NavyBlue99

About a week ago when driving from Houston to Austin about midway I got a check engine light. When I got home and checked the codes there were no current codes. I went ahead and cleared all of the codes out of memory. Tonight I get the check engine light again and here are the codes:

P0332
U1096
U1064
U1016

Now I have looked up the meaning of each of these and realize there is communication loss and a rear knock sensor problem. The strange thing is that each of these codes had a H on the end of them meaning they were history codes. So what does that really mean? Remember I cleared everything out before this happened and only these 4 codes came up. I would have thought anything current would have a C on the end of it, am I correct?

Car is a 1999 Corvette Coupe

Thanks for any help in advance

Disregard the comm codes. The Knock sensor code could be a sensor going bad or a loose wire. Probably a loose wire, since the code popped and went away before.
