What is the p1283 Nissan air fuel ratio sensor?
P1283 Nissan Description The 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.
What can cause an O2 sensor to set a different code?
There are also some other possibilities such as an internally leaking EGR system. This will typically set a separate code. A leak in the exhaust system before the (O2) sensor will also cause incorrect readings. The only other possibilities are wiring issues, and computer concerns.
What does Service Bulletin OBDII code p1283 mean?

How does the zirconium sensor measure fuel ratio?
At the extreme ends of its range, the zirconium sensor can measure only an approximate 14.2:1 (rich) to about 15.2:1 (lean) AFR. The less oxygen present in the exhaust stream (rich), the greater the signal voltage, and the more oxygen present in the exhaust stream (lean), the lower the signal voltage.

What causes a faulty air fuel ratio sensor?
Possible causes. 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. Low fuel pressure. Faulty Fuel injector. Intake air leaks. Faulty Air Flow Meter.
How is the oxygen sensor used in fuel control?
Fig. 4: Notice that the rear or downstream oxygen sensor is producing about 0.800 mV, which is slightly high for a post-catalyst sensor. Modern fuel control systems use the downstream sensor as part of the fuel control system and to serve as a default sensor if the upstream sensor fails.
