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.

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.
