Code C2124 Scion Description
The C2124 diagnostic trouble code (DTC) for Scion vehicles indicates that there is no signal being received from Transmitter ID 4 in the main mode. In simpler terms, this means that the vehicle's onboard computer is not receiving data from the transmitter associated with ID 4, which is likely a tire pressure monitoring system (TPMS) sensor. The TPMS system is designed to monitor the air pressure in the tires and alert the driver if there is a significant deviation from the recommended pressure.
Common Causes of C2124 Scion
- Faulty TPMS sensor for Transmitter ID 4
- Wiring issues or corrosion in the TPMS system
- Faulty receiver in the vehicle's computer system
- Low battery in the TPMS sensor
- Interference from other electronic devices affecting the TPMS signal
Symptoms of C2124 Scion
- TPMS warning light illuminated on the dashboard
- Inaccurate or inconsistent tire pressure readings displayed on the instrument cluster
- Loss of communication with other TPMS sensors
- Decreased fuel efficiency
- Uneven tire wear
How to Fix C2124 Scion
- Begin by checking the tire pressure in all four tires manually to ensure they are properly inflated.
- Inspect the TPMS sensor associated with Transmitter ID 4 for any visible damage or corrosion.
- Test the sensor's battery voltage and replace it if necessary.
- Check the wiring and connections in the TPMS system for any breaks or loose connections.
- Use a diagnostic scan tool to reset the TPMS system and relearn the sensor IDs.
Cost to Fix C2124 Scion
The typical repair costs for addressing a C2124 code on a Scion vehicle can vary depending on the specific cause of the issue. In general, replacing a faulty TPMS sensor can cost between $50 and $200 per sensor, including parts and labor. Wiring repairs or system resets may incur additional charges. It is advisable to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that diagnostic time and labor rates can vary, so it's recommended to inquire about these costs upfront.

Frequently Asked Questions about C2124 Scion Code
What does the OBDII code C2124 mean on a Scion?
C2124 indicates that the vehicle's Tire Pressure Monitoring System (TPMS) is not receiving a signal from Transmitter ID 4, typically associated with one of the tire pressure sensors.
What are the symptoms of the C2124 code on a Scion?
Common symptoms include the TPMS warning light illuminating on the dashboard and, in some cases, inaccurate tire pressure readings or no readings for the affected tire.
What causes the C2124 code to appear on a Scion?
The most common causes are a dead or faulty TPMS sensor, a damaged sensor, interference with the sensor's signal, or a sensor that has not been programmed or registered correctly.
How can I diagnose the C2124 code on a Scion?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the TPMS sensor on the affected tire, and checking for physical damage, dead batteries, or improper registration.
Can I drive my Scion with the C2124 code active?
Yes, you can still drive the vehicle, but the TPMS system will not function correctly, increasing the risk of driving with improperly inflated tires.
How can I fix the C2124 code on a Scion?
The issue can often be resolved by replacing the faulty TPMS sensor, ensuring it is properly programmed, and clearing the code with an OBDII scanner.
How much does it cost to repair the C2124 code on a Scion?
Replacing a TPMS sensor typically costs $50–$100 for parts and $50–$150 for labor, depending on the shop and location.
Can the C2124 code be caused by a dead TPMS sensor battery?
Yes, a dead TPMS sensor battery is a common cause of the C2124 code, as it prevents the sensor from transmitting data to the vehicle's computer.
How do I prevent the C2124 code from occurring?
Regularly inspect and maintain the TPMS sensors, replace them when their batteries are depleted (usually every 5–10 years), and ensure new sensors are properly programmed.
Do I need to reprogram the TPMS after replacing a sensor to clear the C2124 code?
Yes, after replacing a TPMS sensor, it must be programmed and registered to the vehicle’s TPMS system to ensure proper communication and to clear the code.
