C2224 Code - Transmitter 4 Pressure Data Abnormal
Quick Answer
The Tire Pressure Monitor (TPM) system checks the tire pressures of all 4 road wheels when the vehicle is driven at speeds above 25 mph (40 km/h), and warns in the event of a loss of pressure by means of a low tire pressure warning light. Common causes include Tire pressure not to factory specifications, Faulty Tire Pressure Transmitter, Faulty Tire Pressure Monitor System (TPMS) Control Module. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C2224 Description
What are the Possible Causes of the DTC C2224?
- Tire pressure not to factory specifications
- Faulty Tire Pressure Transmitter
- Faulty Tire Pressure Monitor System (TPMS) Control Module
How to Fix the DTC C2224?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
If the warning light is still on after adjusting tire pressure, check for a damaged tire and repair as necessary. If warning light blinks 25 times and then illuminates, and there is not a tire without a tire pressure sensor installed, there is a malfunction in the TPM system. See appropriate manufacturer service information.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the C2224 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about C2224 Code
1. What are common symptoms of OBDII code C2224?
Possible symptoms include erratic tire pressure readings, tire pressure warning light illumination, and issues with the tire pressure monitoring system (TPMS).
2. What can cause OBDII code C2224 to trigger?
This code is typically triggered by issues such as a faulty tire pressure sensor, sensor wiring problems, low tire pressure, or sensor calibration errors.
3. How can I diagnose the cause of OBDII code C2224?
Diagnosing this code often involves using a TPMS tool to read sensor data, checking tire pressure levels, inspecting sensor wiring for damage, and verifying sensor calibration.
4. Can low tire pressure cause OBDII code C2224 to be set?
Yes, low tire pressure can trigger this code as the system may interpret the pressure data as abnormal due to the discrepancy between the readings from the affected sensor and the other sensors.
5. What are some repair tips for addressing OBDII code C2224?
Repair tips may include inflating tires to the correct pressure, resetting the TPMS system, replacing faulty sensors, repairing damaged wiring, and performing sensor calibration procedures.
6. Is it safe to continue driving with OBDII code C2224 present?
It is generally safe to drive with this code, but it is important to address the underlying issue promptly to ensure the proper functioning of the TPMS and accurate tire pressure monitoring.
7. Can a DIY enthusiast fix OBDII code C2224 at home?
Depending on their skill level and access to tools, DIY enthusiasts may be able to address this code by performing tasks such as checking tire pressure, inspecting sensor wiring, and replacing sensors.
8. How much does it typically cost to repair OBDII code C2224 at a mechanic or dealership?
The cost of repairing this code can vary depending on the underlying issue, but it may involve expenses such as sensor replacement, wiring repairs, labor costs, and potential TPMS system recalibration.
9. Will resetting the OBDII system clear code C2224, or is a more thorough repair needed?
Resetting the OBDII system may temporarily clear the code, but if the underlying issue persists, the code is likely to reappear. A more thorough repair is recommended to address the root cause.
10. Can extreme temperatures or driving conditions affect the accuracy of tire pressure sensors and trigger code C2224?
Yes, extreme temperatures and driving conditions can impact the accuracy of tire pressure sensors, potentially leading to abnormal pressure data readings and the triggering of code C2224. Regular maintenance and monitoring can help mitigate these effects.
