Hi guys, I suspect my oil pressure gauge to not work, it always show zero and it never moves, not even a bit. The engine seems to run fine, I came back from holidays with my celica, on the way back I noticed this problem, so I didn't rev the car over 3K. I suspect some kind of connector that is not plugged properly. Recently we swapped the gearbox for a S54. we probably forgot to plug something. (mostly my friend who is mechanic did the job) I think the signal is electric, right ? Can someone tell me where are the plugs ? (maybe with pictures ? ) I tried to search the forums before posting, but didn't find anything. If ever, is there some kind of procedure to check the oil pressure another way than by the gauge ? Thanks.
The oil pressure sensor is above the cooling neck, a mushroom-like thingy sticking out from the side of the head You can see it on the right side of this picture, below the distributor and above the water hose: PA280010.jpg
Thank you so much LionTR, you're the best !!! At first I didn't understand, then I noticed that something should be plugged on the "mushroom". The brown plug was plugged instead of the blue, the blue wasn't plugged. For other ppl, it might be useful: just plug the brown on the "Mushroom" and the blue on the pipe.
