P0150 NISSAN - Air Fuel Ratio Circuit Bank 2 Sensor 1
P0150 NISSAN Possible Causes
- Faulty Air fuel ratio (A/F) sensor bank 2 sensor 1
- Air fuel ratio (A/F) sensor bank 2 sensor 1 harness is open or shorted
- Air fuel ratio (A/F) sensor bank 2 sensor 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
First diagnose P0150 NISSAN code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
P0150 NISSAN Tech NotesReplacing the Air fuel ratio (A/F) sensor bank 2 sensor 1 usually takes care of the problem.

Cost of diagnosing the P0150 NISSAN code
Labor: 1.0The cost of diagnosing the P0150 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0150 NISSAN code detected?The Air Fuel Ratio (A/F) signal computed by Engine Control Module (ECM) from the A/F sensor 1 signal is constantly in the range other than approx. 1.5V.
P0150 NISSAN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
P0150 Nissan DescriptionThe Air Fuel Ratio (A/F) sensor is a planar dual-cell limit current sensor. The sensor element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, 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 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).
