P0050 2015 Ford F150 Code - HO2S Heater Control Circuit Bank 2 Sensor 1

Quick Answer

The universal HO2S, sometimes referred to as a wideband oxygen sensor, uses the typical HO2S combined with a current controller in the Powertrain Control Module (PCM) to infer an air to fuel ratio relative to the stoichiometric air to fuel ratio. Common causes include Faulty Universal Heated Oxygen Sensor Bank 2 Sensor 1 (HO2S21), Universal Heated Oxygen Sensor Bank 2 Sensor 1 circuit open shorted to ground, Universal Heated Oxygen Sensor Bank 2 Sensor 1 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.

What it means: P0050 2015 Ford F150 indicates HO2S Heater Control Circuit Bank 2 Sensor 1.
Common causes: Common causes include Faulty Universal Heated Oxygen Sensor Bank 2 Sensor 1 (HO2S21), Universal Heated Oxygen Sensor Bank 2 Sensor 1 circuit open shorted to ground, Universal Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection.

Code P0050 2015 Ford F150 Description

The universal HO2S, sometimes referred to as a wideband oxygen sensor, uses the typical HO2S combined with a current controller in the Powertrain Control Module (PCM) to infer an air to fuel ratio relative to the stoichiometric air to fuel ratio. This is accomplished by balancing the amount of oxygen ions pumped in or out of a measurement chamber within the sensor. The typical HO2S within the universal HO2S detects the oxygen content of the exhaust gas in the measurement chamber. The oxygen content inside the measurement chamber is maintained at the stoichiometric air to fuel ratio by pumping oxygen ions in and out of the measurement chamber. As the exhaust gasses get richer or leaner, the amount of oxygen that must be pumped in or out to maintain a stoichiometric air to fuel ratio in the measurement chamber varies in proportion to the air to fuel ratio. The amount of current required to pump the oxygen ions in or out of the measurement chamber is used to measure the air to fuel ratio. The measured air to fuel ratio is actually the output from the current controller in the PCM and not a signal that comes directly from the sensor.
The universal HO2S also uses a self contained reference chamber to make sure an oxygen differential is always present. The oxygen for the reference chamber is supplied by pumping small amounts of oxygen ions from the measurement chamber into the reference chamber. The universal HO2S does not need access to outside air.
Part to part variance is compensated for by placing a resistor in the connector. This resistor trims the current measured by the current controller in the PCM.
The universal HO2S heater is embedded with the sensing element allowing the engine to enter closed loop operation sooner. The heating element heats the sensor to a temperature of 780°C to 830°C (1,436°F to 1,526°F).
The PCM controls the universal Heated Oxygen Sensor Bank 2, Sensor 1 (HO2S21) 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.
