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

DESCRIPTION
Based on signals from the accelerator position sensor and speed sensor (NC3, SP2 and NT), the TCM controls the solenoid valve (SLT) to the predetermined duty ratio*. As a result, the line pressure is adjusted to a pressure that is appropriate for the throttle angle and engine output. Based on the transmission revolution sensor (NT, NC3 and SP2) rotation speed, the TCM calculates the heat level of the friction material, and detects the slip condition of the clutch, etc.

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

P2714:

MONITOR DESCRIPTION
The TCM 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 TCM 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.
