87 Camry check engine light On question about what makes light come on?
 

Hello,
I have a 87 Camry 2.0 5 speed with 169k on it. The car has a check engine light that comes on after a few minutes of driving it seems to be on a timer as it comes on after a couple of minutes not right away. I need some help here as this is a older car. What makes/triggers the check engine light to come on in a 87 Camry and what can I do to find out what is the problem? Also I might add I saw a diagnosis plug near the battery under the hood I was wondering where can I get a device that will plug in there and let me know what the light means? I guess I should 1st ask do they make a device like that for such a older diagnosis system on that car?
Also is there a code system on that car like on my Honda where I can find out what that engine light means? Thanks so much for the help as I have no clue what to do 1st here or how to find out what is going on.

you should just get it checked with a diagnosis tool, because a check engine light can come on for numerous reasons.
