P2719Pressure Control Solenoid D Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2719 means the electrical readings on the control circuit of solenoid D are implausible, although neither a clear open nor a clear short is present. In GM's 2016 table 16OBDG03 the T76 six-speed flags it when the hardware layer reports an invalid voltage in at least 4.4 of 5 seconds; valve D is the 2-6 brake there, and the code is listed without MIL. Bulletin PI0893 matches this for the 2013 6T70/6T75 in Enclave, SRX, XTS, Equinox, Malibu, Traverse, Acadia and Terrain: P2719, P2728 and P0965 are Type C codes that may be stored falsely at fluid temperatures from -0.5 to 0 °C in Park or Neutral, cause no drivability issue and need no parts. Only if the code stays active above 0 °C is normal circuit diagnosis due.
