One treatment petrol injection system is the testing and cleaning injectors. The factors that cause damage to the car injectors Electronic Fuel Injection ( EFI) are clogged 7.0 % , abrasion ( eroded ) 4.2 % , 3.5 % leak , dead solenoid 2.1 % , 17.6 % partially clogged , custody / solenoid resistance down / low 8.4 % , 31.7 % gross , not a good spray pattern and divergence 25.4 % spray pattern. Injector tester and cleaner  is maintenance device in fuel injection system. Disorder in the injector system are  crust, leak and spray pattern divergence. Injector tester currently very expensive on the market. therefore, we have to do innovation for manufacture of test equipment injector cleaner. The Characterization of injector tester were able to measure the accuracy of the number of sprays. Functional testing tool has shown that part of the injector test and cleaning tool has worked well and the test results showed no difficulties in the operation of test equipment. The test results produce an output voltage 9 volts, and the current 5 amperes. Pressure fuel pump 3.3 to 4 bar, within 15 seconds of the 33-46 cc injection volume average of 41.25 cc.Key word: Injector tester, Maintenance, Electronic Fuel Injection (EFI)
