The AUTOOL CT200 injector ultrasonic cleaner and tester is a 6-cylinder fuel injector cleaning and testing machine for standard 12V gasoline fuel injectors. It combines ultrasonic cleaning with microprocessor hydraulic control technology to simulate low, medium, high-speed, acceleration, shifting, leakage, sprayability, reverse flushing, and no-disassembly cleaning workflows. Wide voltage technology supports both 110V and 220V power input.
Before using CT200, confirm the injector type and prepare the correct ultrasonic cleaning fluid and injector test fluid. Cleaning fluid and test fluid must not be mixed or used in the wrong circuit.
Use Professional Cleaning Fluid
For ultrasonic cleaning, use professional engine carbon cleaning fluid or automotive injector ultrasonic cleaning fluid to remove carbon deposits and impurities.
Use Professional Test Fluid
For injector testing, use professional automotive injector test fluid. It is colorless, odorless, and non-corrosive, helping simulate injector working states safely.
Do Not Test With Cleaning Liquid
Do not put corrosive cleaning liquid into the test circuit. It may damage internal components, accelerate rubber deterioration, cause leakage, and create repair costs.
Do Not Run Ultrasonic Cleaning Dry
Add the proper ultrasonic cleaning fluid before running the ultrasonic cleaning function. Running the ultrasonic tank without fluid may damage the ultrasonic motherboard.
75%+ Medical Alcohol Backup
If professional cleaning or test fluid is not available locally, medical alcohol above 75% can be used as a temporary alternative, but the cleaning or test effect may not be ideal.
Five Plugs For Single Injector Test
When testing a single injector, plug the other five cylinder positions. CT200 comes with five plugs for this purpose.
Compatibility Reminder
CT200 is designed for standard 12V gasoline fuel injectors.
CT200 can clean diesel injectors, but it cannot test diesel injectors.
CT200 does not test GDI high-pressure injectors. Choose CT400, CT450, CT500, FN606, or FN608 if you need GDI injector support.
No-disassembly cleaning is an additional function and requires special adapters.
Confirm the fluid type before filling the machine. Cleaning liquid is for ultrasonic cleaning, while test fluid is for the fuel injector testing circuit.

How To Use
How To Use
Use CT200 by cleaning the injector exterior first, running ultrasonic cleaning with the correct cleaning fluid, installing the injectors on the test bench, and then performing leakage, sprayability, flow, and reverse flushing tests with proper test fluid.
Pre-Clean Injector Exterior
Clean the outside of the injectors with suitable gasoline or cleaning liquid before turning on the machine, so loose dirt does not contaminate the cleaning tank or test system.
Add Ultrasonic Cleaning Fluid
Pour the proper ultrasonic cleaning fluid into the cleaning tank, then place the injectors in the ultrasonic bath after the exterior dirt has been removed.
Connect Pulse Signal Wire
Connect the pulse signal wire and select the ultrasonic cleaning function. Ultrasonic vibration helps dislodge particles and carbon buildup inside the injectors.
Install Injectors On Main Unit
Pour in the proper test fluid, install the injectors on the fuel distributor or fuel rail, and fix the assembly to the main unit with bolts.
Run Injector Tests
Run leakage, spray pattern, flow rate, idle, medium, high-speed, acceleration, shifting, and reverse flushing tests according to the selected function number and test time.
Retest And Compare
After cleaning, return the injectors to the flow bench and retest all required functions. Compare spray pattern, measuring tube level, leakage, and flow consistency.
Use Notes
Before or during service, check the injector for resistance, shorts, and current draw if required by your diagnostic workflow.
Select the feature number and set the test time through the control panel. No special parameter setup is required for normal operation.
Use cleaning fluid only in the ultrasonic cleaning tank. Use non-corrosive injector test fluid in the testing system.
For single-injector testing, plug the other five cylinder positions.
No-disassembly cleaning requires special adapters and is not the same as standard bench testing.

CT200 is designed to clean and test standard 12V gasoline fuel injectors. It supports 6-cylinder testing and helps simulate idle, medium speed, high speed, acceleration, shifting, leakage, sprayability, and reverse flushing conditions.
No. CT200 only supports 12V standard fuel injectors for testing. If you need to test GDI high-pressure injectors, choose CT400, CT450, CT500, FN606, or FN608 for better compatibility.
AUTOOL CT series products can clean diesel injectors, but they cannot test diesel injectors. Use CT200 only within its supported testing range.
For ultrasonic cleaning, use professional engine carbon cleaning fluid or professional automotive injector ultrasonic cleaning fluid. It helps remove deposits such as carbon buildup from injectors. If professional cleaning fluid is not available locally, 75%+ medical alcohol may be used as a substitute, but the cleaning effect may vary.
For the intended test effect, use professional automotive injector test fluid. Test fluid is a colorless, odorless, non-corrosive liquid used to assess injector performance and simulate working states. If professional test fluid is not available locally, 75%+ medical alcohol can be used as a temporary alternative.
No. Do not use cleaning liquid in the injector testing circuit. Cleaning liquid may be corrosive and can damage internal parts, accelerate rubber deterioration, cause leakage, and lead to malfunction. Damage caused by using the wrong fluid may require paid repair.
The ultrasonic tank must contain the proper cleaning fluid before the ultrasonic cleaning function is started. Running the ultrasonic system dry or without the proper fluid may damage the ultrasonic motherboard.
When testing a single injector, the other five cylinder positions need to be plugged. CT200 comes with five plugs for single-injector testing or partial injector testing.
You do not need special settings for normal operation. Select the feature number and set the test time through the control panel. The testing process is designed to be straightforward and efficient.
CT200 only supports 12V standard fuel injectors. CT400 supports both 12V standard injectors and GDI injectors, making it compatible with a wider range of injector types and vehicles. CT200 does not have dedicated accessory storage, while CT400 has a drawer for injector adapters and other accessories.
CT150 and CT160 are designed for cleaning and testing fuel injectors of 4-cylinder gasoline engines. CT160 has an ultrasonic heating function, while CT150 does not. Compared with CT150, CT200 mainly adds two more testing cylinders, supporting 6 cylinders in total, while the other functions remain similar.
Compared with CT400, CT450 adds the pulse injection test. Compared with CT450, CT500 further adds wide pulse injection and continuous injection testing. CT450 also has ultrasonic cleaning with heating up to 50°C, while CT400 and CT500 do not have a heating function.
FN608 supports testing for 8 cylinders, while FN606 supports 6 cylinders. FN608 has two independent fuel pumps, each corresponding to a separate left or right fuel rail. If one pump fails, only the corresponding fuel rail is affected, while the other side can continue to operate. FN606 uses a single fuel pump, so a pump failure stops the entire system until the pump is replaced.
FN608 supports 8 cylinders, while CT500 supports 6 cylinders. FN608 has a heating cleaning tank that can maintain up to 50°C, while CT500 does not support heating. FN608 supports 12V, 12-70V, and 120-180V voltage ranges, while CT500 supports 12V, 70V, and 120V. FN608 allows the cleaning tank to operate independently or together with the main unit, while CT500 integrates the cleaning tank into the main body. FN608 also uses two independent fuel pumps, while CT500 uses a single pump.
If you only need to test 12V gasoline fuel injectors, CT160 is a good 4-cylinder choice and CT200 is the 6-cylinder choice. If you need GDI high-pressure injector support, choose CT400, CT450, CT500, FN606, or FN608. If you need heating, CT160, CT450, FN606, and FN608 are stronger options depending on injector type. If you need 8-cylinder testing and dual-pump reliability, choose FN608.
