B0092 code meaning
Left Side Restraints Sensor 2
What B0092 means
B0092 belongs to the second crash sensor on the left side. Mitsubishi fits it at the left B-pillar and lists it as B-PILLAR SAT SEN LH, adding the J2012 title Left Side Restraints Sensor 2; its index shows only subtype -55, set two seconds after the unit finds that its stored configuration does not fit the vehicle. A pillar position suits an acceleration satellite: Bosch mounts these on stiff members such as sills, seat cross members or B- and C-pillars, and its SMA773 chip measures two axes up to 60 g and talks to the module over a two-wire PSI5 link. GM-built Saabs use the number differently: the 2006 9-5 and the 9-3 store B0092 for a general fault of the passenger presence system, with the airbag system then rated out of order. The airbag lamp is on.
B0092 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B0092
- Airbag warning lamp on
- Left side impact detection rests on the remaining sensors only
- Safety note: airbag system; disconnect the battery and keep the wait time before removing pillar trim, work at a specialist workshop
Common causes of B0092
- Most likelyAirbag unit configuration not matching the fitted sensors (Mitsubishi subtype -55)
- PossibleLoose or corroded plug at the B-pillar sensor after trim or body work
- PossibleOn GM-built Saabs, passenger presence system fault (different meaning)
- Less likelyInternal fault of the B-pillar satellite sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0092 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). |
| 92 | The exact fault in that area. |
What to do next
- Note B0092 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.
