Wondering why your MIL doesn't come on?

Ever wonder why your MIL/CES light doesn't come on for certain things?

Misfires, dirty MAF, bad IAC?

Many trucks over 8500lbs only have OBD-I not OBD-II.

Same computer, same communications, but certainly a different threshold for certain things, and other things are just plain gone.

This is from 2001:

In the sheet for 2005, Ford mentions phasing in OBD-II in trucks, and some Federal spec trucks may still be OBD-I.

Because they didn't need to. I guess it's cheaper. Maybe they'd get less emissions warranty claims if certain things that didn't need to be checked on >8500lbs vehicles didn't light the MIL?

I wonder if "functional tests" require certain amounts of circuitry, and if they don't need to do it "by law", then the heck with it?

For instance, functional testing of the IAC - why not? It's probably required in OBD-II, but it would be nice to have in the trucks too.

It's really not good or bad, it's just a difference that must be accounted for when dealing with the heavier trucks.

Since they don't have to meet the stricter emissions requirements of the lighter trucks, Ford just used the same PCM as the lighter trucks but with programming "not implemented" for certain functions.

Bump... good information for all ... explains a lot about why things can go wrong on these motors and never light the MIL.

Fredvon4 has a good reputation on FTE.Fredvon4 has a good reputation on FTE.
The way I read it---- MY 2004 and up have "phased in OBD II" for 8500 lb and higher vehicles

Because of the CAN interface and the massive changes to my cats and evaporative system on the 2005 F350 I believe it is fully OBD II compliant and sensored

1 is gaining momentum as a positive member of FTE.1 is gaining momentum as a positive member of FTE.
Just got to this thread througha link from another post.

One big benefit of this in sttes liek illinois that only test 96 nd newer OBDII vehicles for emissions can be either an eemption if its OBDI?? Or if they can still scan it there re fr fewer codes that cn be tripped and make you fail the test. If im OBDI ill probably stop by the emissions tes station and ask some Qs since its right down the street from me.


My excursion is rated at 88 or 8900 GVWR i gotta try and figure out if its OBDI or II somehow though hummm....

Were the OBDI Equipped trucks sent out of the factory with no rear 02 sensor? That may be a quick way to look under the truck and know what you have.

This explains why in NC I didn't have an emissions test on my '01 F250, just a $8 safety inspection, my wifes van gets a $40 inspection. I guess there are some cost savings on bigger trucks. The other wierd thing I noticed here in NC is that almost all 3/4 ton trucks and larger and alot extended cab 1/2ton trucks have weighted plates, and I don't, never have figured this out.

One thing about inspections is, if you are registered as a passenger car, you WILL fail the test. I had problems EVERY year since I got the thing brand-new in 2002, either because the guy didn't want to put it on his "dyno" emissions equipment, or the thing failed the OBD-II tests. The last test, they just told the inspector to put it in as 8800lbs (instead of the 5700 on the registration) and it needed an idle sniffer test.

But yes, this does effect inspections.

Look under the hood for the emissions sticker. It will say "conforms to XXX for heavy-duty truck engines". My says "Conforms to ULEV specs for heavy-duty truck engines". The key part is "heavy-duty". If it says that, chances are you are OBD-I

The third O2 sensor is NOT an indicator that you are OBD-I or OBD-II. That's just for checking catalytic converter efficiency, and it doesn't mean anything OBD-I vs. OBD-II.
