P275BTransmission Fluid Temperature Sensor D Circuit Range/Performance

P275B indicates that the transmission control module has detected an out-of-range or performance problem with the circuit for transmission fluid temperature sensor D, which is one of several temperature sensors used to monitor fluid temperature. The computer compares the sensor's signal against expected values and other temperature sensors, and when the signal falls outside the acceptable range or behaves erratically, it stores this code and may illuminate the warning light.
