Injector Balance Test

Injector Balance Test
An injector balance test is performed with the Scan Tool. This test will properly identify a stuck closed or a noisy injector nozzle. Typically, a nozzle failure will fall into this criteria.

1. Install the Scan Tool.
2. Start the engine.
3. Allow the engine to idle.
4. Perform the injector balance test on each cylinder (a balance test refers to a specific cylinder).

NOTE: If a suspect nozzle has been located, the nozzle can be swapped with the adjacent cylinder. The balance test can be repeated as a check in order to positively identify a malfunctioning nozzle.

5. Locate and replace the malfunctioning nozzle and the glow plug.
