Potential Causes of the P2181 Code
Several issues could trigger the P2181 code in your Kia Sorento:
- Faulty engine coolant temperature sensor: This sensor monitors the engine’s coolant temperature. If it fails, it can send incorrect signals to the engine control module.
- Thermostat failure: A stuck or malfunctioning thermostat can prevent coolant from circulating properly.
- Coolant leaks: Any leak within the cooling system can lead to insufficient coolant levels, affecting engine temperature regulation.
- Radiator issues: Blockages or damage in the radiator can impede coolant flow, causing overheating.
- Water pump failure: The water pump is crucial for circulating coolant. If it's defective, the cooling system won't function correctly.
