Code U1471 Description
The U1471 code indicates that the vehicle's onboard computer has detected implausible data being received from the left frontal acceleration sensor. This sensor is responsible for measuring the vehicle's acceleration in the front left side, providing important data for the vehicle's stability control system. When the data received from this sensor is deemed implausible, it can lead to issues with the vehicle's stability control, traction control, and potentially affect the overall handling and safety of the vehicle.
Common Causes of U1471
- Faulty left frontal acceleration sensor.
- Wiring or connection issues with the sensor.
- Corrosion or damage to sensor connectors.
- Software glitches or communication errors within the vehicle's system.
- Faulty stability control module.
Symptoms of U1471
- Traction control light or stability control light illuminated on the dashboard.
- Reduced power or limp mode operation.
- Unusual handling or steering behavior.
- ABS system malfunction.
- Increased stopping distance or decreased braking performance.
How to Fix U1471
- Begin by connecting a diagnostic scanner to the vehicle's OBD-II port to retrieve the specific error codes and data related to the left frontal acceleration sensor.
- Inspect the sensor and its wiring harness for any visible damage, corrosion, or loose connections. Repair or replace any damaged components.
- Clear the error codes from the vehicle's computer using the diagnostic scanner and reset the system.
- Test drive the vehicle to ensure that the warning lights are no longer illuminated and that the stability control system is functioning properly.
- If the issue persists, consider replacing the left frontal acceleration sensor or seeking professional assistance for further diagnosis and repair.
Cost to Fix U1471
The cost of repairing an issue related to the U1471 code can vary depending on the specific cause of the problem and the labor rates in your area. On average, you can expect to pay anywhere from $100 to $300 for 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.
