P1489 2007 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.

Code P1489 2007 Ford Fusion Description

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. When the intake air temperature exceeds 9°C (48°F) the heater is turned OFF. The PCV Heater is also off when the engine is not running to prevent unnecessary battery drain. The heater is also off if the vehicle charging system is greater than 16 volts. This minimizes heater element overload.
The Diagnostic Trouble Code (DTC) sets when the PCM detects the actual PCVHC circuit voltage is less than or greater than the desired voltage.
