I Have hyundai sonata 1997
My car shows check engine sign from last 2 weeks..
When I got my car checked.. it said IAS SENSOR CIRCUIT MALFUNCTION..
Does anyone knows what that means.. and how much is it going to cost me?

I really don't have an exact price but I would suggest that you take it to a trusted garage because some can fix one problem and make sure that another problem occurs in a short time to make money.

Try and get quotations from trusted garages and choose the least expensive;)
