P2A00 2006 Nissan Altima Sedan Code - Air Fuel Ratio Sensor Circuit Range/Performance Bank 1 Sensor 1
Quick Answer
The Air Fuel Ratio (A/F) sensor is a planar dual-cell limit current sensor. Common causes include Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1, Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 harness is open or shorted, Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2A00 2006 Nissan Altima Sedan 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 P2A00 2006 Nissan Altima Sedan?
- Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1
- Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 harness is open or shorted
- Air Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection
- Fuel pressure
- Fuel injector
- Intake air leaks
How to Fix the DTC P2A00 2006 Nissan Altima Sedan?
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.

I have a 2006 Nissan Altima 2.5L and the service engine soon is on and i connect a 0BD2 diagnostic tool and it came out the P2A00 code, and it said Air Fuel Ratio Sensor 1 so i bought a new repacemet sensor and instaled but the service engine soon is still on i erase the code but 10 minutes later of driving my car the service engine soon came back on, what can i do to fix that problem?
-
Check for exhaust leaks near the sensor. If no leaks are found, perform the Clear Mixture Ratio Self-Learning Control Data procedure.
