Code P2184 Dodge Description
The P2184 diagnostic trouble code for Dodge vehicles indicates a problem with the Engine Coolant Temperature Sensor 2 Circuit being lower than normal. The Engine Coolant Temperature Sensor (ECT) is a crucial component that monitors the temperature of the engine coolant. It sends this information to the engine control module (ECM), which uses it to adjust fuel injection, ignition timing, and other engine functions.
Common Causes of P2184 Dodge
- Faulty Engine Coolant Temperature Sensor: The most common cause of the P2184 code is a malfunctioning Engine Coolant Temperature Sensor.
- Wiring Issues: Damaged or corroded wiring connected to the sensor can cause inaccurate readings and trigger the code.
- Coolant Level: Low coolant levels can affect the sensor's ability to accurately measure the engine's temperature.
- Cooling System Problems: Issues with the cooling system, such as a malfunctioning thermostat or a clogged radiator, can impact the sensor's performance.
Symptoms of P2184 Dodge
- Check Engine Light: The most common symptom associated with the P2184 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Efficiency: A faulty engine coolant temperature sensor can cause the engine to run rich, resulting in decreased fuel efficiency.
- Rough Idling: The engine may idle roughly or inconsistently when the coolant temperature sensor is malfunctioning.
- Engine Overheating: Inaccurate temperature readings from the sensor can lead to engine overheating, which can cause serious damage if not addressed.
- Engine Misfires: A malfunctioning ECT sensor can cause the engine to misfire, leading to rough running or stalling.
How to Fix P2184 Dodge
- Diagnose the Issue: Use a scan tool to read the code and confirm that it is indeed related to the Engine Coolant Temperature Sensor 2 Circuit Low.
- Inspect Wiring: Check the wiring harness connected to the sensor for any damage or corrosion. Repair or replace as necessary.
- Replace Coolant Temperature Sensor: If the sensor is faulty, it will need to be replaced with a new one.
- Check Coolant Levels: Ensure that the coolant levels are adequate and that there are no leaks in the cooling system.
- Clear Codes: After the repair is completed, clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2184 Dodge
The cost of repairing the P2184 code for a Dodge vehicle can vary depending on the specific model and year. On average, replacing the Engine Coolant Temperature Sensor can range from $50 to $150 for the part. Labor costs can add an additional $80 to $150 per hour, with the total repair bill likely falling between $150 and $300. It's important to note that these are rough estimates and actual costs may vary based on the location of the repair shop, the vehicle's make and model, and any additional parts or services needed.

Frequently Asked Questions about P2184 Dodge Code
1. What does the OBDII code P2184 mean on a Dodge vehicle?
P2184 indicates that the Engine Control Module (ECM) has detected a low voltage signal from the Engine Coolant Temperature (ECT) Sensor 2, suggesting a circuit issue.
2. What are the common symptoms of code P2184 in a Dodge?
Symptoms may include poor fuel efficiency, engine overheating, difficulty starting the engine, erratic temperature gauge readings, and the check engine light turning on.
3. What causes the P2184 code to appear?
Common causes include a faulty ECT sensor, damaged wiring or connectors in the ECT sensor circuit, low coolant levels, or a malfunctioning ECM.
4. Can I still drive my Dodge with the P2184 code active?
While the vehicle may still operate, driving with this code can risk engine overheating and potential damage. It’s best to address the issue promptly.
5. How do I diagnose the P2184 code on a Dodge?
Start by inspecting the ECT sensor and its wiring for damage or corrosion. Check for proper voltage and resistance readings using a multimeter. Verify coolant levels and ensure there are no leaks.
6. How do you fix code P2184 on a Dodge vehicle?
Repairs may include replacing the faulty ECT sensor, repairing or replacing damaged wiring/connectors, refilling coolant, or resetting the ECM after the issue is resolved.
7. Is it expensive to fix the P2184 code on a Dodge?
Repair costs depend on the root cause. Replacing the ECT sensor typically costs $50–$150, while fixing wiring or ECM issues can be more expensive.
8. Can low coolant levels trigger the P2184 code?
Yes, low coolant levels can cause inaccurate readings from the ECT sensor, leading to this code.
9. How do I prevent the P2184 code from recurring on my Dodge?
Regularly check coolant levels, inspect the cooling system for leaks, and maintain the ECT sensor and wiring to prevent future issues.
10. Will clearing the P2184 code solve the problem?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be fixed to prevent the code from returning.
