DTC P0894 Transmission Component Slipping

DTC P2714 Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)

DESCRIPTION





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

P0894/P2714:

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.

NOTICE: If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be drivable.
