Can anyone tell me it there is a way to read trouble codes on a 2002 E-350 without an analyzer ? I have a check engine light burning on my dash and would like to get a head start before I take it to the dealer.

Thanks

Go to an auto parts store (Autozone, etc.) and ask them for an OBDII Code Reader. This is an electronic device that reads the onboard computer codes and allow you to reset the errors (thus turning the CHECK ENGINE light off). Many auto parts stores loan these for free..you have to put down a deposit which is refunded when you return it. Ask the person that you get the reader from to tell you where the port is to plug it in. It is usually under the dash on the driver's side.

You may also want to pick up a Chilton or Haynes manual for the vehicle while you are there. They cost about $20 and have pretty good error code troubleshooting guides in them.

 

Do what M@tt says. My Autozone guy will just grab his scantool and read out the error codes and reset the light. If the light stays off for a few days of driving, you are set.

If not, sometimes looking up the error code for its description will point right to the problem. If not, I think you need the Ford shop manual. There are debugging charts in there for every error code. They may seem difficult to follow and even shop guys don't like to follow them but in my experience they will lead you right to the problem. Sometimes googling the error code will tell you what others have done to track down he problem.

I don't think the Chilton's or Haynes have those charts but I haven't looked at one in years. I bought the Ford CD for my 1999 ($100 I think) and have used the charts many times.

Note, the Ford CD assumes you have the full Ford scantool. That costs many K dollars. It will say read the voltage at xxxx. The Ford scantool can do that via the computer in the vehicle. You have to find a convenient test point to get the same reading with a voltmeter.

You won't be able to solve the most intracate problem without the Ford scantool but I have been able to fix 10 or 15 different problems with just the CD charts, meter, and brain.

Good luck.

 

A quickie--- If the light came on shortly after fueling the vehicle , a fuel cap that is not tight will cause the lite to come on. It's a quick check and doesn't cost you anything. hanky
