Ok my CEL came on while I was driving on Thursday. Today I checked to see what codes it would give me and it was 05 05. I checked on the CEL decoder and it came up as an invalid code. I went to try again and my CEL light was off now. Will it come back on if the same problem is still there? Could I have just not read the code right and now it won't come back? Or should I just not worry now that the light isn't on anymore?

Thanks!

 

isnt 0505 "No Failure Recorded/Detected" ?

aaaah I see, stupid me, I read this and got worried:

"NOTES:

If the diagnosis is "Undefined" then the error code you entered does not exist.
Redo the procedure and try counting the pulses again.

Thanks for the help!
