P015A 2013 NISSAN ROGUE - Air Fuel Ratio Delayed Response - Rich To Lean Bank 1 Sensor 1

Repair Importance Level: 2/3
Repair Difficulty Level: 2/3  What does this mean?

P015a 2013 Nissan Rogue Possible Causes

  • 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

P015a 2013 Nissan Rogue Tech Notes

Replacing the Air Fuel Ratio Bank 1 Sensor 1 usually takes care of the problem.

When is the code detected?

The response time of a A/F sensor 1 signal delays more than the specified time computed by Engine Control Module (ECM).

P015a 2013 Nissan Rogue Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • High Fuel Consumption
  • Excessive Smoke from Exhaust

P015a 2013 Nissan Rogue Meaning

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).
