1987 supra code 22 and 51
 

I suddenly have a code 22 and 51 and my 1987 non-turbo supra is running a little rough. The codes seem unrelated, but what would cause both to come on at the same time? I disconnected battery for 5 minutes and got both codes again with check engine light on.

i had the same code not ten minutes ago but it runs fine it was running fine i shut it off and just kiss the key it wouldnt hit so i held it over and nothing ran super monitor code 11 came up disconnected the battery then a 51 all i found was somehow i over heated the main relay under the hood took it out let it cool and she fired right up after that. But i think the 51 can be caused by trying to start it with pedal down some
