P2800Transmission Range Sensor B Circuit (PRNDL Input)

P2800 indicates that the transmission control module has detected an implausible or missing signal from the transmission range sensor, also known as the PRNDL (Park, Reverse, Neutral, Drive, Low) input, for circuit B. The computer compares the expected gear position from the sensor against other inputs and sets this code when the voltage or signal does not match the commanded range.
