Purpose/Function
The on/off solenoid performs switching of the shift valve in the control valve body according to the vehicle conditions.
Construction
The on/off solenoid is installed to the solenoid control valve body.
The on/off solenoid is a normal open-type on/off solenoid.

Operation
Non-energization (OFF)
When the on/off solenoid is off, the supply port in the solenoid opens. As a result, hydraulic pressure is supplied to operate the shift valve.
Energized (ON)
When the on/off solenoid is on, the drain port in the solenoid opens. As a result, hydraulic pressure which operates the shift valve is drained.

Outline
Based on the control of the A/F sensor heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
