Code U1471 Dodge Description
The U1471 Dodge diagnostic trouble code (DTC) refers to an issue with the left frontal acceleration sensor in the vehicle. This sensor is responsible for detecting changes in acceleration, such as sudden stops or impacts, and relaying this information to the vehicle's electronic control module (ECM). When the ECM receives implausible data from the left frontal acceleration sensor, it means that the sensor is providing inconsistent or inaccurate readings.
Common Causes of U1471 Dodge
- Faulty left frontal acceleration sensor.
- Wiring or connection issues between the sensor and the ECM.
- ECM software or hardware malfunction.
- Impact or damage to the sensor from a previous collision.
- Electrical interference or signal disruption affecting the sensor's readings.
Symptoms of U1471 Dodge
- Malfunction indicator lamp (MIL) or check engine light illuminated on the dashboard.
- Inaccurate or erratic readings on the vehicle's acceleration or stability control displays.
- Issues with the vehicle's airbag system, such as warning lights or failure to deploy in a collision.
- Reduced vehicle stability or handling, especially during sudden stops or maneuvers.
How to Fix U1471 Dodge
- Begin by diagnosing the exact cause of the implausible data received from the left frontal acceleration sensor. This may involve using a diagnostic scanner to read the code, testing the sensor's output, and checking for any wiring or connection issues.
- If the sensor is found to be faulty, it will need to be replaced with a new one. Ensure that the replacement sensor is compatible with the vehicle's make and model.
- Check and repair any wiring or connection issues between the sensor and the ECM. This may involve repairing damaged wires, cleaning connections, or replacing faulty components.
- Reset the ECM and clear the DTC using a diagnostic tool to ensure that the issue has been resolved.
- Perform a test drive to verify that the left frontal acceleration sensor is now providing accurate data to the ECM and that the vehicle's safety systems are functioning correctly.
Cost to Fix U1471 Dodge
The typical repair costs for addressing an issue with the left frontal acceleration sensor can vary depending on the specific cause of the problem and the vehicle's make and model. In general, replacing a faulty sensor can cost anywhere from $100 to $300, including parts and labor. However, if additional wiring or connection repairs are needed, the total repair cost may be higher.

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.
