Are you wanting to know what this code means, or what it might take to fix the code?

The B2290 is a code related to the SRS (aka airbag) occupant classification sensor. It might be due to a bad sensor, it might be due to a loose/damaged connection, or it might be due to an issue with the SRS control module. Unless you have a scan tool that can access the SRS system to further diagnose this system, you're going to want to take the car to a professional.

Flash code 16 can have several different possible causes.
It is for the Occupant Classification Sensor (OCS) system, as well as the passenger seat belt tension sensor..

Possible causes"
> OCS module internal fault
> OCS module calibration fault
> OCS module sensing element fault
> OCS module communications fault
> Front passenger belt tension sensor circuit fault
You need to pull Process Identifier (PID) codes to know which area to took for the fault.
Flash code 16 can be broken down into a smaller area of possibility with the PID code "B2290" and the symptom code (xx) following.
> B2290(24)
> B2290(25)
> B2290(26)
> B2290(27)
> B2290(29)
> B2290(31)
Getting a flash code 16 can also be a combination of faults that will show up as combinations of PID codes.
