• Description:

  This genuine Ford side air bag impact sensor is a supplemental restraint system crash sensor that detects the rapid deceleration and intrusion of a side impact and signals the restraints control module to deploy the side air bags and curtain or seat-mounted air bags. Ford catalogs this component as Sensor Side Air Bag. It is a genuinely cross-platform part fitting a wide range of Ford and Lincoln vehicles, including 2009-2014 F-150, 2011-2016 F-250, F-350, F-450, and F-550 Super Duty, 2011-2014 Expedition, 2010-2011 Ranger, 2010-2014 Lincoln Mark LT, and 2011-2014 Lincoln Navigator. It replaces earlier service numbers 9L3Z-14B345-B and AL5Z-14B345-A. Because it is a safety-critical sensor, a fault typically illuminates the air bag warning light and sets a side-impact sensor diagnostic trouble code, and the side restraints may be disabled until the sensor is replaced and the system verified. Owners and technicians replace this sensor when it fails self-test, after a collision that damaged it, or when corrosion or a wiring fault at the sensor triggers an SRS warning. Install with the ignition off and the battery disconnected per Ford restraint-system service precautions, mount the sensor to the specified body location with the connector fully seated, then clear the codes and confirm the air bag system passes its self-check before returning the vehicle to service. Correct orientation and secure mounting are essential for the sensor to read a side impact accurately and protect occupants.
