Question about 1994 Oldsmobile Ninety Eight

1 Answer

Cant get reading from the OBDII port

I tried connecting 2 different obd2 readers to the port and both indicate that they cannot access the on board computer to retreive the error codes. Could this be a blown fuse? The cig liter works. Is it possible to get these codes from the dash screen? This car has been serviced only at the dealership, thruout its life, so they must have been able to read the codes. At one time the car had a remote starter connected, could this have messed it up?
The car is lacking power at speed (after the engine light comes on) while on the highway at 50mph for a short period. If I back off the throttle, I can get response up to 40mph, but if I depress the pedal further, it bogs out. Eventually the power comes back a bit and I can run the car but if it down shifts in passing gear, no power again. Now it is begining to skip at idle, sometimes. When I begin moving from a stop, it shudders a bit. This problem has become progressively worse over time, Thanks for your help.

It sounds like the fuel pump is starting to give up. have a pressure check done to confirm. as far as the obd II port just try checking all of your fuses, its not always the lighter fuse

Do you need a certain type of obd reader for a 97 olds achieva? Used an inexpensive obd2 reader but it failed to communicate.

Not all readers are created equal. It all has to do with how they interface with the on board computer system, it is called "protocol" Make sure you get a reader that is listed as being able to read 1997 GM system fault codes. You can also go to any Autozone and have them read your codes.

How to access trouble code

year vehicle manufactured? if 1996 & later, OBDII scanner to be plugged into a port (typically, should be near the steering column, under the dash).
older models may have OBDI (no standard location of port) scanner specific to the make of the vehicle. search the web, on how to read manually (or without scanner) the code by counting the number of blinks of the MIL (malfunction Indicator light) (aka check engine, or service engine soon).

How do i use use the onboard dianostics on 2003 impala?

You need to plug an OBDII code reader into the diagnostic port - under dash board near steering column - and then retrieve the codes, using the code reader as per owners manual. The codes can then be read from the OBDII reader and looked up in the manual to see what they refer to. Let me know if this helps. Thanks.

My 1997 chevy blazer failed inspection because the obd is malfunctioning. I'm trying to find the location of the on board computer to see if I can swap it out myself. I would really like to stay away from...

The OBDII / OBD2 connector is 18" from the center of the center console.


You will need to purchase an OBDII scanner/reader to read these codes.

The alternative method is get a OBD2 cable and a laptop + software to pull the codes.

An inexpensive OBD2/CAN bus reader around $75-$120 is a good start.

Did the inspector mention anything about drive cycle or lack of stored readyness fields?

Please email on why it fail. You can append more info by click the button on TOP RIGHT of this page.

The code reader connected to the computer box link is not reading. i used three different code readers with no reading. the check engine light is on. the vehicle is a 1995 Nissan 200sx SE,...

On these models there are 2 ALDL's. 1 is a Nissan 2 adapter and the other is a OBD2 adapter. Chances are you will need to use the specific Nissan adapter to gain access.

Connecting code scanner to 2007 chry 300 & 95 dodge 1/2 ton ram

Most obd2 connection ports are under the driver side dash and can be visible without removing any panels. On some chrysler Daimler vehicles you do have to remove a panel to access this service port. If its not located under the dash then it will be located under the hood on the driver side and be capped off and labeled obd2 scan tool service. Simply plug your wire in with the key on and the engine not running and read the codes from your vehicles on board computer/ecm/bcm. Hope this helps. Good luck.

Trying to read check engine light on my 95 sunfire it has a obd2 plug but the obd2 tester wont read my codes how can i test this with out going to dealer?

Most consumer available scanners read OBDII on 96 or newer vehicles. If your car does in fact have a OBDII plug then all you need is the software in your scanner to be able to read OBDI codes...a 95 is running OBDI. Advance Auto or Autozone might have a OBDI compliant scanner for free...just tell them you have the OBDII port so they don't take up all your time digging for the adapter!
