DTC codes / P27xx · Transmission / P275E
P275E indicates that the transmission control module (TCM) has detected an intermittent fault in the signal circuit for transmission fluid temperature sensor D, which is one of several temperature sensors used to monitor fluid conditions. The circuit works by sending a voltage signal that varies with temperature, and the TCM flags this code when the signal momentarily drops out or jumps erratically beyond expected limits.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
