What does code P2802 mean?

Q: What does code P2802 mean?

Transmission Range Sensor B Circuit Low. P2802 indicates that the transmission control module has detected a low-voltage condition on the signal circuit for Transmission Range Sensor B, which is often the output speed or range confirmation sensor inside the transmission. The computer expects a voltage signal within a specific range, and a value below the threshold means the circuit is shorted to ground, has excessive resistance, or the sensor itself has failed.
