P2716

DTC P2716 Pressure Control Solenoid "D" Electrical (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

P2716:

1. Reference: Inspect using an oscilloscope. Check the waveform of the ECM connector.
OK: Refer to illustration.





MONITOR DESCRIPTION
When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.
