The fault code P2181 indicates a problem with the engine’s cooling system. The diagnosis involves checking the coolant level, inspecting the thermostat, and testing the coolant temperature sensor. The estimated repair time for this fault code is 1.0 hour.

The fixing cost will depend on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may affect the cost include the severity of the problem and the type of vehicle.

The P2181 code is related to the cooling system performance of the vehicle.

The Engine Control Module (ECM) is responsible for monitoring the Engine Coolant Temperature Sensor signal to determine the engine temperature. If the signal from the sensor is not within the factory specifications, the ECM will set the OBDII code P2181. This fault code indicates that there is an issue with the cooling system of the vehicle, which could lead to engine overheating and other related problems.

It is important to address this issue promptly to avoid further damage to the engine and ensure the safe operation of the vehicle.
