P1E0F Code - Blower Fan Speed Signal Short To Ground
Quick Answer
The Powertrain Control Module receives a CAN BUS message from the Heating, Ventilation, and Air Conditioning (HVAC) module that the blower speed signal circuit is shorted to ground. Common causes include Faulty Heating, Ventilation, and Air Conditioning (HVAC) Blower Fan, Heating, Ventilation, and Air Conditioning (HVAC) harness is open or shorted, Heating, Ventilation, and Air Conditioning (HVAC) 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.
