P015B Nissan Code - Air Fuel Ratio Delayed Response - Lean To Rich Bank 1 Sensor 1
Quick Answer
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. Common causes include 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. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P015B Nissan Description
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).
What are the Possible Causes of the DTC P015B Nissan?
- 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 to Fix the DTC P015B Nissan?
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.
Code Tech Notes
There is a Factory Service Bulletin for the following 2011-2012 Nissan Sentra:

Frequently Asked Questions about P015B Nissan Code
What does the OBDII code P015B mean on a Nissan?
P015B indicates a delayed response from the air-fuel ratio sensor (Bank 1 Sensor 1) when transitioning from a lean to a rich mixture, suggesting a potential issue with the sensor or related components.
What are the common symptoms of the P015B code on a Nissan?
Common symptoms include the check engine light turning on, reduced fuel efficiency, rough idling, hesitation during acceleration, and possibly poor engine performance.
What causes the P015B code to appear on a Nissan?
Possible causes include a faulty air-fuel ratio sensor, exhaust leaks, dirty or failing fuel injectors, vacuum leaks, or issues with the engine control module (ECM).
Can a dirty air filter trigger the P015B code?
Yes, a clogged or dirty air filter can disrupt the air-fuel mixture, potentially contributing to the delayed sensor response that triggers the P015B code.
How is the P015B code diagnosed?
A mechanic uses an OBDII scanner to confirm the code, checks the live data stream for sensor response, inspects for exhaust or vacuum leaks, and tests the air-fuel ratio sensor’s performance.
Can I keep driving with a P015B code on my Nissan?
While the vehicle may still run, ignoring the P015B code can lead to decreased fuel efficiency, potential damage to the catalytic converter, and worsening engine performance over time.
How can the P015B code be fixed on a Nissan?
Repairs may include replacing the air-fuel ratio sensor, fixing any exhaust or vacuum leaks, cleaning or replacing fuel injectors, or reprogramming/updating the ECM if needed.
How much does it cost to fix the P015B code on a Nissan?
Repair costs vary but typically range from $150 to $400 for parts and labor, depending on whether the air-fuel ratio sensor or other components need replacement.
Can bad fuel quality cause the P015B code?
Yes, poor-quality or contaminated fuel can affect the air-fuel ratio and sensor performance, potentially triggering the P015B code.
Is it necessary to replace the air-fuel ratio sensor to clear the P015B code?
Not always—other issues like exhaust leaks or vacuum leaks could be the root cause. Proper diagnosis is essential before replacing the sensor.
