What Fuel Injector Cleaner Does Toyota Recommend?

Last Updated on October 6, 2023 by Matthew Lloyd

Toyota recommends using its pressurized fuel injector cleaner to address drivability issues caused by carbon deposits in the fuel injectors and combustion chambers. The fuel injector cleaner helps improve performance, enhance fuel economy, and reduce emissions. It is available in two sizes based on the engine type. To use the cleaner, you connect the tool, start the engine, run it until it stalls, and perform final checks. For Scion FR-S and hybrid vehicles, there are slightly different procedures. Toyota’s pressurized fuel injector cleaner is an effective solution for maintaining optimal engine performance and efficiency.

Benefits of Toyota Injector Cleaner

Toyota’s pressurized fuel injector cleaner offers several advantages for your vehicle, including:

1. Improved Performance: Carbon deposits can affect the fine fuel spray pattern needed for proper atomization and combustion over time. You can use Toyota’s fuel injector cleaner to restore the optimal spray pattern, leading to smoother engine performance and reduced drivability issues such as stalling and hesitation.
2. Enhanced Fuel Economy: When carbon deposits affect fuel atomization, the engine’s efficiency is compromised, increasing fuel consumption. By cleaning the fuel injectors and combustion chambers, Toyota’s injector cleaner helps restore fuel efficiency, allowing you to get the most out of each fuel tank.
3. Reduced Emissions: Carbon deposits in the combustion chambers can contribute to harmful emissions. Toyota’s fuel injector cleaner helps remove these deposits, leading to cleaner combustion and lower emissions.
4. Quick and Effective Deposit Removal: Toyota’s pressurized fuel injector cleaner is designed to quickly and efficiently remove even the toughest carbon deposits from the fuel injectors, intake valves, and combustion chambers. This ensures thorough cleaning and helps restore optimal engine performance.

Toyota’s Recommended Fuel Injector Cleaner Options

Toyota offers pressurized fuel injector cleaner in two sizes, depending on your vehicle’s engine type:

1. For Four or Six-Cylinder Engines: A 7-ounce can of solvent is recommended.
2. For Eight-Cylinder Engines: A 14-ounce can of solvent is recommended.

To perform the fuel injector cleaning service, you will need the EFI device with a hanger and adapter pack, which contains all the necessary tools and adapters for the procedure.

How to Use Toyota’s Pressurized Fuel Injector Cleaner

Performing the fuel injector cleaning service with Toyota’s pressurized fuel injector cleaner involves the following steps:

Preparation:

• Ensure the vehicle’s oil level is full before starting the service. Determine whether the vehicle has a return or returnless fuel delivery system. Refer to the EFI system service technician job aid for assistance.

Test Drive:

• Take the vehicle for a test drive to bring the engine up to operating temperature and evaluate its general condition.

Connecting the Tool:

• For return-type systems: Use the recirculation adapter from the kit to connect the fuel pump output line to the fuel return line leading to the tank.
• Select the appropriate adapter for returnless systems to block off the fuel pump supply line.
• Hang the tool from a central location on the hood, ensuring the handle is off.
• Carefully screw the can of Toyota’s pressurized fuel injector cleaner onto the EFI tool.

Connecting Fuel Lines:

• Connect the EFI tool to the fuel rail feed line.
• Set the EFI tool’s valve to the open position.
• Check all connections thoroughly for leaks.

Starting the Engine:

• Start the engine and check for leaks at the connections.
• If the engine has trouble starting, push the accelerator wide open while cranking the ignition to expel any excess air from the system.

Running the Engine:

• Let the engine idle until it stalls (approximately 7-10 minutes for larger engines and 10-15 minutes for smaller engines).
• Close the tool valve and carefully remove the EFI can using a shop rag to absorb excess fluid.

Disconnecting the Tool:

• Disconnect all tool connections and reconnect the factory lines.
• Replace any gaskets or seals as necessary.
• Reconnect fuel pump relays and connections if they were disconnected during the service.

Final Checks:

• Pressurize the fuel system and check for leaks.
• Start the engine and idle the vehicle for 4-5 minutes.
• Take another test drive to ensure everything is running smoothly.

Toyota Fuel Injector Cleaner for Scion FR-S and Hybrid Vehicles

The fuel injector cleaning procedure differs slightly for Scion FR-S and hybrid vehicles. Here’s an overview:

• Scion FR-S: Follow the same steps as above but note that the Scion FR-S uses a direct and port injection system. You’ll need to run the fuel injector cleaner through the line feeding the stepper pump and the rail injectors.
• Hybrid Vehicles: Hybrid vehicles must be in inspection mode to start the engine. Refer to the shop manual for the specific procedure.

Conclusion

Toyota’s pressurized fuel injector cleaner effectively addresses drivability issues caused by carbon deposits in the fuel injectors and combustion chambers. This recommended cleaner can experience improved performance, fuel economy, and reduced emissions. Toyota’s commitment to providing efficient and reliable products extends to their fuel system maintenance solutions, ensuring your vehicle operates at its best. Don’t let carbon deposits hinder your driving experience. Give your Toyota vehicle the care it deserves with Toyota’s recommended fuel injector cleaner.
