P014D Nissan Code - Air Fuel Ratio Sensor Slow Response - Lean To Rich Bank 1 sensor 1

Quick Answer

The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. Common causes include Faulty Air Fuel Ratio (A/F) Bank 1 Sensor 1, Air Fuel Ratio (A/F) Bank 1 Sensor 1 harness is open or shorted, Air Fuel Ratio (A/F) Bank 1 Sensor 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 P014D Nissan Description

The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. The sensor element of the A/F sensor 1 is composed an electrode layer, which transports ions. It has a heater in the element. 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. The exhaust gas components diffuse through the diffusion layer at the sensor cell. An electrode layer is applied voltage, and this current relative oxygen density in lean. Also this current relative hydrocarbon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this electrode layer of current. In addition, a heater is integrated in the sensor to ensure the required operating temperature of approximately 760°C (1,400°F).
