DTC B0090 Persistent Airbag Light On in 2014 Honda Accord EX-L After Front Impact Damage
Hello community, I own a 2014 Honda Accord EX-L that suffered a front driver-side collision, resulting in damage to the front fender. Following the crash, my airbag warning light has remained on continuously. Using a DTC B0090 scanner, I detected the fault code: 'No signal from the left front impact sensor'. Upon inspection, I found that both wires leading to the left front impact sensor (located on the radiator core support) were severed—specifically the blue/black wiring. I carefully reconnected them, applied insulation using heat shrink tubing, and replaced the original factory impact sensor with a new one supplied by Honda dealership. I then sent the SRS module for reset, but the DTC B0090 code persists. Attempts to clear the code via scan tool fail completely—the light remains on at all times. I have verified that the driver's side seat belt and buckle are functioning properly (confirmed continuity with 2.7 ohms of resistance), and no issues were found in the seat belt mechanism. Despite these repairs, the DTC B0090 error persists, and the airbag light stays illuminated. The issue appears to be isolated to the left front impact sensor circuit or its associated module communication. Any insights, troubleshooting steps, or known fixes for this specific DTC B0090 code in a 2014 Honda Accord EX-L? Thank you for your help.
thehangarman, Have you found a solution to this issue? I'm experiencing the same DTC B0090 error (my Launch 8001 scanner shows 'No signal from left front impact sensor') in my 2014 Honda Accord EX-L. Both impact sensors were damaged during the crash. I repaired both wire connections using solder and heat shrink, then replaced each with a new factory OEM sensor. However, the DTC B0090 error remains on the left side—my scanner still reports it, and I cannot clear it. I've already had my SRS module reset, replaced the deployed airbag, and repaired the seat belts. The issue seems to be specifically tied to the left front impact sensor circuit. What have you discovered since this post? Any success in clearing DTC B0090 or resolving the persistent airbag light? Your experience would be greatly appreciated! Thanks in advance!
