- 05-21 Code: Engine Overheating
- The 05-21 code signals that the engine is running too hot, which could be due to issues with the cooling system, low coolant levels, a clogged radiator, or a malfunctioning temperature sensor. Operating at high temperatures for extended periods can damage the engine, so it's important to check the cooling system immediately.

- Inspect the Cooling System
- For the 05-21 error code, inspect the coolant levels and ensure the radiator is not clogged. If the coolant is low, add the appropriate coolant. If the radiator is dirty or clogged, clean it to ensure proper airflow. Also, check the temperature sensor and cooling pump to make sure they are functioning properly.
