Code C2184 Description
The C2184 diagnostic trouble code (DTC) indicates that the transmitter ID 4 signal is not being received by the vehicle's receiver module. In modern vehicles, tire pressure monitoring systems (TPMS) utilize transmitters within each tire to send data to the receiver module, which then alerts the driver if tire pressure is low. Transmitter ID 4 refers to the specific tire location in which the transmitter is not communicating with the receiver module.
Common Causes of C2184
- Faulty transmitter in the tire
- Low transmitter battery or battery failure
- Interference from electronic devices or other external factors
- Malfunctioning receiver module in the vehicle
- Wiring or communication issues between the transmitter and receiver
Symptoms of C2184
- TPMS warning light illuminates on the dashboard
- Inaccurate tire pressure readings displayed on the instrument cluster
- Loss of TPMS functionality, such as the inability to monitor tire pressure
- Increased tire wear or uneven tire pressure in specific locations
How to Fix C2184
- Begin by checking the battery life of the transmitter in tire ID 4 and replacing it if necessary.
- Inspect the wiring and connections between the transmitter and receiver module for any damage or loose connections.
- Use a TPMS tool to reset the system and re-establish communication between the transmitter and receiver.
- If the issue persists, replace the faulty transmitter in tire ID 4 or the receiver module, depending on the diagnosis.
- Test drive the vehicle to ensure the TPMS system is functioning correctly and that the transmitter ID 4 signal is being received.
Cost to Fix C2184
The typical repair costs for addressing the C2184 code can vary depending on the specific cause of the issue. In general, replacing a transmitter battery or resetting the system may cost between $50 to $150. However, if a faulty transmitter or receiver module needs to be replaced, the cost can range from $100 to $300 or more, including parts and labor. It's essential to consider the specific diagnosis time and labor rates at auto repair shops, which can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to consult with a professional technician for an accurate cost estimate tailored to your vehicle's needs.

Frequently Asked Questions about C2184 Code
1. What does OBDII code C2184 mean?
Code C2184 indicates that the vehicle's system did not receive the signal from the fourth tire pressure monitoring system (TPMS) transmitter, typically associated with one of the tires.
2. What are common symptoms of code C2184?
Common symptoms include the TPMS warning light illuminating on the dashboard and potentially inaccurate or missing tire pressure readings from one tire.
3. What causes code C2184 to appear?
The code is usually caused by a malfunctioning TPMS sensor, a dead sensor battery, signal interference, or an issue with the TPMS receiver module.
4. Can a faulty TPMS sensor trigger code C2184?
Yes, a faulty or damaged TPMS sensor is one of the most common causes of this code.
5. How do I diagnose code C2184?
To diagnose this code, use a TPMS scan tool to check for signal transmission from all sensors, inspect for physical damage to the sensors, and verify whether the TPMS receiver is functioning correctly.
6. Can code C2184 be caused by low tire pressure?
Low tire pressure itself doesn't cause this code, but it could indicate a sensor issue if the pressure is fine and the TPMS system is still malfunctioning.
7. How do you fix code C2184?
Fixes include replacing the faulty TPMS sensor, resetting the TPMS system, or addressing any signal interference or receiver malfunctions.
8. Do I need to replace all TPMS sensors if one fails?
Not necessarily. You can replace only the faulty sensor, but it might be a good idea to replace all sensors if they are nearing the end of their battery life.
9. Can a weak TPMS sensor battery cause code C2184?
Yes, a weak or dead TPMS sensor battery can prevent the transmitter from sending its signal, triggering this code.
10. Is it safe to drive with code C2184 active?
While the vehicle may still be drivable, it’s important to address the issue promptly as you may not receive accurate tire pressure warnings, which could compromise safety.
