AUTOMATIC TRANSMISSION SYSTEM(for 8AR-FTS), Diagnostic DTC:P27137F

DTC Code DTC Name
P27137F Pressure Control Solenoid "D" Actuator Stuck Off

DESCRIPTION

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

MONITOR DESCRIPTION

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

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

Note

If driving continues under these conditions, the clutches will burn out and the vehicle will no longer be drivable.

CAUTION / NOTICE / HINT

Note

Perform registration and/or initialization when parts related to the automatic transmission are replaced.
