a 93 tercel which most likey has a the stock 3e-e engine doesnt have an egr system.
You more than likely have a clogged egr port. Remove the EGR valve and clean the ports going to the engine with carb cleaner.
its the hose coming off of the valve cover that's the egr valve
It is probably your EGR valve causing the check engine light. I recently bought a used 1997 Toyota Celica and had this exact problem. The new valve cost approximately $85 and fixed the problem right away.
The egr valve is located on top of the engine. It is close to the firewall, mounted close to the center from side to side.
according to the emissions label it does not have an EGR valve.
