P0089 2016 Chevrolet Silverado Code - Fuel Pressure Control Performance
Quick Answer
The fuel rail pressure sensor detects fuel pressure within the fuel rail. Common causes include Faulty Fuel Rail Pressure Sensor, High Pressure Fuel Pump harness is open or shorted, High Pressure Fuel Pump electrical circuit poor connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0089 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 ECM provides a 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 ground.
The high-pressure mechanical fuel pump is driven by three lobes on the camshaft. The ECM uses the camshaft and crankshaft position sensor inputs to synchronize the high-pressure fuel pump actuator with the position of each of the camshaft lobes. The ECM regulates fuel pressure by adjusting the portion of each pump stroke that provides fuel to the rail.
The ECM monitors the fuel rail fuel pressure sensor and the high-pressure fuel pump actuator to determine if the commanded and actual pressure are within a predetermined range, or if the amount of fuel pressure correction exceeds a calibrated pressure.
The Diagnostic Trouble Code (DTC) will set if the high-pressure fuel pump actuator command is greater than or equal to 240 degrees or less than or equal to 0 degrees. The condition exists for greater than 5 s.
