P0152 2009 Nissan Sentra Code - Air Fuel Ratio Circuit High Bank 2 Sensor 1
Quick Answer
The Air Fuel Ratio (A/F) sensor is a planar dual-cell limit current sensor. Common causes include Faulty Front Heated Oxygen Sensor Bank 2, Intake air leaks may be faulty, Exhaust gas leaks. 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 P0152 2009 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 P0152 2009 Nissan Sentra?
- Faulty Front Heated Oxygen Sensor Bank 2
- Intake air leaks may be faulty
- Exhaust gas leaks
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
