Fuel Injector: Testing and Inspection
On-Vehicle Inspection

1. Using sound scope (1) or such, check operating sound of injector when engine is running or cranking.

Cycle of operating sound should vary according to engine speed.
If no sound or an unusual sound is heard, check injector circuit (wire or coupler) or injector.

2. Disconnect coupler from injector, connect ohmmeter between terminals of injector and check resistance.

If resistance is out of specification, replace.

Resistance of injector:
13 - 16 ohm (at 20 °C (68 °F))

3. Connect coupler to injector securely.
