Code P0125 2017 Toyota RAV4 Description

The P0125 diagnostic trouble code (DTC) in a 2017 Toyota RAV4 indicates that there is insufficient coolant temperature for closed-loop fuel control. In simpler terms, this means that the engine is not reaching the optimal operating temperature required for efficient fuel combustion. The engine control module (ECM) monitors the coolant temperature to adjust the air-fuel mixture for optimal performance. When the coolant temperature is too low, the ECM may not be able to enter closed-loop fuel control mode, leading to decreased fuel efficiency and increased emissions.
