P2801 - Transmission Range Sensor B Circuit Range/Performance

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

P2801 - TRANSMISSION RANGE SENSOR B CIRCUIT RANGE/PERFORMANCE

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 two or more TR signals are low or high.
Possible Causes:	TR circuits shorted to ground or SIG RTN TR circuits shorted to voltage or VREF TR circuits open Two TR VREF circuits open Two TR SIG RTN circuits open Two TR VREF circuits shorted to ground or SIG RTN Damaged TR sensor.
Diagnostic Aids:	See the diagnostic aids for DTC P2800 .
