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

Toyota Venza Service Manual / U660e Automatic Transmission / Transaxle / Automatic Transaxle System / Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

DESCRIPTION

Refer to DTC P2714 (See page ).


DTC No.

DTC Detection Condition

Trouble Area

P2716

Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1-trip detection logic).

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

MONITOR DESCRIPTION

When an open or short in the linear solenoid valve (SLT) circuit is detected, the TCM interprets this as a fault. The TCM will turn on the MIL and store the DTC.
