INJECTORSN14QTAGCHECKING OPERATION SOUND
Using a sound-scope, check the operation sound (“chi-chi-chi”)of injectors during idling or during cranking.
Check that as the rotating speed increases, the frequency of
the operating sound also increases.
Caution
Note that even if the injector you are checking is not
operating, you will hear the operating sound of the other
injectors.
NOTEIf no operating sound is heard from the injector that is being
checked, check the injector drive circuit. If there is nothing
wrong with the circuit, a defective injector or engine control
unit is suspected.
MEASURING RESISTANCE BETWEEN TERMINALS
(1) Remove the injector connector.
(2) Measure the resistance between the terminals.
Standard value: 13
- 16 L(Z [at 20°C (68”F)I(3) Install the injector connector.
IDLE SPEED CONTROL SERVO
INSPECTION
NlQQUAAb(1) Disconnect the idle speed control servo connector.
(2) Check continuity of the idle speed control servo coil.
