B0094 — Center Frontal Restraints Sensor

Generic OBD-II · all makesBody

Code B0094 indicates a fault in the center frontal restraints sensor circuit, which monitors impact forces for the front airbag system. The restraint control module has detected an open, short, or out-of-range signal from this sensor.

Symptoms

What causes it — most likely first

1. Failed center frontal restraints sensor

The sensor itself may have an internal open or short circuit, or its sensing element may be damaged.

2. Wiring harness damage or corrosion

The sensor circuit wiring may be cut, chafed, or have corroded connectors causing high resistance or open circuit.

3. Poor connector contact at sensor or module

Terminals in the sensor connector or restraint control module connector may be loose, bent, or contaminated.

4. Restraint control module internal fault

The module's sensor input circuitry may have failed, though this is less common than sensor or wiring issues.

How it's diagnosed

  1. Retrieve all restraint system codes and freeze-frame data with a scan tool.
  2. Visually inspect the sensor, its wiring harness, and connectors for physical damage or corrosion.
  3. Check sensor circuit resistance and continuity between the sensor and restraint control module per service specifications.
  4. Test sensor output signal (if applicable) while simulating a known good condition or using a sensor simulator.
  5. If all wiring and sensor test good, evaluate restraint control module for internal faults before replacement.

Frequently asked

Does B0094 mean the airbag will not deploy in a crash?

The restraint system typically disables the affected airbag deployment loop when this fault is active, so the center frontal airbag may not deploy as designed.

Is it common to replace the restraint control module for this code?

Module replacement is rarely needed; the majority of B0094 repairs involve the sensor itself or its wiring. Replace the module only after sensor and circuit tests confirm it is the cause.

Can a minor front-end collision set B0094 without deploying the airbag?

Yes, an impact below the deployment threshold can damage the sensor or its mounting, storing the code without airbag deployment.

Will clearing the code fix the problem?

Clearing the code only turns off the warning light temporarily; the fault will return if the underlying sensor or circuit issue is not repaired.
