B1944 is a diagnostic trouble code (DTC) for "Airbag Crash Sensor #1 Ground Circuit Open". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $79.99. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
A B1944 code means that the vehicle’s onboard diagnostic system has detected a discrepancy in the airbag circuit that is consistent with a poor ground on the #1 sensor, and has registered a trouble code.
Airbag systems are designed to perform self-diagnostics. In the event of a B1944 code, voltages are off spec and indicate a poor ground in the system, registering a trouble code as part of the self-diagnostic process.
As with many codes, technicians often jump ahead on a B1944 code without doing a proper process of elimination and end up replacing parts unnecessarily. A poor reference ground can lead to a false B1944 reading, prompting unnecessary repairs.
A B1944 code can result in the airbag not deploying in the event of a collision.
On many Ford vehicles, the air bag warning light will flash to alert the driver to a problem. The light will flash an indication of the code itself. In this case, it would flash four times, followed by a pause, followed by four flashes to denote 44.
Any airbag-related work is complex and might be best left up to a professional. Accidental deployment of the airbag can result in serious injury.
