got error codes 14,27,52 and what the heck is 55???

[kmn5]

pulled the error codes from the diagnostic port today to see what's causing the stalling that started fri night.

wasn't expecting code 14
I knew I'd get code 27 for have no cat
not sure about 52, konck sensor does that mean I'm getting bad knock now??

I have NO idea what 55 is, it's not listed on the toublecode
page at http://www.troublecodes.net/Toyota/


got
14, Ignition signal
27, sub oxygen sensor signal
52, knock sensor signal
55 ?????

anyone?
thanks
Ken
