B11E7 (15-08) — Air Distribution Damper Position Sensor – Circuit Short to Battery or Open

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B11E7

B11E7 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B11E7 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B11E7 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Heating, Ventilation and Air Conditioning (HVAC) control module monitors the air distribution damper position sensor to verify that the damper door actually moves to the position commanded by the climate control system. The air distribution damper routes conditioned air between the face, foot, and demist outlets, and is driven by a small electric stepper or DC motor that includes a built in potentiometer style position sensor. The HVAC module supplies a reference voltage (typically 5V) to the sensor, and reads back a varying signal voltage that corresponds to the mechanical position of the...
