B0114 — Right Front Side Impact Sensor Circuit Fault

Severity: medium Drive with care, to a shop

What B0114 means

The SRS control module constantly monitors the side impact sensors (accelerometers or pressure sensors) in the right front door or pillar and checks their circuits. B0114 is set when the signal or circuit resistance of the right front sensor is out of range. While the fault is active, the system may disable the side airbag and curtain on that side.

Symptoms

  • SRS or airbag warning light on or flashing
  • Airbag system fault message
  • Right side airbag may be disabled by the system
  • Code returns after being cleared

Possible causes

  1. Failed right front side impact sensor in the door or pillar
  2. Damaged or chafed door wiring harness, especially in the hinge boot
  3. Loose or corroded sensor connector
  4. Open circuit or short to ground or power in the sensor wiring
  5. Post-collision repair with an incorrect or improperly installed sensor
  6. Rarely, a faulty SRS module

How to diagnose

  1. Scan with a tool that reads SRS codes and record all codes and freeze frame data
  2. Ask about recent work: door panel removal, seat service or collision repair
  3. Inspect the sensor connector and harness in the door and pillar for damage, moisture and corrosion
  4. Confirm the connector is fully seated with no bent or corroded terminals
  5. Measure circuit resistance and check for shorts to ground or power (disconnect the battery and wait the time the manufacturer specifies)
  6. Check the sensor mounting, orientation and part number
  7. Swap in a known good sensor, clear the code and see if it returns

Common fixes

  • Repair or replace the damaged section of wiring harness
  • Clean or replace the sensor connector
  • Replace the right front side impact sensor
  • Reinstall the sensor correctly with proper torque and orientation
  • Replace or reprogram the SRS module if it is the cause

Questions and answers

What does B0114 mean?

It indicates a fault in the right front side impact sensor circuit. The SRS module is not getting a valid signal from the sensor and turns on the warning light.

Can I drive with B0114?

Yes, the car will drive normally. However, side protection on the right may not work in a crash, so don't put off the repair.

Can I just clear the code?

You can, but it will come back if the cause remains. Find the wiring fault, poor connection or failed sensor.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
