open so the engine is never getting hot enough to kick in the temperature guage, I think it comes on at 72deg. If you let the car stand ticking over for 15-20 mins after a drive it would then definitely get up past 72 deg. If still no display it would indicate another problem, earthing, electrical connections, sender unit gone down, ECU problem, dash problem ?
