B0094Center Frontal Restraints Sensor
- Generic OBD-II code · Body
- How the car detects it
- B0094 refers to a single crash sensor placed in the middle of the vehicle front, used where a car has one central frontal satellite rather than a left and right pair. Mitsubishi's airbag unit shows it as CRASH ZONE SENS and adds the J2012 name Center Frontal Restraints Sensor. Its index lists nine subtypes, logged once a fault has persisted for two seconds at ignition on: -11 and -12 for shorts to ground or supply, -88 for an open line, -81 for lost communication, -25 for a failed self-diagnosis, -28 for an offset error, -93 for a reset fault, -55 for a configuration mismatch and -86 when sensor and unit are not the specified parts. That index has no B0090 or B0095, so the centre unit is the only frontal satellite there. Bosch notes that crumple-zone acceleration sensors improve frontal crash detection. The airbag lamp lights.
- What you may notice

- LikelyOpen, short or corroded contact in the harness to the centre front sensor (subtypes -11/-12/-88)
- PossibleInternal fault of the crash zone sensor, e.g. offset or self-diagnosis error (subtypes -25/-28)
- PossibleSensor or airbag unit not the specified part, or unit configuration wrong (subtypes -86/-55)
