Code U1470 Chrysler Description
The U1470 Chrysler code indicates that the vehicle's onboard computer has detected implausible data received from the left impact pressure sensor. This sensor is responsible for detecting sudden changes in pressure that could indicate a collision or impact on the left side of the vehicle. When the sensor sends data that is inconsistent or does not align with the expected parameters, the code is triggered.
Common Causes of U1470 Chrysler
- Faulty left impact pressure sensor.
- Damaged wiring or connectors leading to the sensor.
- Malfunctioning onboard computer.
- Sensor calibration issues.
- Previous collision or impact causing damage to the sensor.
Symptoms of U1470 Chrysler
- Illumination of the airbag warning light on the dashboard.
- Inconsistent or delayed deployment of airbags in a collision.
- Loss of power or reduced performance.
- Vehicle entering failsafe mode.
- Erratic behavior of safety systems.
How to Fix U1470 Chrysler
- Begin by connecting a diagnostic scanner to the vehicle's onboard computer to retrieve the specific error codes and confirm the issue with the left impact pressure sensor.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion. Replace any damaged components.
- Test the sensor's functionality and calibration using a multimeter or specialized equipment. Adjust or replace the sensor as needed.
- Clear the error codes from the onboard computer and perform a test drive to ensure that the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the safety system or onboard computer.
Cost to Fix U1470 Chrysler
The typical repair costs for addressing an implausible data error from the left impact pressure sensor can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.

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.
