Hi guys,

I have a problem with my check engine light, it does not work!!
when you starts accord 2004 all light turn on in odometer including the check engine light for seconds then turn off!! but in my car the engine light does not work at all!!

Here is the story:

4 months ago, the check engine light turned on! I took it to mechanical! he told me the catalytic converter need to be changed! he charged me $300 to fix it!! after I got my car the engine light got of, supposed he fixed it!!

after 4 months the car failed in the state inspection!! the reason was a sensor need to be changed and it supposed the engine light went on for that reason!! the inspector told me that the mechanical scammed me and the only thing he did is disconnected the engine light!!!!

My question how to connect it or fix it!! yesterday I opened odometer to change the missing Bulbs!! but I figured out this model has no Bulbs!! there is green board!!

help please!!
