Code U047E Description
The diagnostic trouble code U047E indicates that the vehicle's onboard computer has detected invalid data being received from the Restraints System Sensor 'N'. The Restraints System Sensor is a critical component of the vehicle's safety system, responsible for monitoring the status of the airbags, seatbelt pretensioners, and other safety features. When the sensor detects a potential issue, it sends data to the vehicle's computer for analysis.
Common Causes of U047E
- Faulty Restraints System Sensor 'N'.
- Wiring or connection issues.
- Damage to the sensor connector.
- Malfunctioning onboard computer.
Symptoms of U047E
- Airbag warning light illuminated on the dashboard.
- Seatbelt warning light stays on.
- Inability to reset the airbag system codes.
- Airbags not deploying in a collision.
How to Fix U047E
- Use a diagnostic scanner to retrieve the specific fault code and identify the affected sensor.
- Inspect the wiring and connections to the Restraints System Sensor for any damage or corrosion.
- Check the sensor connector for signs of damage or loose connections.
- Replace the faulty Restraints System Sensor if necessary.
- Clear the fault codes and perform a thorough test to ensure the issue has been resolved.
Cost to Fix U047E
The cost of repairing the U047E code can vary depending on the specific cause of the issue and the cost of parts and labor. In general, the cost of replacing a Restraints System Sensor can range from $200 to $500, including parts and labor.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
