P0054 2006 Ford Fusion Code - HO2S Heater Resistance Bank 1 Sensor 2

Quick Answer

The Heated Oxygen Sensor (HO2S) must reach the operating temperature to provide an accurate voltage signal. Common causes include Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2, Heated Oxygen Sensor Bank 1 Sensor 2 harness is open or shorted, Heated Oxygen Sensor Bank 1 Sensor 2 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 P0054 2006 Ford Fusion Description

The Heated Oxygen Sensor (HO2S) must reach the operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensor to reach operating temperature. With the engine running, the ground is provided to the heater by the HO2S heater low control circuit through a low side driver within the Powertrain Control Module (PCM). The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM determines the temperature by measuring the current flow through the heater. When the heater is in the ON state, the PCM will pulse the heater OFF for 50 ms, once per second. The PCM calculates the heater resistance on a cold start. The Diagnostic Trouble Code (DTC) will set if the heater current requirements too low or high in the HO2S heater control circuit.
