ON−VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is normal operating noise
in proportion to engine speed.
(2) If you have no sound scope, you can check the in-
jector transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Remove the cylinder head cover (See page EM−33).
(b) Disconnect the injector connectors.
(c) Using an ohmmeter, measure the resistance between the
terminals.
Resistance: Approx. 13.8 Ω
If the resistance is not as specified, replace the injector.
(d) Reconnect the injector connectors.
(e) Reinstall the cylinder head cover (See page EM−55).
