What OBD code is it?

Depending on the seat option, there is also a pyrotechnic device in the headrest. I know the "comfort seats" had that in 2006 because I have that in my car.
There is a pyrotechnic device in the seat belt tensioner that pulls it tight in a crash.

Not sure what "front passenger side sensor" might be referring to.
