Code P014A 2014 Chevrolet Silverado Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the O2 sensor voltage has not decreased below 450 mV within a calibrated value of accumulated airflow.
What are the Possible Causes of the DTC P014A 2014 Chevrolet Silverado?
- Faulty Heated Oxygen Bank 2 Sensor 2
- Heated Oxygen Bank 2 Sensor 2 harness is open or shorted
- Heated Oxygen Bank 2 Sensor 2 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
