Condition
Some customers may comment on the following conditions:
• Reduced engine power
• Reduced Engine Power message displayed on DIC
• MIL illuminated
Some customers may also comment that the MIL and Reduced Engine Power message
displayed clears after cycling the ignition key.
Some technicians may find DTC P228C (Fuel Pressure Regulator Control Performance Low Pressure) has set again in the Engine Control Module (ECM) as current or history.
Some technicians may also find a prior repair of the high-pressure fuel pump.
Cause
This condition may be caused by excessive use of E85, causing a plunger internal to the
fuel pump to stick.
Correction
Note: To help keep the engine running efficiently, fill the tank with gasoline, up to E15,
after filling the tank with E85 one or two times.
If the code is set, proceed with the Service Procedure below.
Service Procedure
Parts Information
1. Take a large fuel sample from the fuel system in a
clean glass or metal container.
2. Inspect for any contaminants in the fuel.
⇒ Place the container on a level surface for
approximately 5 minutes in order to allow
settling of the particulate contamination.
3. Verify there are no physical contaminants present
in the fuel sample:
• If contamination is found in the fuel sample,
inspect the fuel tank and strainer for buildup or
blockage then completely clean the fuel system
and add E-10/15 fuel. Refer to Fuel System
Cleaning in SI.
⇒ Contamination in the fuel is not warrantable.
• If contamination is not found in the fuel sample
and/or SI diagnostics leads to a high pressure
fuel pump concern, replace the high-pressure
fuel pump and related lines per SI. Refer to Fuel
Pump Replacement in SI.
Advise the customer to run a tank of premium or Top
Tier E-10/15 fuel (1 tank) through the system to
effectively clean all fuel system components after
repair.
For part numbers of fuel pump lines, refer to the
Electronic Parts Catalog (EPC).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
