Technical oil pressure engine dont start

[ruicordeiro1]

my fiat bravo 1.6 multijet 2007 ignited the warning of low oil pressure, stop the engine and turned on the engine and oil light, and the car ran out of rotations, I stopped the car and I started to turn it on a few km come home I checked the level in the morning and it was kind of oil. I went to get the car to work and it did not catch on. I noticed that turning on the ignition the candle light only turns on and when you turn on the car it picks up but the same oil warning appears and the car turns off. does anyone have an idea of ​​what it might be or some advice

When you turn the ignition ON, but the motor not run, the lamp "oil pressure " is ON ( lit ). When motor start this lamp must be OFF - not light.
If you have message on display LOW OIL PRESSURE and motor running then there is a problem and first check is if enough motor oil and if oil pressure sensor is ok.

update: engine dont start,
I turned on the diagnostics machine and there is a permanent error in the ECU that does not delete it, this error is blocking the motor, so I can not advance to solve the problem. I already changed the oil the sensor is good and the pump also.I think it's the fiat machine and it manages to erase the error because it has already tried other diagnostic machines and none can even enter the engine ECU.

What error code ?

 

[ruicordeiro1]

the car is already in the fiat, they say that there is an error in the ECU and that the solution is to change the ECU. Is it not possible to delete and install new software? The ECU has no repair? There is no other technique / machine that erases the error? I put these questions and said that it has to be a new central unit. It seems they are going for the quickest and simplest solution but, it is the most expensive for me. Anyone have an opinion or suggestion?

the fiat dont no what means that error. they call another fiat technician specialied in ecu,to check the ecu error, and trie solve the problem.
