P1489 2006 Ford Fusion Code - PCV Heater Control Circuit Fault
Quick Answer
When the intake air temperature is less than 0°C (32°F) the Powertrain Control Module (PCM) grounds the Positive Crankcase Ventilation Valve Heater Control (PCVHC) circuit and turns the heater ON. Common causes include Faulty Positive Crankcase Ventilation (PCV) Heater, Positive Crankcase Ventilation Heater harness is open or shorted, Positive Crankcase Ventilation Heater circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
