Code B1745 KIA Description
The B1745 code for KIA vehicles indicates a fault with the Pressure-Side Impact Sensor Front Passenger. This sensor is crucial for detecting impacts on the front passenger side of the vehicle, particularly during a collision. When this sensor is defective, it can significantly impact the vehicle's safety systems, particularly the airbag deployment system. In the event of a collision, the sensor may not accurately detect the impact, leading to potential airbag deployment failures or delays, which can increase the risk of injury to the front passenger.
Common Causes of B1745 KIA
- Impact damage: The sensor may have been damaged due to a previous collision, causing it to malfunction.
- Electrical issues: Wiring harness or connector problems can also trigger this code, interrupting the communication between the sensor and the airbag control module.
- Sensor failure: Over time, the sensor may simply fail due to wear and tear, leading to a defect.
- Corrosion: Exposure to moisture or corrosion can also affect the sensor's performance, triggering the B1745 code.
Symptoms of B1745 KIA
- Airbag warning light: One of the most common symptoms associated with a faulty pressure-side impact sensor is the illumination of the airbag warning light on the dashboard. This indicates a problem with the airbag system and should be addressed immediately.
- Delayed or non-deployment of airbags: If the sensor is not functioning properly, it may not trigger the airbags to deploy in the event of a collision, putting the front passenger at risk of injury.
- Inconsistent airbag deployment: A defective sensor may cause the airbags to deploy unexpectedly or inconsistently, posing a safety hazard to the occupants.
- Erratic behavior of other safety systems: A faulty pressure-side impact sensor can also affect other safety systems in the vehicle, such as seat belt pretensioners or stability control systems.
How to Fix B1745 KIA
- Diagnose the issue: The first step in addressing the B1745 code is to diagnose the exact cause of the fault. This may involve using a scan tool to read the code and inspecting the sensor and its wiring for any visible damage.
- Replace the sensor: If the sensor is found to be faulty, it will need to be replaced with a new one. This may involve removing interior trim panels to access the sensor location.
- Check wiring and connectors: Inspect the wiring harness and connectors for any damage or corrosion. Repair or replace any damaged components as needed.
- Clear the code: Once the sensor has been replaced and any wiring issues addressed, the code can be cleared using a scan tool to reset the airbag system.
- Test the system: After the repair is complete, it is crucial to test the airbag system to ensure that the sensor is functioning correctly and that the airbags deploy as intended in a controlled setting.
Cost to Fix B1745 KIA
The cost of repairing a Pressure-Side Impact Sensor Front Passenger defect can vary depending on the make and model of the vehicle, as well as the specific cause of the issue. In general, the cost of a new sensor can range from $100 to $300, depending on the brand and quality. Labor costs for this type of repair can range from $100 to $300, depending on the shop's hourly rates and the complexity of the repair. Overall, the total cost of addressing the B1745 code could range from $200 to $600, including parts and labor. It's important to note that these are rough estimates, and actual costs may vary based on individual circumstances.

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.
