The AUTOOL CT160 is a 4-cylinder ultrasonic fuel injector cleaner and tester for standard 12V gasoline injectors. It supports ultrasonic cleaning, heated cleaning fluid up to 45°C, leakage test, spray pattern observation, spray volume comparison, and multiple simulated working-condition tests for cars and compatible motorcycles.
Correct fluid selection is critical for CT160. Use cleaning fluid only in the ultrasonic cleaning tank and test fluid only in the injector testing circuit. Using the wrong liquid may damage internal parts.
Use Proper Cleaning Fluid
For ultrasonic cleaning, use professional engine carbon cleaning fluid or injector ultrasonic cleaning fluid. 75%+ medical alcohol can be used as an alternative, but cleaning performance may be weaker.
Use Proper Test Fluid
For injector testing, use professional automotive injector test fluid. If it is not available locally, 75%+ medical alcohol can be used as an alternative test fluid.
Do Not Test With Cleaning Fluid
Do not use corrosive cleaning fluid as test fluid. Cleaning fluid may corrode internal components and rubber parts, cause leaks, and damage the machine.
Do Not Run Ultrasonic Tank Dry
Add the correct cleaning fluid before starting ultrasonic cleaning. Running the ultrasonic function without fluid may damage the ultrasonic motherboard.
Diesel Injector Limit
CT160 can clean diesel injectors with ultrasonic cleaning, but it cannot test diesel injectors. Use CT160 testing functions for compatible gasoline injectors only.
Single Injector Testing
When testing a single injector, plug the other 3 cylinders. CT160 comes with 3 plugs for this single-injector testing setup.
Additional Reminders
CT160 is designed for standard 12V gasoline injectors, not GDI high-pressure injector testing.
For GDI, EFI, FSI, or broader high-pressure injector compatibility, consider CT400, CT450, CT500, FN606, or FN608.
Non-disassembly injector cleaning and throttle valve cleaning require optional accessories and may require extra purchase.
The working voltage range supports 110V or 220V power input. Choose the correct plug and voltage version for your region.
If short-circuit protection is triggered, the internal fuse may shut down the machine to reduce electrical risk. Stop use and check before restarting.

Select options
This product has multiple variants. The options may be chosen on the product page
Contact AUTOOL Store before ordering if you need to confirm cleaning fluid, test fluid, GDI compatibility, diesel injector limits, motorcycle injector accessories, or CT160 package contents.
These answers cover injector compatibility, diesel injector limits, GDI support, fluid selection, model comparison, single injector testing, accessories, and safe operation.
CT160 is designed for cleaning and testing standard 12V gasoline fuel injectors. It supports up to 4 compatible injectors at the same time and can be used for cars and compatible motorcycles when the proper adapters and accessories are used.
CT160 can clean diesel injectors with the ultrasonic cleaning function, but it cannot test diesel injectors. Use the testing functions only for compatible gasoline injectors.
No. CT160 is not recommended for GDI high-pressure injector testing. If you need GDI, EFI, FSI, or broader high-pressure injector compatibility, choose CT400, CT450, CT500, FN606, or FN608 according to the required injector type and testing capacity.
For ultrasonic cleaning, use professional engine carbon cleaning fluid or professional injector ultrasonic cleaning fluid. 75%+ medical alcohol can be used as an alternative if professional cleaning fluid is not available, but the cleaning effect may not be as strong.
For injector testing, use professional automotive injector test fluid. The test fluid should be colorless, odorless, and non-corrosive so it can simulate injector working states without damaging the machine. If professional test fluid is not available, 75%+ medical alcohol can be used as an alternative.
No. Do not use cleaning fluid to test injectors. Cleaning fluid can be corrosive and may damage internal machine components, corrode rubber parts, cause leaks, and lead to repair costs that are not caused by normal machine failure.
When testing a single injector, plug the other 3 cylinder positions. CT160 includes 3 plugs for this setup so the unused cylinders can be blocked during testing.
For basic testing, you do not need complex parameter setup. Select the function number and set the test time according to the test you need. The control panel provides function selection, working parameter display and adjustment, pressure adjustment, and Start / Pause / Stop operation.
CT150 and CT160 are both designed for cleaning and testing fuel injectors of 4-cylinder gasoline engines. The main difference is that CT160 adds an ultrasonic heating function, while CT150 does not have this feature. Compared with CT150, CT200 adds two more testing cylinders for a total of 6, while the other basic functions remain similar.
CT450 adds a Pulse Injection Test compared with CT400. CT500 further adds Wide Pulse Injection Test and Continuous Injection Test compared with CT450. For cleaning and heating, CT450 features ultrasonic cleaning with heating up to 50°C, while CT400 and CT500 do not have the same heating function in this comparison.
FN608 supports testing for 8 cylinders, while FN606 supports testing for 6 cylinders. FN608 also uses two independent fuel pumps, each corresponding to a separate left or right fuel rail. If one pump fails, only the corresponding rail is affected, while the other can continue working. FN606 uses a single fuel pump, so a pump failure stops the whole system until the pump is replaced.
FN608 supports 8 cylinders, while CT500 supports 6 cylinders. FN608 has a heated cleaning tank that can maintain up to 50°C, supports wider voltage ranges including 12V, 12-70V, and 120-180V, and its cleaning tank can be used independently or together with the main unit. CT500 supports 12V, 70V, and 120V, and its cleaning tank is integrated with the main body. FN608 also uses two independent fuel pumps, while CT500 uses a single fuel pump.

Very pleased
This unit works well on many injectors. I have used it on GM and Ford so far. Very repeatable. After giving each injector multiple pulses to verify, I would say each one gave identical results so there was no worries as to the units quality and effectiveness. Bad injector gave the same PSI rating each time as did the good ones. It does not work on GDI injectors but for the price its a must have tool.
