|P0190 CHEVROLET code description

The Fuel Rail Pressure (FRP) sensor has a 5-volt reference circuit, a signal circuit, and a low reference circuit. The Engine Control Module (ECM) monitors the voltage on the FRP sensor circuits. When the fuel pressure is high, the signal voltage is high. When the fuel pressure is low, the signal voltage is low. The fuel pressure regulator has a solenoid supply voltage circuit and a solenoid control circuit. The ECM controls the fuel pressure regulator, which regulates high pressure fuel that goes to the fuel injector rails and the injectors.
