looking for USDM P72 OBD2 ECU P72-A02/3

 

I have one

 

sry looking for version A02/A03 only thnx.

 

Please educate me based upon these two numbers and the C02... What's the difference? They were all on the same car and engine. Just curious for future reference

 

My understanding is that they are slight emissions revisions. Different evap setups, etc.

 

Basically it just means there's a 50 state ECU and a 49 state ECU. (one dealing with california, the others are for the rest of the country).

In all honesty, being that I've lived in California for a number of years with a 49 state ECU, it won't matter. But we'll leave it to the OP.
