Code C2141 Scion Description

The Tire Pressure Warning Valve and Transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the Tire Pressure Warning ECU and Receiver in the vehicle as radio waves. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the warning light in the combination meter assembly illuminates.
When the internal circuit of a Tire Pressure Warning Valve and Transmitter is malfunctioning, this Diagnostic Trouble Code (DTC) is output.

Frequently Asked Questions about C2141 Scion Code

1. What does the OBDII code C2141 mean on a Scion?

C2141 indicates a "Transmitter ID 1 Error" related to the vehicle's tire pressure monitoring system (TPMS), meaning the system is unable to recognize or communicate with one of the TPMS sensors.

2. What are the common symptoms of a C2141 code?

The most common symptom is the TPMS warning light illuminating on the dashboard. You may also notice inaccurate or missing tire pressure readings.

3. What causes the C2141 code to appear?

This code is usually caused by a faulty TPMS sensor, a sensor with a dead battery, incorrect sensor programming, or interference with the signal transmission.

4. How can I fix the C2141 code on my Scion?

Inspect and replace the affected TPMS sensor if itâ€™s damaged or has a dead battery. Reprogram or relearn the sensor ID into the TPMS system using a diagnostic scan tool.

5. Can I drive my Scion with a C2141 code?

Yes, but you should address the issue promptly since the TPMS system may not correctly alert you to low tire pressure, increasing the risk of a blowout or unsafe driving conditions.

6. How do I know which TPMS sensor is causing the C2141 code?

A diagnostic scan tool can identify the specific sensor with the transmitter ID error. Alternatively, a technician can use a TPMS reader to locate the problematic sensor.

7. Does replacing a tire cause the C2141 code to appear?

Yes, if the TPMS sensor is damaged during tire replacement or if the new tire lacks a properly programmed sensor, it can trigger the code.

8. Can a weak TPMS sensor battery cause the C2141 code?

Yes, a weak or dead TPMS sensor battery is a common cause of this code, as it prevents the sensor from transmitting its ID to the system.

9. Will resetting the TPMS system clear the C2141 code?

In some cases, resetting the TPMS system using a scan tool or the vehicleâ€™s built-in reset procedure can clear the code, but only if there are no underlying sensor issues.

10. How much does it cost to fix a C2141 code on a Scion?

Repair costs vary but typically range from $50 to $150 per TPMS sensor, plus labor if professional reprogramming or replacement is needed.
