DTC P2183: Engine Coolant Temperature (ECT) Sensor 2 Performance Problem: General Description

Two engine coolant temperature sensors and one intake air temperature sensor are used by the powertrain control module (PCM).

When the engine stops and enough time has passed, the temperature of the engine will equal the ambient temperature. When an inappropriate temperature is detected after comparing the temperature readings of each sensor, a malfunction in the corresponding sensor is detected and a DTC is stored.
