Code P015D 2016 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 HO2S 1 rich-to-lean or lean-to-rich average response time is greater than a calibrated value for greater than 60s.
What are the Possible Causes of the DTC P015D 2016 Chevrolet Silverado?
- Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1
- Heated Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted
- Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
