The 1995 Olds 88 has an obd 2 plug, but is an obd 1 system. Some people call it obd 1.5
There is no option to jump 2 contacts to flash the codes on the check engine light in these cars.
You will either need a compatible scan tool, or a cable to hook to a laptop and the software to pull the codes. (check out
One such scan tool is the Actron CP9185. It has the extra data pin for the 8192 baud communication with the computer in these cars. (pin 9 on the OBD 2 connector)

ALL 1995 and newer cars are OBD2. You cannot retrieve codes with a paperclip anymore. Good luck.

Does the 1994 Olds 88 royale have an OBD port? If so, where is it located?

Almost certain there is a port somewhere but I don't know where but as it is pre-obd2 it could be almost anywhere.

Generic obd2 code readers and scanners mostly won't read obd1 though sometimes will read a small amount. Unless you have a dedicated code reader or scanner there will be no point finding the port - unless the the port can be used to activate a blink code. In that case you will need accurate instructions how to proceed, instructions that will also probably tell you where the port is to be found.
Pre obd2 ports don;t even have to be the now-standard 16 pin type and could be any size or shape.

How do I access the trouble codes on a 1995 Mercury Grand Marquis without a scan tool?

You can access them by going to the link, some late 1995 vehicles were OBD2, then you would have a diagnostic connector under the dash below the steering wheel, otherwise you do it under the hood (OBD1). FORD 1983 1995 OBD1 Decoder

USA anwsers. (outside the USA, 2001 before tools work)
the 1995 sidekick is PRE OBD2, ECU. and is OBD1,
OBD1 prototcal was never published by suzuki so no scan tools work.
period. (over the counter tools)
one reason they went bankrupt here, id bet. like nails in a coffin.
what you do is use the FLASH codes ,just like all cars that era.

here is the full answer, for CEL glowing and driving.

not only can you not communicate, heck , you can even plug the
scan too in. there is no 16pin OBD2 connector on this car.
sorry, nada.

What to do to read codes from check engine light

short answer, bad question! GEN 5 , trecel,
is this a USA,
car,?? gee, why not say that. ????
as each car in each country has different systems. OBD1, OBD1.5 , OBD2, JOBD, EOBD. etc. or worse.....
did you look for the 16pin D-shell shaped DLC connector ? at drivers

so im blocked from being accurate, just that.... alone..
and what engine? 5 engines world wide.... a fact.
2E,3E,4E,5E (new twin cam in 95) or the 1N

in 1995 some engines on some cars were full or 1/2 OBD2 compliant.
that RIGHT, some with 4cyl are OBD1, and V6 OBD2, can prove it.

some cars in 1995, are OBD2 and have no flash codes,
some are compliant to OBD2 with a cable adaptor. 1.5 compliance
the EPA will list this car and non compliant ever if 100% good,
but connector is wrong, or get this, more than 1 meter for steering
so, RTM. the manual never lies, and that manual is , THE FSM.
fact2 the earliest OBD2 is 1994 car. 1996 is mandate.
1995 cars are on LIMBO do your home work. ! or ask ?
to ask answer all questions above, country and ENGINE

Lots of disinformation on the web, i track this and know it.
OMG , 1995.5 year cars, ouch.

ok 1 step at a time.
the light must glow key on, does, ,if not its burned out or stolen
many cars, (vast) the nasty PO stole it so new owners can see truth.
very common. in real world.

short answer 2: can work (USA ONLY)!!!
i found the OBD2 standard, OBD2 connector by right knee.
i jacked in new scan took key on and its dead.
i open hood, look up and see , EPA sticker and no OBD2 compliant word, bingo a OBD1.5 car, ask for help. (custom cable)

tricky huh, i dont design them i only fix them i fix ECU/s

1990 olds 88- the service engine soon light is always on

This car probably doesn't have a obd2 connector. More and likely it is the obd1 which most car part stores wont check. find someone that knows how to take a paperclip to access codes from the service engine soon light. If the light is staying on your "brainbox" sees that one of the sensors is not working to the cars standard. They make a obd1 connector that will plug in and will do the same thing.

I have been trying to retrive the DTC's from my 95 lumina. I tried the OBD-I process, but the MIL did not flash the codes. I bought an CAN OBD-I & II tool, but the reader tells me that the tool is not...

On some 1995 OBD 1 models with a 12-pin Data Link Connector, trouble codes can be accessed by connecting terminal B to terminal A with a jumper wire. With the key in on position, the codes can be read by watching the "service engine soon" light. HOWEVER, some models have a 16-pin DLC and you have to jump terminals 5 and 6 to get the trouble codes to flash.
