After more research, I found several dozen Executive Orders on the California ARB web site that define the emissions configurations and requirements for the 2RZ and 3RZ vehicles. It took 8 hours but I managed to distill it into a table
.
Abbreviations:
EO = Executive Order
MFI = Multiport Fuel Injection
SFI = Sequential MFI
EGR = Exhaust Gas Recirulation
O2S = Oxygen Sensor
HO2S = Heated O2S
AFS = Air Fuel Sensor
HAFS = Heated AFS
TWC = Three Way Catalytic Converter
WU-TWC = Warm-up Catalyst TWC
50S = 50 State
CA = California
Notes:
If EGR is blank then the vehicle was not equipped with an EGR system.
If the O2 sensor is followed by (2) then there were two of that type sensor.
If there are two O2 sensors listed than there was one of each type.
If the CAT is followed by (2) then there were two CATs of that type.
If there are two CATs listed than there was one of each type.
If there's a / followed by another digit after the ECM P/N then there was a change during the production run.
If two vehicles have the same EVAP Family number then they have the same EVAP system (I think).
If two vehicles have the same Engine family number then they were certified under the same EO.
and are very similar but not necessarily identical (again I think).
The 2001-2004 EOs did not contain model or ECU numbers (I don't know why).
If I found all of the EOs then the table should contain all models that were sold in California.
The info for models marked 50S should be valid for other states.
Since this info came from the California ARB, there is no info for 49 state vehicles - SORRY!
Finally, I make no warranty that the info is correct. There were some obvious typos in the EOs which I corrected but that also means there might be others which I didn't detect and it assumes that I didn't make any typos myself
