My check engine light came on and I ran the code check with the key since I don't have a meter.
I got a 77 code and a 56 code which I can't find anywhere. The other codes were 12 and 25.
No 55 at the end. It ended with the 56 code. I did it three times to make sure I was not missing something.
any ideas?

 

According to this,

77 is cruise control.
25 is the IAC
12 just means the battery has been disconnected within the last 50 ignition on-off cycles.

Here's an existing thread on 56, which does not exist.

You can always double check by using a scanner instead of reading flashes. Any auto parts store will read the codes for free if you don't have a code reader/scanner.

 

Thank you!
