94 civic with d16y8 motor check engine light code

have you erased the code from your PCM, or have you unplugged your battery too reset the PCM? if you want the engine light too turn off sometimes you have to unplug the battery to do that. if not the issue may lie in the wiring if it is a o2 sensor code, or another issue… first try too unplug the battery from your car or erase the code with a scan tool.
