  P2716  Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

Shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and vehicle speed sensor. The ECM adjusts the current to shift solenoid valve SLT to control the hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.

DTC Code
DTC Detection Condition
Trouble Area
P2716
Open or short is detected in the shift solenoid valve SLT circuit for 1 sec. or more while driving (1-trip detection logic).
  1. Open or short in shift solenoid valve SLT circuit
  2. Shift solenoid valve SLT
  3. ECM

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.
