Diagnostic Procedure (Cont'd)
EC-272

Description
Vibration when stopping the engine can be controlled by cutting
intake air just before the fuel is cut. The intake air control valve
control solenoid valve controls the ON-OFF load of the intake air
control valve actuator. As a result, the intake air control valve con-
trol solenoid valve will be turned ON when the ignition switch is
turned OFF with the engine running and when the engine stalls.
After the engine has stopped, the intake air control valve control
solenoid valve will return to fully open.

ECM Terminals and Reference Value
Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Description
The load from the variable nozzle turbocharger control solenoid
valve controls the actuator. By changing the variable nozzle vane
opening through the rods, the intake air volume is adjusted.
The variable nozzle turbocharger control solenoid valve is moved
by ON/OFF pulse from the ECM. The longer the ON pulse, the
charge air pressure rises.
