U0473Invalid Data Received From Restraints System Sensor C

  • Generic OBD-II code · Network
How the car detects it
U0473 means the restraints controller receives sensor C but cannot use what it sends. In Chrysler's lists from investigation PE11-019, C is the first left-side satellite acceleration sensor, present already on the four-sensor Wrangler JK; its internal fault is B1B72, while U0172 covers lost contact. On later Jeeps such a side sensor sits in the B-pillar: FCA's STAR case S2108000269 for the 2022 Wrangler answers a B-pillar side impact sensor short (B2761-11) with a check for pinched wiring at the seat belt retractor bracket. Ford's program 22H05 had 2021 Bronco side sensors checked for a missing retaining stud on the B-pillar. A side sensor that delivers bad data can delay the left seat and curtain airbags. Airbag lamp on, no MIL.

Likely causes
