AUTOMATIC TRANSAXLE SYSTEM, 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 and NC), 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 and NC), the ECM calculates the heat level of the friction material, and detects clutch slippage, etc.

SAE Code:

P2714

MONITOR DESCRIPTION

The ECM calculates the amount of heat absorbed by the clutch discs and brake discs based on the difference in speed (clutch slippage) between the turbine (input) and output shaft. If the amount of heat absorption exceeds the specified value, the ECM will illuminate the MIL and store this DTC.

If the solenoid (SLT) valve is stuck ON, the line pressure and clutch engagement force will decrease.

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 transaxle are replaced.
