I got a MIL ['check engine' light method] diagnostic sequence of 12 77 32 32 55.
12 = battery disconnect (not sure why)
77*= ??
32** = ??
32** = ??
55 = end of sequence

The Chilton's manual has a double asterix next the 32**code that suggests the more serious problem over the 77 code. I haven't had a chance to read in detail what the 77 32 means.

What is the causing (source) the 32 and 77 codes??
Will the check engine light shut off if the source of 32** code is repaired?
Are any special tools needed to fix the problem?
The car has 174K miles.I need an emission sticker this month.
I appreciate any help. Thanks!
