CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2716

DTC Code DTC Name
P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

DESCRIPTION

The ECM uses signals to control shift solenoid valve SLT to provide optimum line pressure control. Shift solenoid valve SLT is also used during forward and reverse clutch engagement to control the oil pressure to the forward and reverse clutch.

DTC No.
