Code P050A 2014 Toyota RAV4 Description
The DTC is designed to monitor the idle air control at a cold start. When the engine is started at an engine coolant temperature of below 50°C (122°F), the Engine Control Module (ECM) measures the accumulated mass air flow during engine idling. If the accumulated mass air flow does not reach the specified level within 10 seconds, the ECM interprets this as a malfunction. The MIL is illuminated, and a DTC is stored when the malfunction is detected in consecutive driving cycles (2 trip detection logic).
The electronic throttle control system controls the idle speed. The electronic throttle control system operates the throttle actuator to open and close the throttle valve and adjusts the intake air amount to achieve the target idle speed.
What are the Possible Causes of the DTC P050A 2014 Toyota RAV4?
