Rather than mechanical bits, the EFI regulates fuel flow using electronic signals. Thus, it created the need to put computers in cars. OBD Scanner II

Types of OBD Scanners

Yet, the CARB failed to issue standards for the systems until the year 1994.  By this time, the standard was referred to as OBD II which was implemented for car models 1996 and onwards. It is safe to say that for the past two decades, the car sold do follow the OBD II standard and each car does have ports for it.
