P014D 2013 Toyota RAV4 Code - A/F Sensor Slow Response - Lean to Rich Bank 1 Sensor 1
Quick Answer
The Air Fuel Ratio (A/F) sensor generates a voltage that corresponds to the actual air-fuel ratio. Common causes include Faulty Air Fuel Ratio (A/F) Sensor, Air Fuel Ratio Sensor harness is open or shorted, Air Fuel Ratio Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P014D 2013 Toyota RAV4 Description
The air-fuel ratio sensor is a planar type and is integrated with the heater, which heats the solid electrolyte (zirconia element). This heater is controlled by the ECM. When the intake air volume is low (the exhaust gas temperature is low), a current flows into the heater to heat the sensor, in order to facilitate accurate oxygen concentration detection. In addition, the sensor and heater portions are narrow types. The heat generated by the heater is conducted to the solid electrolyte through the alumina, and therefore sensor activation is accelerated.
In order to obtain a high purification rate of the carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) components in the exhaust gas, a three-way catalytic converter is used. For the most efficient use of the three-way catalytic converter, the air-fuel ratio must be precisely controlled so that it is always close to the stoichiometric level.
After the engine has been warmed up, the ECM carries out air-fuel ratio feedback control and maintains the air-fuel ratio at the theoretical level. In addition, after all the preconditions have been met, active air-fuel ratio control is carried out for approximately 10 seconds and during active air-fuel ratio control, the ECM measures the response of the air-fuel ratio sensor by increasing or decreasing a specific injection quantity based on the theoretical air-fuel ratio learned during normal air-fuel control. The ECM determines whether there is an air-fuel ratio sensor malfunction at the mid-point of active air-fuel ratio control.
If the air-fuel ratio sensor's response-ability is reduced, the Diagnostic Trouble Code (DTC) P014D is output.
What are the Possible Causes of the DTC P014D 2013 Toyota RAV4?
- Faulty Air Fuel Ratio (A/F) Sensor
- Air Fuel Ratio Sensor harness is open or shorted
- Air Fuel Ratio Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
