EGR valve malfunction ?

Hello 2 all Honda fans and users

I have an 1993, 2.0 liter Accord and my problem is that after the
engine warms up a yellow light turns on in the instrument clusters,
it's an engine on yelow light. I picked up the vaccuum jose from EGR
valve and put a crew into it, because, otherwise my engine refuses to
start when hot. I wonder, is this because of a problem with EGR valve ?
Can anyone tell me what to do and how to check the EGR valve funcition
? Thank a lot !

 

The yellow light is telling you the engine's computer has discovered an
error somewhere in the engine's controls. There will be numerical code
stored in the computer. You need to determine what that numerical code is,
and here's how:
