DTC P0894 Transmission Component Slipping; DTC P2714 Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT): Description
WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the duty ratio* of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.
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
DTC DETECTION CONDITION AND TROUBLE AREA
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0894 | ECM detects a malfunction on SLT, S1, S2, SR, SL1, SL2 or 1-2 shift solenoid valve according to the revolution difference of the turbine and the output shaft, and also by the oil pressure. (2-trip detection logic) |
|
| 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) |
