What causes bad air-fuel ratio?
Problems with air fuel ratio sensors are common. Often a sensor gets contaminated or simply fails. In some cars, the heating element inside the sensor fails causing the malfunction. For example, in many Toyota and Honda cars the code P0135 may be caused by a failed heating element inside the sensor.
What does the P1273 Nissan air fuel ratio sensor mean?
P1273 NISSAN Meaning. 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 are the possible causes of a Nissan p1283?
P1283 NISSAN 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.
How long does it take to diagnose Nissan P1273 code?
If one or more sensors are replaced the Engine Control Module (ECM) Mixture Ratio Self-Learning clearing procedure must be performed. The cost to diagnose the P1273 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 causes faulty air fuel ratio in Nissan?
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
