B0079:05 Code - Driver Seat Position Sensor Circuit High Voltage or Open
Quick Answer
The B0079:05 diagnostic trouble code (DTC) indicates that there is a problem with the driver seat position sensor circuit in a vehicle. Common causes include Faulty sensor: The driver seat position sensor itself may be malfunctioning, leading to incorrect readings or a high voltage signal, Wiring issues: Damage or corrosion in the wiring harness connected to the sensor can disrupt the electrical signals and cause a high voltage or open circuit, Loose connections: Loose or disconnected electrical connections between the sensor and the ECU can result in a faulty signal being sent. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B0079:05 Description
The B0079:05 diagnostic trouble code (DTC) indicates that there is a problem with the driver seat position sensor circuit in a vehicle. This sensor is responsible for determining the position of the driver's seat and ensuring that it is in the correct position for safety and comfort. When the sensor circuit detects a high voltage or an open circuit, it means that there is a malfunction in the sensor system. This can lead to inaccurate seat positioning, which can compromise the driver's safety and comfort while driving.
Common Causes of B0079:05
- Faulty sensor: The driver seat position sensor itself may be malfunctioning, leading to incorrect readings or a high voltage signal.
- Wiring issues: Damage or corrosion in the wiring harness connected to the sensor can disrupt the electrical signals and cause a high voltage or open circuit.
- Loose connections: Loose or disconnected electrical connections between the sensor and the ECU can result in a faulty signal being sent.
- ECU malfunction: A problem with the vehicle's electronic control unit (ECU) that receives signals from the sensor can also trigger this code.
Symptoms of B0079:05
- Inaccurate seat positioning: The driver's seat may not adjust properly or may move unexpectedly due to the malfunctioning sensor circuit.
- Warning light on dashboard: The vehicle's dashboard may display a warning light indicating a problem with the driver seat position sensor.
- Unusual noises: The seat adjustment mechanism may produce unusual noises or vibrations when attempting to adjust the seat position.
- Loss of seat memory settings: If the vehicle has seat memory settings, they may not work correctly due to the sensor circuit issue.
How to Fix B0079:05
- Diagnosis: Begin by using a diagnostic scanner to retrieve the specific fault codes and pinpoint the issue with the driver seat position sensor circuit.
- Inspect wiring and connections: Check the wiring harness and connections for any damage, corrosion, or loose connections that may be causing the problem.
- Test the sensor: Test the driver seat position sensor itself to determine if it is functioning correctly or needs to be replaced.
- Replace sensor or repair wiring: Depending on the findings, replace the sensor if it is faulty or repair any damaged wiring and connections to resolve the circuit issue.
- Clear fault codes: After completing the repair, clear the fault codes with the diagnostic scanner to reset the system and ensure that the issue has been resolved.
Cost to Fix B0079:05
The cost estimate for repairing a B0079:05 code related to the driver seat position sensor circuit can vary depending on the specific cause of the issue and the labor rates in your area. Generally, replacing a faulty sensor or repairing wiring connections can range from $150 to $400, including parts and labor. Keep in mind that diagnostic time and labor rates at auto repair shops may vary, with hourly rates typically ranging from $80 to $150. It is recommended to consult with a professional mechanic to get an accurate estimate based on your vehicle's make and model.

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.
