This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that the pressure of the fuel going to the engine is too low on one side of the engine. It's like trying to drink a milkshake through a straw that's too thin.
This code indicates that the fuel pressure in the rail, which supplies fuel to the engine injectors, is lower than expected after the engine starts injecting fuel, specifically on Bank 2.
The fuel rail pressure sensor monitors the pressure of the fuel in the rail. If the pressure is too low, it can cause poor engine performance or failure to start. Bank 2 refers to the side of the engine opposite Bank 1 in a V-type engine configuration.
• Engine misfires
• Poor acceleration
• Check engine light is on
• Faulty fuel pump
• Clogged fuel filter
• Fuel pressure sensor malfunction
Fuel Rail: A pipe that delivers fuel to the engine's injectors.
Bank 2: The side of a V-type engine opposite Bank 1.
• Check fuel pressure with a gauge
• Inspect fuel lines for leaks or blockages
• Test the fuel pressure sensor
• Replace faulty fuel pump
• Clean or replace fuel filter

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly replace fuel filter
• Use high-quality fuel

Engine Performance
• Avoid driving with low fuel levels
• Schedule regular maintenance
• Use recommended fuel type
Check with your vehicle manufacturer for warranty coverage on fuel system components.
This code is commonly reported in vehicles with high mileage or those that have not been regularly maintained.
Moderate – It's important to address this issue to avoid further engine performance problems.
Driving with this issue can lead to increased emissions and reduced fuel efficiency.
• Engine at operating temperature
• Vehicle in park or neutral
The fuel rail pressure sensor is typically located on the fuel rail on the engine.
Q: Can I drive with a P3054 code?
A: It's not recommended as it can lead to poor engine performance and increased emissions.
Q: How do I fix a P3054 code?
A: You may need to replace the fuel pump, clean or replace the fuel filter, or replace the fuel pressure sensor.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
