U0472Invalid Data Received From Restraints System Sensor B
- Generic OBD-II code · Network
- How the car detects it
- U0472 points to restraints sensor B: the airbag controller hears it but discards the transmitted values as corrupt or implausible, whereas U0171 would mean silence. Chrysler's NHTSA filing PE11-019 lists sensor B as the right-hand up-front satellite measuring acceleration on its 2007-2008 Jeep models, paired with internal fault B1B71. Front satellites of this kind sit in the crumple zone, where they notice a frontal crash earlier than the central unit. How much depends on their mounting is shown by Land Rover recall N685 for the 2022 Range Rover: front crash sensors fastened below the specified torque could work loose, feed the restraints system wrong information and even cause an unwanted frontal airbag deployment. Expect the airbag warning lamp; no MIL.
