Is my 1994 OBD1 or OBD2
I want to replace my O2 sensors with O2 simulators and I though my car was OBD2 but everything I read says OBD2 is 96 or newer. Can someone tell me what it is? Thanks

For all practical purposes the 94 is a OBD 1 system. But it does use the OBD2 ALDL connector. A OBD2 code reader will not work if you hook it up.
Even though the system is an OBD1, it has some imbedded OBD2 codes but you need something like a tech1 to read them and then I don’t know how beneficial it would be any way.
I would just forget about the OBD2 for the 94 and make life simple. You will be very hard pressed to find a OBD1 code reader with the OBD2 connector, but they are around. But on the brighter side, the on board diagnosis to get the codes works very well and will give you more information than most ordinary code readers. Like the CCM codes and EBTCM (brake) codes. Learn how to use the on board well and you will be doing good.
