P219E 2017 Toyota RAV4 Code - Cylinder 3 Air-Fuel Ratio Imbalance
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 P219E 2017 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.
The ECM uses the air-fuel ratio sensor and crankshaft position sensor to monitor the difference in air-fuel ratios between the cylinders caused by differences in injection volumes between the cylinders, leakage in the intake or exhaust system, etc.
When the air-fuel ratios of the cylinders are lean or rich with respect to each other, the ECM determines that there is a malfunction, illuminates the MIL, and stores a Diagnostic Trouble Code (DTC).
The system monitors the engine speed variation and when the variation becomes large, the ECM determines that there is a difference in air-fuel ratios between the cylinders, which it determines to be a malfunction.
What are the Possible Causes of the DTC P219E 2017 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)
