'94 T&C Van, how to read engine light code?

Hello All.... Anyone care to give me some insight as to how to
retreive the trouble codes from the "check engine light". Can it be
done w/o purchasing a reader. I understand some autos allow you to
count blinks of the car's internal light. Thanks for your help.

To check the computer codes:

With the engine off, switch the ignition key on-off-on-off-on,
leaving it "ON". Do not
go to "start", just "on" during this procedure.

Watch the "Check Engine" or "Power Loss" light. It will turn on, then go
off, then will begin to flash-out any trouble codes that have been stored.
For instance, if it flashes:

flash <pause> flash flash
<long pause>
flash flash flash <pause> flash flash flash flash flash
<long pause>
flash flash flash flash flash <pause> flash flash flash flash flash

Then you have a 12 (one flash followed by two) a 35 (three and five) and a
55 (five and five). 55 means "end of codes" or, if by itself, "No codes
stored. Check the codes and report what you find.

 

Thanks, Dan, will do.

Hi Neil,
Here is a link to a great site that has the proceedure for retreival
plus all the codes and what they mean. I have a 94 Grand Caravan and a 96
Town and country and this has been invalueable:
