P2184 2009 HONDA ACCORD MeaningEngine Coolant Temperature (ECT) sensor 2 is a thermistor attached to the radiator. The Powertrain Control Module (PCM) applies voltage (about 5 V) to the ECT2 signal circuit through a pull up resistor. As the engine coolant temperature cools, ECT sensor 2 resistance increases, and the PCM detects a high signal voltage. As the engine coolant warms, the sensor resistance decreases, and the PCM detects a low ECT2 signal voltage. If the ECT sensor 2 output voltage is less than a set value when the engine coolant temperature is high, the PCM detects a malfunction and a DTC is stored.
