Injector Circuit Test

Disconnect all injector harness connectors. Using digital ohmmeter, check resistance across terminals of each injector. Ohmmeter should read 2.0-2.7 ohms on 1.9L and 2.3L Turbo engines, 16.0-18.0 ohms on 3.0L engines or 15.0-19.0 ohms on 5.0L engines. If not, replace injector.

NOTE: For further component testing and information, see FORD MOTOR CO. ELECTRONIC ENGINE CONTROL IV in COMPUTERIZED ENGINE CONTROL section.
