What does code P2842 mean?

Q: What does code P2842 mean?

Shift Fork D Position Circuit Low. P2842 is a generic powertrain code indicating that the transmission control module (TCM) has detected a low voltage condition on the electrical circuit for the shift fork D position sensor. This sensor reports the physical engagement position of shift fork D inside the transmission, and a low signal typically means the TCM sees voltage below the expected range, which can prevent reliable gear engagement.
