Purpose/Function
The torque converter clutch (TCC) control solenoid adjusts the hydraulic pressure in the TCC control circuit based on the current demand from the TCM according to the vehicle conditions.
Construction
The TCC control solenoid is installed to the solenoid control body.
The TCC control solenoid is a normal closed-type linear solenoid.
Operation
Adjusts the TCC control clutch pressure by increasing/decreasing the energization current to the TCC control solenoid according to the signal from the TCM.
Air Fuel Ratio (A/F) Sensor Heater Control
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.

Oil Pressure Inspection
WARNING:
Hot engines and engine oil can cause severe burns. Turn off the engine and
wait until it and the engine oil have cooled.
A vehicle that is lifted but not securely supported on safety stands is dangerous.
It can slip or fall, causing death or serious injury. Never work ...
Engine Oil Solenoid Valve
Purpose, Function
The engine oil solenoid valve switches the hydraulic transmission passage
in accordance with the driving conditions and the oil pump drive resistance
is reduced by controlling oil pump discharging pressure in two steps.
Construction
The engine oil solenoid ...
