locations in the vehicle for air bag and check engine light sensors.

What is your question?

My air bag and check engine lights stay on. The check engine light comes on at will. The air bag light stays on regardless. The only thing I can think of is the sensors are bad. Need to know where to find them.

What makes this problem better or worse?

makes no difference
