P228D 2016 GMC Sierra Code - Fuel Pressure Regulator Control Performance High Pressure
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 P228D 2016 GMC Sierra 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 actual fuel rail pressure is 3 MPa (435 psi) greater than the desired fuel rail pressure. The condition exists for greater than 5 s.
What are the Possible Causes of the DTC P228D 2016 GMC Sierra?
- Faulty Fuel Rail Pressure Sensor

Frequently Asked Questions about P228D 2016 GMC Sierra Code
What does the OBDII code P228D mean on a 2016 GMC Sierra?
1. P228D indicates a "Fuel Pressure Regulator Control Performance High Pressure" issue, meaning the fuel pressure in the high-pressure system is outside the expected range. 2.
What are the common symptoms of a P228D code on a 2016 GMC Sierra?
Symptoms include poor engine performance, rough idling, reduced fuel efficiency, hard starting, stalling, or the Check Engine Light being illuminated. 3.
What causes the P228D code to appear on a 2016 GMC Sierra?
Common causes include a faulty high-pressure fuel pump, a malfunctioning fuel pressure regulator, clogged fuel injectors, or wiring/connector issues in the fuel pressure control circuit. 4.
Can I drive my 2016 GMC Sierra with a P228D code?
Driving with this code is not recommended as it can lead to engine damage, poor performance, or unsafe driving conditions due to stalling or lack of power. 5.
How is the P228D code diagnosed on a 2016 GMC Sierra?
A mechanic will use a scan tool to confirm the code, inspect the fuel pressure sensor and regulator, check for wiring or connector issues, and measure actual vs. desired fuel pressure. 6.
What repairs fix the P228D code on a 2016 GMC Sierra?
Repairs may include replacing the high-pressure fuel pump, fuel pressure regulator, or fuel injectors, and repairing or replacing damaged wiring or connectors. 7.
Does a dirty fuel filter cause the P228D code on a 2016 GMC Sierra?
While not directly causing the code, a clogged fuel filter can restrict fuel flow, which may contribute to pressure irregularities and lead to this issue. 8.
How much does it cost to fix a P228D code on a 2016 GMC Sierra?
Repair costs vary widely depending on the issue, but replacing a high-pressure fuel pump can range from $500 to $1,500, while simpler fixes like wiring repairs may cost less. 9.
How can I prevent a P228D code from occurring on a 2016 GMC Sierra?
Regular maintenance, such as replacing the fuel filter, using quality fuel, and inspecting the fuel system components periodically, can help prevent this issue. 10.
Can a faulty fuel pressure sensor cause the P228D code on a 2016 GMC Sierra?
Yes, a malfunctioning fuel pressure sensor can send incorrect signals to the ECU, leading to a P228D code.
