Code B0078 Saturn Description
The B0078 diagnostic trouble code for Saturn vehicles indicates an issue with the right front/passenger side impact sensor's performance. This sensor plays a crucial role in detecting impacts or collisions on the front right side of the vehicle. When the sensor detects a sudden impact, it sends a signal to the vehicle's airbag system to deploy the airbags and protect the occupants in the event of a crash.
Common Causes of B0078 Saturn
- Faulty impact sensor.
- Damaged wiring or connectors leading to the impact sensor.
- Corrosion or moisture intrusion affecting the sensor's performance.
- Impact sensor out of calibration.
- Issues with the vehicle's ECU receiving signals from the impact sensor.
Symptoms of B0078 Saturn
- Airbag warning light illuminated on the dashboard.
- Airbag system fault displayed on the instrument cluster.
- Airbags not deploying in a collision.
- SRS (Supplemental Restraint System) warning message on the driver information display.
- Diagnostic trouble code B0078 stored in the vehicle's ECU.
How to Fix B0078 Saturn
- Begin by diagnosing the specific cause of the B0078 code using a diagnostic scanner to pinpoint the issue with the right front impact sensor.
- Inspect the impact sensor, wiring, and connectors for any visible damage or corrosion. Replace any damaged components.
- Test the impact sensor's functionality and calibration to ensure it is sending the correct signals to the vehicle's ECU.
- Clear the diagnostic trouble code from the ECU and reset the airbag system.
- Perform a test drive to verify that the airbag warning light is no longer illuminated and that the airbags deploy correctly in a controlled environment.
Cost to Fix B0078 Saturn

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
