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.

MONITOR DESCRIPTION

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

A malfunction is detected if these three conditions are present after the engine and the ignition switch have been
off for at least 6 hours before restarting the engine.



When the temperature difference between the IAT and ECT1 is 61 °F (34 °C) or more.



When the temperature difference between the IAT and ECT2 is 28 °F (16 °C) or more.



When the temperature difference between the ECT2 and ECT1 is 60 °F (33 °C) or more.

Driving Pattern

1. Turn the ignition off, and wait at least 6 hours.

2. Start the engine, and let it idle for at least 10 seconds.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the
freeze frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.

DTC P2184 (192): ADVANCED DIAGNOSTICS

DTC P2184: ENGINE COOLANT TEMPERATURE (ECT) SENSOR 2 CIRCUIT LOW VOLTAGE

Fig. 226: Engine Coolant Temperature (ECT) Sensor 2 Circuit Diagram

Fig. 227: Engine Coolant Temperature Sensor Output Voltage - Graph

General Description

The engine coolant temperature (ECT) sensor 2 is a thermistor attached to the radiator. The ECM/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 ECM/PCM detects a high signal voltage. As the engine
coolant warms, the sensor resistance decreases, and the ECM/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
ECM/PCM detects a malfunction and a DTC is stored.
