what do i do with "malfunction indicator lamp" staying on?
 

i have honda civic automatic, 6 years oldwhat costs roughly should i expect to pay to repair the issue?

Assuming there isn't an actual problem and it is just a matter of the light staying on, remove the fuse from that sensor.

Its telling you theres a bulb out?or not working properly.Check all the bulbs especially the wing ones.Hope this helps
