i have a problem with my Oil Pressure Gauge.
Since i have the Car it ever showed me full oil pressure even if i haven't start the car. --> bad oil pressure sender.
So i changed it, and the new one shows me zero Oil Pressure. If i hit the Gas the needle is moving nearly a half of a millimeter not more... But in fact of the low pressure it shows SES...
Because i worried about the bad oil pressure i checked it with a manual Oil Pressure Gauge and it shows me around 5 Bar = 500kpa = 72psi when it idles and even more when i hit the gas, so every is perfect. And the engine runs great.
BUT where could be the problem? Is it the Gauge itself? Is there a way to test it?
The Cable to the Pressure sending unit has 4 wires, is there a way to test if there is something wrong?
I hope you could help me.
