Does anyone know of a site that will show what Vehicles were OBD2 and what year they started?? I know 1996 on some I was hopeing to find a site that Listed them! Thanks

 

It was all light-duty vehicles from 1996-on. Trucks are a little bit in the gray area, as the F250 and larger may not have had it. I thought I heard the LD F250s did, but the F250HD and heavier didn't.

The following has been extracted from the OBD-I and OBD-II Overview section of the Powertrain Control/Emissions Diagnostic Manual from the 4/2005 Service Information as provided by Ford. I'm leary on the 1994 statement; I've always heard that 1996 was the federally mandated year and I know some models of Fords implemented OBD-II somewhere along the way in 1995 (transition year). Maybe a Ford Tech will come along and clarify. I hope this answers a few questions:

------------------------------------------------------------------

Starting with the 1994 model year, both CARB and Environmental Protection Agency (EPA) mandated enhanced OBD systems, commonly known as OBD-II. The objectives of the OBD-II system are to improve air quality by reducing high in-use emissions caused by emission-related malfunctions, reducing the time between the occurrence of a malfunction and its detection and repair, and assisting in the diagnosis and repair of emission-related problems.

North American OBD-II/Federal OBD requirements apply to:

Gasoline engines: All California (CA), Massachusetts (MA), and New York (NY) Federal passenger cars, California, MA, and NY Medium Duty Passenger Vehicles (MDPVs) and trucks up to 14,000 lbs. GVWR (Gross Vehicle Weight Rating). Federal trucks from 8,500 lbs. to 14,000 GVWR will begin phasing in OBD-II starting in the 2004 model year. Federal heavy-duty trucks up to 10,000 lbs. GVWR choosing to certify using Light Duty Truck provisions must comply with OBD-II requirements. Federal heavy-duty trucks over 8,500 lbs. GVWR that do not comply with OBD-II regulations must comply with OBD-I in order to meet minimum Ford serviceability requirements. Passenger cars and trucks sold in Canada and Mexico have Federal calibrations, unless unique calibrations are certified for Mexico at high altitude.

Diesel Engines: All passenger cars and California trucks up to 14,000 lb. GVWR. Federal trucks from 8,500 lbs. to 14,000 lbs.GVWR will begin phase in of OBD II starting in the 2004MY.

Alternative fuel vehicles (AFV): Ethanol/methanol AFVs must meet full OBD-II requirements during operation on all fuels. Bi-fuel NGVs/LPGs are required to meet full OBD-II requirements while operating on gasoline. Dedicated NGVs and bi-fuel NGVs/LPGs are required to partially meet OBD-II requirements while operating on gaseous fuels.
"Green States" are states that choose to adopt California emission regulations. National Low Emission Vehicle (NLEV) is a vehicle required to compliance with California OBD-II, including the 0.020" evaporative system monitoring requirements. Both the NLEV and "Green States" receive California vehicles for all passenger cars and trucks < 6,000 lbs. GVWR. "Green States" are: MA, NY, VT and ME. NLEV states are: VA, CT, RI, MD, NJ, PA, DE and Washington DC.

 

some import cars were obd2 compliant in 1994.

 

My 95 T-Bird is OBDII, and I think 94 is too. They had the 4.6.

I guess it is OBDII, it has the big plug under the glove box that the scanner will read.

Thanks all! Very Good Info as usual I come to this site to find out what I need! have a Good Holiday!
