Toyota 4Runner: Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

Toyota 4Runner Service Manual / Drivetrain / A750e Automatic Transmission / Transaxle / Automatic Transmission System / Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

DESCRIPTION

Refer to DTC P2714 (See page ).


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).

  • Open or short in shift solenoid valve SLT circuit
  • Shift solenoid valve SLT
  • 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.
