Code U1470 RAM Description
The U1470 diagnostic trouble code (DTC) refers to "Implausible Data Received From Left Impact Pressure Sensor." This code indicates that the vehicle's onboard computer has detected a discrepancy or inconsistency in the data being received from the left impact pressure sensor. The impact pressure sensor is a crucial component of the vehicle's safety system, as it helps to detect and measure the force of an impact during a collision. When the data from this sensor is deemed implausible, it can lead to issues with the vehicle's safety systems, potentially compromising the effectiveness of airbags, seatbelt pretensioners, and other safety features.
Common Causes of U1470 RAM
- Faulty impact pressure sensor
- Wiring or connection issues
- Sensor calibration error
- Damage to the impact pressure sensor
- Corrosion or debris affecting sensor performance
Symptoms of U1470 RAM
- Airbag warning light illuminated on the dashboard
- Inconsistent or erratic readings from the impact pressure sensor
- Issues with airbag deployment during a collision
- Vehicle may fail safety inspections due to faulty impact pressure sensor
How to Fix U1470 RAM
- Begin by conducting a thorough inspection of the impact pressure sensor, wiring, and connections to identify any visible damage or issues.

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.
