DTC P2800: Transmission Range Sensor B Circuit (PRNDL Input)

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, 2011 Ford Fusion, 2010 Mercury Milan, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
P2800 - TRANSMISSION RANGE SENSOR B CIRCUIT (PRNDL INPUT)

Description:  The powertrain control module (PCM) checks the gear selector position by monitoring two independent voltage signals from the transmission range (TR) sensor. The TR voltages are then compared to an allowed voltage range for each gear. The test fails when the compared voltages are out of range. This DTC indicates that one TR signal is more than one band away from the majority.
Possible Causes: 
  • Two TR circuits shorted together
  • Excessive resistance in one TR circuit
  • Damaged TR Sensor
Diagnostic Aids:  Monitor the TR_A1 and TR_A2 sensor voltage parameter identifiers (PIDs). The TR_A1 sensor voltage has a negative slope, and TR_A2 sensor voltage has a positive slope.
