P111F BMW Code - Intake Air Temperature Sensor Plausibility

Quick Answer

The Intake Αir Temperature (IΑT) sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). Common causes include Faulty Intake Air Temperature Sensor, Intake Air Temperature Sensor harness is open or shorted, Intake Air Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P111F BMW Description

The Intake Αir Temperature (IΑT) sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases in response to the temperature rise.
