P0133 2011 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 2011 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 2011 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 2011 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.
