INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
INTAKE AIR CONTROL VALVE CONTROL SOLENOID VALVE
PFP:16188
DescriptionEBS01KM5
Vibration when stopping the engine can be controlled by cutting
intake air right before the fuel is cut. The intake air control valve con-
trol solenoid valve (1) controls the ON-OFF load of the intake air
control valve actuator. As a result, the intake air control valve control
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.
l: Vehicle front
lElectronic controlled engine mount control solenoid valve (2)
lOil filter (3)
ECM Terminals and Reference ValueEBS01KM6
Specification data are reference valves, 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.
