1995 Honda Accord Trying to find engine codes using an ohmm

Computer problem
1995 Honda Accord 6 cyl Automatic

Hi,

I drive a 1995 Accord EX and I'm trying to find out why my check engine light is on.

I'm attempting to use an ohmmeter to find the engine code, but I don't even know where to connect it to. Anybody mind pointing me in the right direction?

Thanks.
