OBD 1.5 refers to a partial implementation of OBD-II which General Motors used on some vehicles in 1994 and 1995 (GM did not use the term OBD 1.5 in the documentation for these vehicles - they simply have an OBD and an OBD-II section in the service manual.)
For example, the 94-95 Corvettes have one post-catalyst oxygen sensor (although they have two catalytic converters), and have a subset of the OBD-II codes implemented. For a 1994 Corvette the implemented OBD-II codes are P0116-P0118, P0131-P0135, P0151-P0155, P0158, P0160-P0161, P0171-P0175, P0420, P1114-P1115, P1133, P1153 and P1158.
This hybrid system was present on the GM H-body cars in 94-95, W-body cars (Buick Regal, Chevrolet Lumina ('95 only), Chevrolet Monte Carlo ('95 only), Pontiac Grand Prix, Oldsmobile Cutlass Supreme) in 94-95, L-body (Chevrolet Beretta/Corsica) in 94-95, Y-body (Chevrolet Corvette) in 94-95, on the F-body (Chevrolet Camaro and Pontiac Firebird) in 95 and on the J-Body (Chevrolet Cavalier and Pontiac Sunfire) and N-Body (Buick Skylark, Oldsmobile Achieva, Pontiac Grand Am) in 95.
Depending on the year and the vehicle, a car with the OBD 1.5 system may have either the older OBD-I connector, or the newer OBD-II connector, but they are electrically identical to each other.
The pinout for the ALDL connection on these cars is as follows:
Female OBD connector pinout 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 For ALDL connections, pin 9 is the data stream, pins 4 and 5 are ground and pin 16 is battery voltage.
Additional vehicle-specific diagnostic and control circuits are also available on this connector. For instance, on the Corvette there are interfaces for the Class 2 serial data stream from the PCM, the CCM diagnostic terminal, the radio data stream, the airbag system, the selective ride control system, the low tire pressure warning system and the passive keyless entry system.
An OBD1.5 has also been used on Mitsubishi cars of '95 '97 vintage.
An OBD1.5 has been used in some 1995 Volkswagen VR6's (Juice Box's GTI)

Most common problem causing this code is the purge solenoid. A quick smoke test will show if you have any leaks in the system. If no leaks and the fuel cap is installed properly it's the purge solenoid.

vehicles from 1996 and up have an OBD II computer. The Major problem
when it comes to OBD II is that you can no longer acquire the trouble
codes by counting the flashes of the Check Engine light like you could
on earlier OBD I vehicles. You can take your car into a local
high-tech service shop, where the minimum charge for computer
diagnostics and engine diagnostics might cost you somewhere into three
digits. Or you may want to learn about OBD II systems. in order to do so
you will need an OBD II scan tool. I have already done the research for
you and located several different scan tools for you to choose from. If you already have the code and need to know what it means check out our complete list of OBD II Codes Here.
OBD II scan tools connect to the vehicle's computer through a connector under the dash by the steering wheel.
