What Does P2182 Code Mean?

    OBD-II Code P2182 is defined as a Engine Coolant Temperature Sensor 2 Circuit

    The Engine Coolant Temperature Sensor measures the temperature of the coolant going through the engine. The engine control module (PCM) uses this information to determine how much fuel to use to keep the engine running properly. It also uses this information to protect the engine from overheating. When the PCM detects a problem with this sensor or the circuit for the sensor, it will set code P2182.
