I have a 2002 honda civic ex coupe, I found out about the problem when I went to a auto shop to get a state inspection on my car to register it. The car works well and all, but the guy said he had problems connecting his state computer to the obd2 port. I tried connecting it with my generic obd2 scanner, the scanner received power but didnt show any results on O2 sensor info and other details like VIN. I checked the fuse and the wires but I cant reach the back of the port, it’s in an awkward position, can anyone help me with this?
