Just played with Proscan 5.2 on my EX and it is OBD1.
Shows only O2 sensor bank 1 and proscan tells me that the vehicle is not ready to
share info for bank2.It will show limited data but half of the Proscan sensors are dead.
It shows bank1 and bank2 fuel metering and they look similar so I guess O2 sensors are working.
Is there a way to exchange PCM-OBD1 with PCM-OBD2,or maybe reprogram it to OBD2?

There is no OBD-II PCM for the 2-valve V10.

It "talks" OBD-II, but isn't "OBD-II compliant".

I'd call Proscan and see what they say.

WOW,
I thought this was an x-rated post or something sick. Ever wonder why your Mother In Law (MIL) doesn't come on. Phew I was scared.

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.
Both KOER and KOEO tests will run on our V10's. This isn't really an OBDII or OBDI thing, and both tests are for the most part system and electrical continuity tests. As far as I know, you need a Ford Scan Tool (NGS, WDS) in order to run these.

Did I read here somewhere that my '03 with "Californica Emissions" was an obd11?

Does it have an O2 sensor after the catalytic converter?

From memory, I don't think so, but it's too crummy to look now. Does that make it obd1?

Pretty much. It can't be OBD-II because it can't check the catalyst efficiency.

MIL = Malfunction Indicator Light

CES = Check Engine Soon

In other words, the light the computer turns on to tell you something's up.

Hi, guys; I said last week that my 03 F350 auto didn't have a sensor after the cat and it is a CA emissions truck. It does. It's a couple feet behind the cat and I never saw it b4. Does that mean my truck has the OBDll?
