    Hello, the car, as in the topic, I got no response to the gas pedal, I replaced the gas potentiometer, the same thing. Autocom showed errors that cannot be erased P1614 sensor power supply P0190 fuel pressure sensor circuit P0121 accelerator pedal signal 1 P0221 accelerator pedal signal 2 P0100 flowmeter P0180 The fuel temperature sensor. I checked the installation of the transition from sensors to the controller, checked the sensor power supply ok. I accidentally disconnected the flow meter, the car began to react to gas, but only up to 2,000 revolutions, the flow meter was returned. I also noticed that when I unplug the fuel pressure sensor on the rail and the fishnet is connected, the xsara also reacts to gas, but the same as on the disconnected fishnet only up to 2,000. The next suggestion is that when I disconnect the fishnet or the sensor, I can delete the errors, only one P0190 remains. Unfortunately, I will have the sensor on Monday.

    Short circuit on any of the sensors or its power supply and then the controller disconnects the voltage on some circuits
