How to Decode Check Engine

A while back I scanned a post that explained how to decode a Check Engine manually without the aid of a decoder. I used the process once at least a year ago and it worked well. Unfortunately, I forgot to write down the steps.

I have a 1994 Plymouth Grand Voyager LE, 3.8L, 6 cylinder. I noticed that when I drive for more than four or five miles above 55 mph, I get a Check Engine.

There are no other symptoms - the car is running great.

I'm suspecting an EGR issue but I would like to confirm. Can anyone refresh my memory on the manual process? I know it involves turning the ignition on and off a number of times and then counting the check engine light flashes, but I don't remember the exact sequence.

Thanks in advance!

Turn the ignition key ON,OFF,ON,OFF,and finally ON again(ENGINE NOT RUNNING)
The codes will start to flash on the POWER LOSS or CHECK ENGINE light.
FLASH,pause,FLASH,FLASH=code 12

You have a OBDII output on your Altima. Bring it to Autozone and they will tell you the codes for free.
