I have a check engine light, need a code reading tool. What type interface does the 2002 E350 with 7.3 diesel use?

And once I have the code, where can I look up what it means?

 

you can look here http://www.dieseltalk.com/support/DTC.pdf
you will have to get one that is for the 7.3 they are not OBDII compliant so AZ cant read them.

 

Wrong.

They are not OBDII compliant so most readers cannot read ALL of the codes. However there are PLENTY of codes that a normal reader can read. Go to an auto parts store and ask them to pull the codes. I have a $50 code reader and every time my CEL has come on it has pulled a code, and it was the RIGHT code each time.

True there are somethings that these hand held ones cant read on these trucks, but all of the basic codes are still there.

Dont immediately throw out the cheap code reader. Its a lot better to go get it read for free and probably fix it than spend $300 on an AE just to know that you have a bad GPCM (That was my CEL code, and my hand held one pulled the code just fine.)

 

OK, good. So on the cheap readers, what type interface - OBDII or other?

Does Oreilly do free code reading for you? Never asked...

 

They are OBDII. Most Oreillys do.

 

ok i did not know that AZ could not read them. i though that it would have to be a scan gauge or AE or superchip to read codes

 

P0113 - air intake sensor high input. Gotta look that up now.

 

OK, let me try to explain why and why not the OBD II readers will and won't work.........

Anything built after 1996 (including some earlier '95) vehicles have to be OBD II compliant. OBD II was a standard that was required to have vehicle builders use a standard set of codes for like items (All O2 Sensors for almost all vehicles will throw the same code this way). There are some rules on GVW that keep vehicles from being OBD II, but most ARE OBD II compliant. The difference comes when the manufacture puts something in the truck that is specific to them (7.3L Powerstroke made by International in a Superduty). They then do not have to meet the OBD II rules which state that vehicles need to share a common code. Since this is only specific to Ford, they can create their own set of codes for the PCM.

With OBD II reader companies wanting to make money with little investment, they only build the readers for the masses. It is too much work or time to invest in a specific market. You can prove this by taking an OBD II reader to any similar year Superduty with a 5.4L or a V10. The codes will pop up like they will on a Toyota Camary. Now if Ford has specific codes to those engines, you may again have a gap.

The 7.3L Powerstroke label on the valve cover specifically states it is not OBD II compliant. That is a fact! The rest of the system will meet the OBD II rules though. That is why the OP can get the code he had pulled and why Trey can pull certain codes. They are commonly shared OBD II codes.

If you want to read more about it, I suggest taking a look here: On-board diagnostics - Wikipedia, the free encyclopedia It is good information and may help clear some questions up.

 

Here is the troubleshooting for your code.

 

^^ that rocks, thanks!
