Specialized equipment is required for testing and cleaning DENSO injectors with the appropriate adapter kits . For some Denso injectors, it might be necessary to use the original Denso adapter cable for proper connection during testing . These tests can check critical parameters like injector flow rate and leak-back volume.

Cleanliness During Servicing cannot be overstated. Any time the fuel system is opened for service, such as during injector replacement or fuel line work, extreme cleanliness is paramount. Dirt introduced during these procedures can immediately compromise the system. Furthermore, inspection and maintenance of high-pressure lines and electrical connections are also crucial .

It is also vital to Address Engine Issues Promptly. Symptoms like hard starting, rough idling, loss of power, excessive smoke (especially black smoke), or an illuminated check engine light should be diagnosed and repaired promptly. Ignoring these issues can lead to further damage to the injectors and other expensive engine components.

As part of diagnostics, Electrical System Checks are important. The injector's coil resistance should be checked using an ohmmeter. For DENSO G2 injectors, for example, the normal resistance range is typically very low, around 0.5~0.7 milliohms . Verifying this value can help identify electrical faults within the injector's solenoid.

Finally, the Prevention of Nozzle Coking and Needle Sticking is a key goal. As highlighted in maintenance literature, regular professional cleaning and inspection of the injector are vital to prevent these issues . This process might involve carefully disassembling and cleaning the injector with clean diesel, and using appropriate, non-damaging tools to clean the nozzle holes and remove carbon deposits from the injector body and needle . This underscores the overarching importance of using clean fuel and adhering to periodic professional servicing schedules.
