Caution Check carefully. Other injectors may produce sound as they operate even if the injector under checking does not operate.



Resistance between Terminals Measurement

(1) Disconnect the injector connector.
(2) Measure resistance between terminals.

Standard value: 2 - 3 Ohms [at 20~C (68~F)]

(3) Install the injector connector.



Injection State Inspection

(1) Remove the air intake pipe.
(2) Disconnect the high tension cable from the ignition coil.



Injector with Black Connector Inspection

(3) Observing through the air inlet of the injection mixer. visually check injection state of the injector with black connector when the ignition switch is set to ST position. Judge the injector as normal unless the injection state is very poor.
(4) Turn the ignition switch to OFF and check the injector nozzle for leaks.

Injector with Blue Connector Inspection

(5) Disconnect the injector harness of the blue connector.
(6) Connect the harness connected to the injector having black connector to the injector having blue connector. Caution Connect the harness with adequate slackness so that undue tension will not act on the harness when the engine is cranked.




(7) Observing through the air inlet of the injection mixer, visually check injection state of the injector with blue connector when the ignition switch is set to ST position. Judge the injector as normal unless the injection state is very poor.
(8) Turn the ignition switch to OFF and check the injector nozzle for leaks.








ISC MOTOR (DC MOTOR) N14QUAA

INSPECTION

(1) Disconnect the ISC motor connector.
(2) Check continuity of the ISC motor coil.

Measuring terminals Continuity

Conductive
(1) - (4) [5 to 11 Ohms resistance at 20~C (68~F)]


(3) Connect 6V DC between terminals (1) and (4) of the ISC motor connector and check that ISC servo operates.

Caution Apply only a 6V DC or lower voltage. Application of higher voltage could cause locking of the servo gears.

(4) If not, replace ISC servo as an assembly.
