Code P1286 2005 Nissan Maxima 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 λ 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 P1286 2005 Nissan Maxima?
- Faulty Air Fuel Ratio (A/F) Sensor 1 Bank 2
- Air Fuel Ratio (A/F) Sensor 1 Bank 2 harness is open or shorted
- Air Fuel Ratio (A/F) Sensor 1 Bank 2 circuit poor electrical connection
