Question about 1996 Oldsmobile Cutlass Supreme Coupe

1 Answer

I have a 1996 cutlass supreme. The check engine light is on. I have, but not to fimilar with, a OBD2 scan tool. I'm getting the code PO441. (Evaporative Emission System Incorrect Purge Flow). I know this could be a number of things. Where is the best place to start and with what tools do I need? Please answer this question. If I clear my code, the car will run code free for more than a day. If I take my car for the emission test, will it pass during this time? Thanks, Kim S.

What is a scan tool

A scan tool allows for the OBD II (On Board Diagnostics) codes to be read from the engine computer in a car. These are common electronic diagnostics tools used by automotive technicians. They are usually used when a check engine light comes on to determine the error codes associated with the check engine light.

They almost always connect via a standard plug on the divers side under the dash.

Most automotive parts supplier will check a car with complementary service to determine the codes stored in a customers automobile.

What code scanner is needed for a 1994 olds cutlass supreme 3.1?

1994-1995 was a transition year for car makers with the OBD system.
You can do an internet search for each style plug and see which one you have. The scanner will not connect to the wrong plug.
The OBD2 style is tapered on each side. The plug is under the steering column.

I have a 87 two door cutlass with a check engine light that turns on and off. Is there a OBD port in that car for a reader to be conected to trouble shoot the problem

This takes a special scanner called an OBD1 scan tool, so the free tests can't be done, they are for OBD2. The diagnostic port in under the dash. You can do a manual test with a paper clip shorting bar and watching the check engine light flash out the code. Just google that.

I have a 1996 oldsmobile cutlass supreme sl 3.4l and sometimes my car will shake a little and the check engine light will come on and sometimes i will be driveing and when i hit the gas and take off fast...

the flashing check engine light is indicating a misfire. if you can't get it scanned for codes, start with the obvious, check plugs, wires, and coil packs first.
