The throttle pressure that is applied to the primary regulator valve (which modulates the line pressure) causes

2006 TRANSMISSION A750E Automatic Transaxle - Sequoia the solenoid valve SLT, under electronic control, to precisely modulate and generate the line pressure according to the amount of depression of the accelerator pedal or the engine power output. This controls the line pressure and provides smooth shifting characteristics.

Upon receiving a signal of the throttle valve opening angle, the ECM controls the line pressure by sending a predetermined duty ratio* to the solenoid valve, modulating the line pressure and generating throttle pressure.

HINT:

*: The duty ratio is the ratio of the current ON time (A) to the total of the current ON and OFF time (A + B). Duty Ratio (%) = A / (A + B) x 100

ETECTION CONDITION

DTC No.

DTC Detection Condition

Trouble Area

• Shift solenoid valve SLT

remains open or closed

P2714

ECM detects a malfunction on SLT (ON side) according to the revolution difference of the turbine and the output shaft, and also by the oil pressure. (2 trip detection logic)

• Shift solenoid valve S1, S2, SR, SL1 or SL2 remains open or closed

• Valve body is blocked

• Automatic transmission (clutch, brake or gear, etc.)

monitor description

The ECM calculates the amount of heat absorbed by the friction material based on the difference in revolution (clutch slippage) between the turbine and output shaft. The ECM illuminates the MIL and outputs this DTC when the amount of heat absorption exceeds the specified value.

When the shift solenoid valve SLT remains ON, oil pressure goes down and clutch engagement force decreases.
