DESCRIPTION
The shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the current of the SLT solenoid valve 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 | An open or short is detected in the shift solenoid valve SLT circuit for 1 sec. or more while driving (1 trip detection logic). |
|
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.
