What is the error code for air fuel ratio sensor?
Error Code P1273 is described as Air Fuel Ratio Sensor 1 Bank 1 Lean Shift Monitoring. This refers to a lean condition due to too much oxygen, usually caused by a vacuum leak, fuel pressure, dirty MAF (Mass Airflow sensor), or defective or dirty injectors.
Can a diesel engine air ratio sensor work?
NOTE: Due to the many variables that operate in diesel engines, the stoichiometric air/fuel mixture for these applications vary, but suffice to say that Air/Fuel Ratio sensors work equally well on diesel engines.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
What’s the difference between AFR and O2 sensors?
What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor. It can detect a wider range of air/fuel ratios than the basic O2 sensor.
What are the specifications for an air fuel ratio sensor?
The sensor must have a resistance specifications of: To check further, technicians will check for short or open in the harness of the Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1. Next, they will check for poor electrical connections in Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1. Exhaust leaks near the sensors must also be checked.
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
Can a bad air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light .
What are error codes for mass air flow sensor?
For doing so you only need to connect your code reader and turn the ignition key on (engine off), a state usually known as KOEO. Common error codes include P0299 (if turbocharger is fitted), P0300, P0101, P0102 and P0171.
How much does it cost to diagnose Nissan p1271 code?
The cost of diagnosing the P1271 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
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.
Is the error code P1273 a generic code?
Unlike most error codes, this code is NOT a generic trouble code, meaning it does NOT apply to all vehicles with OBD-II system or vehicles made since 1996 up to present. Rather, it is a vehicle specific code, which applies to certain makes of vehicles, most commonly among Nissan cars.
What is the air fuel ratio sensor P1273?
P1273 Nissan Description. The 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.
What does the code P1273 Nissan mean?
P1273 NISSAN Possible Causes Faulty Air fuel ratio (A/F) Sensor 1 Bank 1 Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection Fuel pressure Faulty Fuel injector Faulty Air Flow Meter What does this mean? How do I fix code P1273 NISSAN
The cost of diagnosing the P1271 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
What kind of sensor is the air fuel ratio sensor?
