INJECTOR
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 is heard or unusual vibration is felt, check the wiring
connector, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the throttle body without disconnecting the
water bypass hoses from the air intake chamber.
(See page SF-42)
(b) Disconnect the 6 injector connectors.
(c) Using an ohmmeter, measure the resistance between the
injector terminals.
Resistance: Approx. 1.95 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(d) Reconnect the 6 injector connectors.
(e) Reinstall the throttle body to the air intake chamber.
