I had my vehicle checked when the air bag light came on and the code B0100, electronic front end sensor fault, appeared. I need to know where to locate the sensor so I can replace it. The truck is a C1500 extended cab 2005 Chevy Silverado. Any help in answering this will be much appreciated.

Your seat has PPS (passenger presence system) sensors on the seat rail controlling the airbag multi-stage deployment and the B0100 diagnostic trouble code indicates a left signal circuit (sensor 1) performance fault. I suggest you check the connector to sensor 1, the occupant sensor on the driver side seat rail, and also check the connector to the SDM (sensing diagnostic module) which is mounted on the floor under the driver side seat. But to prevent accidental deployment of the airbags be sure to disconnect the negative battery cable and the wait at least 1 minute before tampering with the connectors. After checking the connectors for looseness or corrosion, then re-connect the negative battery cable and turn the ignition switch on to see if the airbag light goes off. If it doesn’t then the driver side sensor (sensor 1) is probably defective. But before replacing the sensor, swap the driver side sensor over to the passenger side and the passenger side over to the driver side and then after cycling the ignition switch check the trouble codes again. If you get a B0103 (sensor 2 performance fault) then the sensor is bad but if you still get a B0100 (sensor 1 performance fault) then the problem is likely a faulty connector to the driver side sensor or a problem with the SDM or its connector, the sensing diagnostic module mounted on the floor under the driver side seat. And just as a reminder to prevent accidental deployment of the airbags, be sure to disconnect the negative battery cable and the wait at least 1 minute before tampering with the connectors, sensors, and the sensing diagnostic module.
