ON?VEHICLE INSPECTION 1. INSPECT INJECTOR OPERATION Check operation sound from each injector. (a) With the engine running or cranking, use a sound scope to check that there is normal operating noise in proportion to engine rpm. (b) If you have no sound scope, you can check the injector transmission operation with your finger. If no sound or unusual sound is heard, check the wiring connector, injector or injection signal from the ECU. 2. INSPECT INJECTOR RESISTANCE (a) Disconnect the injector connector. (b) Using an ohmmeter, measure the resistance between the terminals. Resistance: Approx. 13.8W If the resistance is not as specified, replace the injector. (c) Reconnect the injector connector.
