It is mounted to the throttle body where the air comes into the intake manifold it is round and black and has wires going to it. You may have to remove the air intake tube at the throttle body at the top center of the engine to change it. It has to be adjusted properly make sure you mark the position so you get it back the same spot

The air bag light will remain illuminated if a fault has been detected in the air bag system.
The onboard computer will need to be interfaced with diagnostic equipment to read the fault.
This is also the only way to reset the light.
Good luck, I hope this helped.
