Hamilton Posted March 28, 2022 Share Posted March 28, 2022 My Supra has done this for as long as I’ve had it but for some reason it only started bothering me today… When I put the handbrake on the yellow oil level light always lights up, in addition to the normal handbrake light and the general warning light in the middle of the RPM gauge. There has never been any oil problems- it has the right amount, regular changes and no leaks. Am I right in thinking that’s not normal? And if not, any idea what might cause it? I was happier when it didn’t bother me! Quote Link to comment Share on other sites More sharing options...
TuneR Posted March 29, 2022 Share Posted March 29, 2022 Oil level normal? Car on/off? Idling/not idling? Could be the sensor is all. Quote Link to comment Share on other sites More sharing options...
Tyson Posted March 29, 2022 Share Posted March 29, 2022 If nothing seems to be amiss then it is most likely an electrical gremlin somewhere. I would be inclined to say that there is a short circuit somewhere given the oil level and handbrake have nothing to do with each other.

erachter Posted March 29, 2022 Share Posted March 29, 2022 (edited) Try checking the wires and connections(including the ones on the actual light) behind that small cluster with lights. Mine had a bad connection and sometimes the yellow oil level light also was appearing, but I've just connected it better and no more issues after that. Maybe you can try even doing a continuity test to see that they are ok. Or just remove that bulb lol, who needs it anyway, level sensor is not accurate anyway and you have a dipstick Edited March 29, 2022 by erachter (see edit history) Quote Link to comment Share on other sites More sharing options...
Hamilton Posted March 31, 2022 Author Share Posted March 31, 2022 Thanks for the tips everyone- all good suggestions. I’ll definitely check the connections but have a feeling I’m going to end up just living with it. I do know the sensor works for what it’s supposed to as the front crank seal failed a couple of years back and the yellow light warned me, so I’m not too worried. Just a bit annoying to have a light that shouldn’t be on when using the handbrake! Quote Link to comment Share on other sites More sharing options...
