U0475 code meaning
Invalid Data Received From Restraints System Sensor E
What U0475 means
U0475 reports corrupt or implausible data from restraints sensor E; U0174 would be the lost-contact code. No manufacturer publicly ties letter E to a mounting point. Chrysler's restraint fault lists in NHTSA file PE11-019 even skip it, jumping from the second left-side sensor D to the first right-side sensor F. A system that uses E needs at least five peripheral crash sensors, and Bosch's compact AB light controller offers no more than six such inputs. The sensors talk over PSI5, a two-wire interface that grew out of airbag satellite links. Airbag lamp on, no MIL.

- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0475
- Airbag warning lamp on
- Code stored in the restraints controller only
Common causes of U0475
- PossibleDamaged two-wire sensor line or connector
- PossibleInternal fault in the satellite sensor itself
- Less likelyRestraints controller coding does not match the installed sensors
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0475 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 75 | The exact fault in that area. |
What to do next
- Note U0475 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0475
What does U0475 mean?
U0475 means "Invalid Data Received From Restraints System Sensor E". U0475 reports corrupt or implausible data from restraints sensor E; U0174 would be the lost-contact code. It is a generic code, so it means the same on every make.
Is it safe to drive with U0475?
U0475 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0475 fail an emissions test?
U0475 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0475 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will U0475 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
