B00C8 code meaning
Passenger Seat Occupant Position Sensor B
What B00C8 means
B00C8 marks the second occupant position sensor of the passenger seat. No carmaker publishes it. A position input does not have to look at the person; it can come from how the load spreads over the seat. In a Honda application filed in 2002, a weight unit under each side of the seat carries four strain gauges in a bridge; comparing the front and rear gauge pairs shows whether the occupant sits on the front edge, and comparing the two sides shows a lean to left or right. FMVSS 208 accepts dynamic suppression for the passenger: the bag must already be suppressed when a 3- or 6-year-old dummy moves its head, neck or torso into a zone in front of the cover, a zone each maker defines for itself. Whether B means such a load-based signal is not documented. B00C8 brings on the airbag lamp.
B00C8 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B00C8
- Airbag warning lamp on
- Passenger airbag may be suppressed or released without regard to sitting position
- Safety note: airbag system; disconnect seat sensors only de-energised (ignition off, battery off, wait time), recalibrate after work on the seat, specialist workshop only
Common causes of B00C8
- Most likelyPlug or lead to sensor B damaged when the seat was moved or removed
- PossibleStrain gauge bridge or position sensor B faulty, drifting with temperature
- Less likelySeat frame mounted under tension, so the load split looks implausible
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00C8 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C8 | The exact fault in that area. |
What to do next
- Note B00C8 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.

What does B00C8 mean?
B00C8 means "Passenger Seat Occupant Position Sensor B". B00C8 marks the second occupant position sensor of the passenger seat. It is a generic code, so it means the same on every make.
Is it safe to drive with B00C8?
B00C8 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B00C8 fail an emissions test?
B00C8 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 B00C8 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B00C8 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
