What is the B0061 fault code?
The B0061 fault code, applicable to all car manufacturers, means “Passenger Seatbelt Tension Sensor (Subfault)“.
Background Information: The function of the seatbelt tension sensor is to electronically transmit the tension of the seatbelt during a collision to the airbag control module, serving as an important parameter for the airbag’s deployment decision. This sensor effectively prevents the passenger airbag from deploying when there is no passenger or when the passenger’s weight is below a certain range.
Symptoms of Error Code B0061
Signs of error B0061 may include:
- The airbag light on the dashboard is illuminated
- The SRS (airbag) system is disabled
- Failure to pass inspection due to an active error
- In some cases, there will be an audible warning signal
Main Causes of Error Code B0061
- Faulty seatbelt tension sensor itself
- Damaged or broken wiring connecting the sensor to the control unit
- Corroded or contaminated connector
- Faulty SRS system control module

B0061 Frequently Asked Questions
Can you drive with error code B0061?
It is not recommended, as the error may affect the airbag system operation and reduce the level of passive occupant protection in the event of an accident.
Will replacing the seatbelt remove error B0061?
If the error is caused by a faulty tension sensor, replacing the seatbelt with the sensor will eliminate the fault code. However, the error must be reset using a diagnostic scanner.
Is it possible to reset code B0061 without repair?
It can be reset via an OBD-II scanner or by disconnecting the battery, but the error will reappear if the fault is not resolved.
Do I need a diagnostic service if error B0061 occurs?
Yes, especially if you are unsure of the cause of the error. Only a complete diagnosis can ensure accurate identification of the faulty component.
Could the B0061 error be caused by connector corrosion?
Yes, oxidation or contamination of the connector can interfere with the sensor signal, leading to error B0061.
