Fuel Injector on-Vehicle Inspection

Steps 1 - 4:

1. Warm up the engine and let it idle.

2. Listen for operation sound of each fuel injector with a screwdriver or a soundscope.
- If no sound is heard, carry out the "Fuel Injector Resistance Inspection".

NOTE: The best way to judge the performance of a fuel injector is to compare its sound with the sound of other fuel injectors.
