Title: U660F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P2716; Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT); 2016 MY Sienna [12/2015 - 08/2016]

DTC

P2716

Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

DESCRIPTION

Refer to DTC P2714 (See page 2016 MY Sienna [12/2015 - 08/2016]; U660F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P2714; Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)+ ).

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
  • Transmission wire
  • 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.
