I am having trouble with my defi oil pressure gauge. My car was sitting for 6 months and once i started it up, it started to act up. Im not sure if the gauge is reading properly, at idle it wil be at 25psi but once i shut the car off, it doesnt go back to 0, it stays at 50psi. Any help will be appreciated. I did all my researching and cant find to solve the problem. I have the video on the bottom.

Isn't there a way to reset these?

 

Have you tried unplugging the gauge completely and see if it rests at zero. That'd be where I'd start. At least then you'd know if it's the gauge or if it's the wiring/sensor.

 

I did a method. Set warning, hit rec and down switch and that's just setting the warning only. Still went back to 55psi

 

the gauge will rest at zero when their is no power and the car is completely off. I unplugged it and it just turned off and went back to 0. Something simple has to be wrong... I'm just seeing if anyone else had this problem b4

 

Fixed this problem. I had the turbo and oil pressure plugs switched up. Now my defi controller beeps now to verify the oil pressure gauge is on only on the accessories mode not when the cars on. The boost gauge doesn't go all the way down now... It's stuck at 0 psi. Is this normal? Isn't it suppose to be all the way down to the bottom?
