P0133 2011 Nissan Pathfinder Code - Air Fuel Ratio Circuit Slow Response Bank 1 Sensor 1
Quick Answer
The Air Fuel Ratio (A/F) sensor is a planar dual-cell limit current sensor. Common causes include Faulty Air fuel ratio (A/F) sensor 1 bank 1, Air fuel ratio (A/F) sensor 1 bank 1 harness is open or shorted, Air fuel ratio (A/F) sensor 1 bank 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 P0133 2011 Nissan Pathfinder Description
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 range (0.7 < λ < air).
The exhaust gas components diffuse through the diffusion gap at the electrode of the oxygen pump and Nernst concentration cell, where they are brought to thermodynamic balance. An electronic circuit controls the pump current through the oxygen pump cell so that the composition of the exhaust gas in the diffusion gap remains constant at λ = 1. Therefore, the A/F sensor is able to indicate air/fuel ratio by this pumping of current. In addition, a heater is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).
What are the Possible Causes of the DTC P0133 2011 Nissan Pathfinder?
- Faulty Air fuel ratio (A/F) sensor 1 bank 1
- Air fuel ratio (A/F) sensor 1 bank 1 harness is open or shorted
- Air fuel ratio (A/F) sensor 1 bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
How to Fix the DTC P0133 2011 Nissan Pathfinder?
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.

1. What does OBDII code P0133 on a 2011 Nissan Pathfinder mean?
This code, Air Fuel Ratio Circuit Slow Response Bank 1 Sensor 1, indicates a slow response from the oxygen sensor in bank 1 sensor 1, which is located before the catalytic converter.
2. What are the common symptoms of OBDII code P0133 on a 2011 Nissan Pathfinder?
Common symptoms include reduced fuel efficiency, rough idling, engine misfires, and an illuminated check engine light on the dashboard.
3. What are the possible causes of OBDII code P0133 on a 2011 Nissan Pathfinder?
Potential causes of this code include a faulty oxygen sensor, issues with the wiring or connections to the sensor, vacuum leaks, exhaust leaks, or a problem with the engine's air-fuel mixture.
4. How can I diagnose the cause of OBDII code P0133 on a 2011 Nissan Pathfinder?
Diagnosing this code typically involves using an OBDII scanner to read the code, inspecting the oxygen sensor and related wiring for damage, checking for vacuum and exhaust leaks, and testing the sensor's response with a multimeter.
5. Can I continue to drive my 2011 Nissan Pathfinder with OBDII code P0133?
While your vehicle may still be driveable with this code, it is recommended to address the issue promptly to prevent potential damage to the catalytic converter and ensure optimal engine performance.
6. How can I repair OBDII code P0133 on a 2011 Nissan Pathfinder?
Repair options may include replacing the oxygen sensor in bank 1 sensor 1, repairing any damaged wiring or connections, fixing vacuum or exhaust leaks, and addressing issues with the air-fuel mixture as needed.
7. Is it possible to reset OBDII code P0133 on a 2011 Nissan Pathfinder without fixing the underlying issue?
Resetting the code without addressing the underlying problem will only temporarily turn off the check engine light. The issue causing the code will persist and may lead to more serious problems if left unresolved.
8. How much does it cost to fix OBDII code P0133 on a 2011 Nissan Pathfinder?
The cost of fixing this code can vary depending on the specific cause of the issue. Costs may include the price of a new oxygen sensor, labor for installation, and any additional repairs needed.
9. Can a DIY enthusiast repair OBDII code P0133 on a 2011 Nissan Pathfinder?
While some DIY enthusiasts may be able to replace the oxygen sensor themselves, diagnosing and repairing other potential causes of the code may require professional knowledge and tools.
10. How often should I check the oxygen sensors on my 2011 Nissan Pathfinder to prevent OBDII code P0133?
Regular maintenance checks, such as during scheduled service intervals, can help detect issues with the oxygen sensors early and prevent the occurrence of codes like P0133.
