P0133 2006 Nissan Sentra 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 2006 Nissan Sentra 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 2006 Nissan Sentra?
- 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 2006 Nissan Sentra?
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.

Frequently Asked Questions about P0133 2006 Nissan Sentra Code
1. What does OBDII code P0133 for a 2006 Nissan Sentra mean?
- This code indicates a slow response in the air fuel ratio circuit for Bank 1 Sensor 1, which is the upstream oxygen sensor located before the catalytic converter.
2. What are the common symptoms of P0133 in a 2006 Nissan Sentra?
- Common symptoms include poor fuel economy, rough idling, hesitation during acceleration, and potential stalling of the engine.
3. What are the possible causes of a P0133 code in a 2006 Nissan Sentra?
- The most common causes include a faulty oxygen sensor, issues with the wiring or connectors related to the sensor, exhaust leaks near the sensor, or a vacuum leak in the intake system.
4. How can I diagnose the P0133 code in my 2006 Nissan Sentra?
- Diagnosing the code may involve visually inspecting the oxygen sensor and its connections, checking for exhaust leaks, testing the sensor's voltage output, and using a scan tool to monitor sensor data.
5. Can I drive my 2006 Nissan Sentra with a P0133 code?
- It is not recommended to drive the vehicle with a P0133 code for an extended period as it can lead to poor engine performance and potentially cause damage to the catalytic converter.
6. How do I repair a P0133 code in my 2006 Nissan Sentra?
- Repair options may include replacing the Bank 1 Sensor 1 oxygen sensor, repairing or replacing damaged wiring or connectors, fixing any exhaust leaks, or addressing any vacuum leaks in the intake system.
7. Is it possible to reset the P0133 code in a 2006 Nissan Sentra?
- Resetting the code using an OBDII scanner may temporarily clear the code, but if the underlying issue causing the code is not fixed, the code is likely to reappear.
8. Are there any DIY repair tips for fixing a P0133 code in a 2006 Nissan Sentra?
- DIY tips may include checking for visible damage to the oxygen sensor and its connections, inspecting for exhaust leaks, and ensuring proper installation of the sensor.
9. How much does it cost to repair a P0133 code in a 2006 Nissan Sentra?
- The cost of repair can vary depending on the exact cause of the code, but it may range from $100 to $300 for parts and labor if the oxygen sensor needs replacement.
10. Can a P0133 code in a 2006 Nissan Sentra cause emissions issues?
- Yes, a P0133 code can affect emissions by causing the vehicle to run less efficiently and potentially increasing harmful emissions. It is important to address the code promptly to maintain proper emissions levels.

My '06 Sentra had thrown a P2A00 code for A/F Sensor 1 Bank 1 so I purchased a new sensor, had it installed and cleared the CEL and all codes. I drove about 100 miles and now I'm getting a P0133 code which is just another way of indicating that the same sensor is bad...but it's brand new and was just replaced. Any suggestions?

Do you have any exhaust leaks? If no leaks found (even an small leak will set the code), then the next step is to Clear Mixture Ratio Self-Learning Control Data.
