P015D 2015 Chevrolet Silverado Code - Oxygen Sensor Delayed Response Lean to Rich Bank 2 Sensor 1
Quick Answer
The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Common causes include 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. 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 P015D 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 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 2015 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
- Engine vacuum leaks
How to Fix the DTC P015D 2015 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
