Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)
|
DESCRIPTION
Refer to DTC P0894
.
|
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
-
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.
