What are the codes p1602 and p1610 ?what do they mean and can you buy the parts.

What is your question?

I found the definition of the codes but no explanation.Can you buy parts to replace them and maybe fix the problem? It is on a 1999 Buick Park Avenue Supercharged.The service engine soon,traction control and Airbag light comes on now,and these were the codes given to me at Orielly's when they plugged into the car's diagnostic port.

What makes this problem better or worse?

Those 3lights stay on in the instrument panel
