Error in the engine controller in Citroen C8 2. 0 HDI 2004
Hello mechanics.
Citroen C8 2.0 HDI 2004, The problem is that I have an error in the engine controller P0190. We know what, but we don't know why. Error cannot be cleared. Three pins from the cube have values such as + - and there is 5V when connecting, and 12V on the middle one. The most interesting thing is that by disconnecting the motor controller cubes and checking the pins, the pulse pin is detected in several places, and it should probably be only in one place?

Error P0190 indicates a problem with the fuel pressure sensor or its electrical circuit. This may indicate a sensor failure, damaged wires, or a problem with the plug.
If you measure the voltages on the motor cube, the voltage values depend on the specific sensors and regulators, so without knowing exactly which sensors are responsible for which pins, it is difficult to determine whether the voltage values are correct.
As for the pulse, if it is detected in several places, there may be problems with grounding or electromagnetic interference in the circuit. In this case, it may be necessary to investigate and diagnose the problem more thoroughly by a specialist or a Citroen workshop.
Thank you.
