How do I fix error code P228D chevy malibu?
Error code P228D is a common issue that Chevy Malibu owners may encounter. This code indicates a problem with the fuel pressure regulator, specifically that the fuel pressure is too high. Left unresolved, it can lead to poor engine performance or even damage. In this article, we’ll walk you through the steps to diagnose and fix this issue, ensuring your Malibu runs smoothly again.
What Does Error Code P228D Mean?
Error code P228D is triggered when the engine control module (ECM) detects that the fuel pressure in the high-pressure fuel system is higher than the expected range. This can be caused by a malfunctioning fuel pressure regulator, a faulty fuel pump, or issues with the fuel injectors. Symptoms of this error code may include:
- Check Engine Light illuminated on the dashboard.
- Rough idling or stalling.
- Reduced fuel efficiency.
- Difficulty starting the engine.
Steps to Fix Error Code P228D
Follow these steps to diagnose and resolve the issue:
- Step 1: Scan for Error Codes
Use an OBD-II scanner to confirm the P228D code. This will also help identify any additional codes that might be related to the issue.
- Step 2: Inspect the Fuel Pressure Sensor
Check the fuel pressure sensor for any visible damage or loose connections. A faulty sensor can send incorrect readings to the ECM, triggering the error code.
- Step 3: Test the Fuel Pressure
Use a fuel pressure gauge to measure the pressure in the fuel system. Compare the readings to the manufacturer’s specifications for your Chevy Malibu. If the pressure is too high, the fuel pressure regulator or fuel pump may be at fault.
- Step 4: Inspect the Fuel Pressure Regulator
Remove and inspect the fuel pressure regulator for signs of wear or damage. Replace it if necessary. This is a common culprit for error code P228D.
- Step 5: Check the Fuel Pump
If the fuel pressure regulator is functioning correctly, test the fuel pump. A malfunctioning pump can cause excessive pressure in the fuel system.
- Step 6: Inspect the Fuel Injectors
Clogged or damaged fuel injectors can also contribute to high fuel pressure. Clean or replace them as needed.
- Step 7: Clear the Error Code
After addressing the issue, use the OBD-II scanner to clear the error code. Start the engine and monitor its performance to ensure the problem is resolved.

Frequently Asked Questions
What is the difference between a fuel pump and a high pressure fuel pump?
In simple terms, a high pressure fuel pump is a device that delivers fuel to the engine at a significantly higher pressure than regular fuel pumps. Its purpose is to ensure that the engine receives the right amount of fuel with the necessary pressure for combustion.
What causes a fuel pressure regulator to go bad?
That can be caused by any number of things, but it's usually debris in the fuel causing a small tear of some kind or a fuel additive that is not compatible with the diaphragm material.
Where is the fuel pressure regulator located?
The fuel pressure regulator can typically be found at one end of the fuel rail in systems that include a return feed for fuel. In returnless systems, the regulator is integrated in the fuel tank near to the pump so that it is easier to access.
What happens if you drive on a bad fuel pressure regulator?
A faulty fuel pressure regulator can cause a loss of fuel pressure. As a result, the engine may exhibit performance problems, such as hard-starting, rough running, stalling, and a lack of power.
What is the code P228D on a 2013 Chevy Malibu?
The trouble code P228D can be elucidated as Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too High. This error code would start appearing when a high voltage signal from the control circuit of the electronic fuel pressure regulator would be detected by the powertrain control module.
What is the fuel pressure regulator exceeded?
The definition of code P228F is “Fuel Pressure Regulator A – Exceeded Learning Limits – Too High,” sometimes also referred to the regulator as “Fuel Pressure Regulator 1.” This code indicates that your vehicle's powertrain control module (PCM) or engine control module (ECM) has identified an issue with your electronic ...
What is the code P228D on a 2016 Chevy Malibu?
The P228D code can happen for a variety of reasons. It may be that your engine is incorrectly timed, in which case you might need expert assistance to fix the timing on various components. Low engine oil pressure can also be the cause of this code. Consider checking your oil level to see whether you need to top it off.
How to fix a P228D code?
If you want to fix this trouble code, you must determine the faulty parts that triggered the code and replace or repair them as needed. It could be anything from a bad fuel pressure sensor to a malfunctioning fuel pressure regulator.
What is the code for a bad fuel pressure regulator?
P0089
The P0089 code indicates a possible issue with the fuel pressure in your vehicle. The base of the problem is that the fuel pressure sensor is showing a fuel rail pressure that is distinctly different from the desired fuel pressure.
What is the code p228?
Common causes of the P228C code are a bad high-pressure fuel pump, failed low-pressure fuel pump failure, and a faulty fuel pressure sensor. A vehicle that sets a P228C code can show symptoms like the engine failing to start, stalling, and performing poorly.
