P0056 2015 Ford F150 Code - HO2S Heater Control Circuit Bank 2 Sensor 2
Quick Answer
The HO2S detects the presence of oxygen in the exhaust and produces a variable voltage according to the amount of oxygen detected. Common causes include Faulty Heated Oxygen Sensor Bank 2 Sensor 2 (HO2S22), Heated Oxygen Sensor Bank 2 Sensor 2 circuit open shorted to ground, Heated Oxygen Sensor Bank 2 Sensor 2 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 P0056 2015 Ford F150 Description
When the oxygen sensor is cold, disconnected, or on initial start-up, the voltage may read between 1.5 to 1.7 volts. The oxygen sensor voltage will decrease to the normal operating range of 0.0 to 1.1 volts during warm, stabilized engine running conditions.
The HO2S heater is embedded with a sensing element. The heating element heats the sensor to a temperature of 800°C (1,472°F). At approximately 300°C (572°F) the engine enters closed loop operation. The heater allows the engine to enter closed loop operation sooner.
The PCM controls the Heated Oxygen Sensor Bank 2, Sensor 2 (HO2S22) heater ON and OFF duty cycle to maintain a calibrated temperature. This Diagnostic Trouble Code (DTC) is set when the sensor does not warm up to the required temperature in a calibrated amount of time. This DTC is also set when the PCM is not able to maintain the required temperature after the sensor is warmed.
What are the Possible Causes of the DTC P0056 2015 Ford F150?
- Faulty Heated Oxygen Sensor Bank 2 Sensor 2 (HO2S22)
- Heated Oxygen Sensor Bank 2 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor Bank 2 Sensor 2 circuit poor electrical connection
How to Fix the DTC P0056 2015 Ford F150?
