Code P2182 Honda Description

Engine Coolant Temperature (ECT) Sensor 2 is a thermistor attached to the radiator. The Powertrain Control Module (PCM) applies a voltage (about 5 V) to the signal circuit through a pull-up resistor. As the engine coolant temperature cools, the ECT sensor 2 resistance increases and the PCM detects a high signal voltage. As the engine coolant warms, the ECT sensor 2 resistance decreases and the PCM detects a low signal voltage. If the ECT sensor 2 output voltage is in a specified range for a specified time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
