dragon queen Posted July 29, 2011 Report Share Posted July 29, 2011 Hi all can anyone tell me where abouts the oil pressure switch on the engine is, my son in law says a yellow warning oil light (lower left on the dash) is on constant when the engine is hot in his celica 95 uk model gen6 3sge engine. We havent seen it for ourselves as yet, we hope to tomorrow, would just like to have an idea in advance, Link to comment Share on other sites More sharing options...
stevenc1603 Posted July 29, 2011 Report Share Posted July 29, 2011 Yellow oil can I would expect is oil level. Normally pressure is a red one. Pressure switch is screwed into the right hand side of the cylinder head near to the front. Link to comment Share on other sites More sharing options...

stevenc1603 Posted July 30, 2011 Report Share Posted July 30, 2011 Unplugged would be no different to it showing low pressure. Can you check, do you have red and yellow oil can lights, or just one. You should be able to see if you have both when you switch on the ignition. The level sensors are known to be temperamental and can cause issues like showing a fault when there isn't one.

Biggy Posted July 30, 2011 Report Share Posted July 30, 2011 Pretty sure yellow is oil level Link to comment Share on other sites More sharing options...
sbdags Posted July 30, 2011 Report Share Posted July 30, 2011 It's a very common fault on the gen 6. The level sensor just goes and then the alert plays up. You can buy a new one (expensive) or take the bulb out of the dash (cheap). Either way as long as you check the oil level regularly it won't be an issue.

dragon queen Posted July 30, 2011 Author Report Share Posted July 30, 2011 Thanks for the advice, had a tinkle with the sensor earlier tried half heartedly to remove it and chickened out, is very very tight, and made me nervous of snapping it off, still cant figure out the size of it couldnt find a deep metric socket to fit properly, had to use an old imperial one. Will take your advice and remove the bulb, on a positive note it means ive got a spare bulb now. Link to comment Share on other sites More sharing options...
keef-b Posted July 31, 2011 Report Share Posted July 31, 2011 3SGE engine? Oil level sensor is on the sump near the drain plug if i remember right. They do go and will illuminate the orange light as stated above. The pressure sensor located higher up on the block/head will illuminate the red oil can warning light and thats the scary one! A new oil level sensor from Toyota is around £130 - alternatively just pull the plug from it, bridge the terminals of the sensor with a bit if thin copper wire and re-attach the plug. Light goes out and as long as you check your oil regularly you are fine - also means ALL the warning lights will still come on when you turn the ignition on Link to comment Share on other sites More sharing options...
