Code P0090 2016 Chevrolet Silverado Description

High-pressure fuel is regulated by the high-pressure fuel pump actuator, which is a part of the High-Pressure Fuel Pump. The high-pressure fuel pump actuator is a solenoid valve. The Engine Control Module (ECM) provides battery voltage on the actuator high control circuit and ground on the actuator low control circuit. Both circuits are controlled through output drivers within the ECM. When deactivated, both drivers are disabled. When activated, the high control circuit driver energizes the high-pressure fuel pump actuator, and the low control circuit driver Pulse-Width Modulates (PWM) the low control circuit to the ground. The ECM monitors the voltage on the circuits to detect a failure. The Diagnostic Trouble Code (DTC) will set if the ECM detects an open circuit in the high-pressure fuel pump actuator low control circuit.
