Transmission Solenoid Diagnostics

This document provides troubleshooting steps for resolving a P2716 DTC code related to a pressure control solenoid in the automatic transmission of a vehicle. The steps include inspecting the transmission wire connecting the shift solenoid valve to the ECM for proper resistance values or shorts, checking the harness and connector between the transmission and ECM, and inspecting the shift solenoid valve itself to diagnose whether the valve or connecting components need replacement.

DTC
DESCRIPTION

P2716

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

Refer to DTC P2714 (See page AT-110).


DTC No. P2716 DTC Detection Conditions Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1-trip detection logic) Trouble Areas Open or short in shift solenoid valve SLT circuit Shift solenoid valve SLT ECM

MONITOR DESCRIPTION
When an open or short is detected in the linear solenoid valve (SLT) circuit, the ECM interprets this as a fault. The ECM turns on the MIL and stores the DTC.

MONITOR STRATEGY
Related DTCs Required sensors/Components Frequency of operation Duration MIL operation Sequence of operation P2716: Shift solenoid valve SLT/Range check Shift solenoid valve SLT Continuous 1 second Immediate None

TYPICAL ENABLING CONDITIONS


The monitor will run whenever the following DTCs are not present. Battery voltage CPU requested duty ratio to SLT Ignition switch Starter None 10 V or more Less than 75 % ON OFF

TYPICAL MALFUNCTION THRESHOLDS


Output signal duty 100 %

COMPONENT OPERATING RANGE


Output signal duty ratio Less than 100 %
