DTC No. DTC Detection Condition Trouble Area
P2759 Open or short is detected in shift solenoid valve SLU circuit for 1 second or more while driving (1-trip detection logic).

  • Open or short in shift solenoid valve SLU circuit

  • Shift solenoid valve SLU

  • TCM

MONITOR DESCRIPTION

When an open or short in a shift solenoid valve (SLU) circuit is detected, the TCM determines there is a malfunction. The TCM will turn on the MIL and store this DTC.
