WHEN I START ENGINE THE CHECK GAS CAP LIGHT GOES ON AND NOW THE CHECK AIR BAG LIGHT ALSO .WHAT CAUSES THIS AND HOW MUCH IS THE REPAIR -
Answer 1
The check gas cap could be from low pressure reading due to the gas cap not being tightened properly after a fill-up and may go away in time. If not, there is a leak in the vapor recovery system such as a cracked or dislodged vacuum hose or a rusty filler neck. Check air bag light is either a loose wire in the sensors or a failing clock spring on the steering wheel. -
