Where is the 1994 Toyota Celica OBD port location?
I want to diagnose an old 1994 Toyota Celica so that I can figure out what replacement parts I’ll need for repairs. Problem is, I can’t find the plug for the OBD code reader. Where is it?

OBD ports can be tucked away in sneaky places! The 1994
Toyota Celica
OBD port location is underneath the hood on the driver’s side of the engine bay in a black plastic box labeled Diagnosis. When you open the box you’ll see a bunch of pins and a diagram detailing the location of each pin—similar to a fuse box. Nowadays, the OBD port in many cars can be found below the steering wheel near the driver’s side foot well—but those are OBD-2 ports that you can plug an OBD-2 code reader into.
Older vehicles like the 1994 Toyota Celica are equipped with an OBD-I port, which isn’t compatible with the OBD-2 code reader. You’ll still be able to diagnose mechanical problems, you just need a first-generation OBD code reader or OBD-1 to OBD-2 adapter.
