B11F0 Mercury Code - Air Intake Damper Position Sensor Circuit
Quick Answer
The Heating, Ventilation, and Air Conditioning (HVAC) Module supplies ground to the air inlet door actuator motor through the recirc open circuit to rotate the air inlet door actuator 180 degrees to the outside air position, or the recirc close circuit to rotate the air inlet door actuator another 180 degrees to the recirculated air position. Common causes include Faulty Air Intake Damper Position Sensor, Air Intake Damper Position Sensor harness is open or shorted, Air Intake Damper Position Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
