Service air bag came on
So I have a 2010 Chevy impala and my low tire
light came on a few weeks ago and now today my
service air bag came on. I was wondering if my
sensor is bad and if it is does it need to be
changed and if so how much will it cost.
That light will appear when anything in the air bag system has failed or is sending a signa that's out of normal range. Might be a bad sensor, a corroded wire or connection, or you might just have a bad battery. Have this checked.
