Q: What does code P275A mean?

Transmission Fluid Temperature Sensor D Circuit. P275A means the transmission control module (TCM) has detected an abnormal electrical condition on the circuit for transmission fluid temperature sensor D, which is one of several temperature sensors used to monitor fluid heat. The computer compares the sensor's signal against expected values and flags the code when the voltage or resistance falls outside the valid range for a set period.
