Injector Balance Test

An injector balance test is performed with scan tool. This test will properly identify a stuck closed or noisy injector nozzle. Typically, a nozzle failure will fall into this criteria.

1. Install scan tool.
2. Start and idle engine.
3. Perform injector balance test on each cylinder. If a suspect nozzle has been located, nozzle can be swapped with adjacent cylinder and balance test can be repeated as a check to positively identify a malfunctioning nozzle.
4. Locate and replace malfunctioning nozzle and glow plug.
