P015B NISSAN SENTRA - Air Fuel Ratio Delayed Response - Lean To Rich Bank 1 Sensor 1
P015B NISSAN SENTRA Possible Causes
- Faulty Air Fuel Ratio (A/F) Bank 1 Sensor 1
- Air Fuel Ratio (A/F) Bank 1 Sensor 1 harness is open or shorted
- Air Fuel Ratio (A/F) Bank 1 Sensor 1 circuit poor electrical connection
How is the P015B NISSAN SENTRA code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
There is a Factory Service Bulletin for the following 2011-2012 Nissan Sentra:
2011-2012 Nissan Sentra Factory Service Bulletin OBDII Code P015B
The service bulletin suggests reprogramming the Engine Control Module (ECM) to fix the problem.

- High Fuel Consumption
- Excessive Smoke from Exhaust
P015B NISSAN SENTRA MeaningThe air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. The sensor element of the A/F sensor 1 is composed an electrode layer, which transports ions. It has a heater in the element. The sensor is capable of precise measurement λ = 1, but also in the lean and rich range. Together with its control electronics, the sensor outputs a clear, continuous signal throughout a wide λ range. The exhaust gas components diffuse through the diffusion layer at the sensor cell. An electrode layer is applied voltage, and this current relative oxygen density in lean. Also this current relative hydrocarbon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this electrode layer of current. In addition, a heater is integrated in the sensor to ensure the required operating temperature of approximately 760°C (1,400°F).
