Code P013B 2015 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 accumulated mass airflow monitored during lean-to-rich transitions between 350 - 650 mV is greater than calibrated value.
What are the Possible Causes of the DTC P013B 2015 Chevrolet Silverado?
- Faulty Heated Oxygen Bank 1 Sensor 2
- Heated Oxygen Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Bank 1 Sensor 2 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
How to Fix the DTC P013B 2015 Chevrolet Silverado?
