93 explorer 02 sensor

[Turdle]

93 question only please

Please state whether yours is California emmisions or not.

Also, how many 02 sensors, that is the important question. You should either have one in the y pipe, or 2, one in each down pipe.
If you can, I would like to know your ECM code

Thanks!!

Not California. Two sensors, one in each down pipe. Don't know the ECM code.

My Ford DSM shows two O2 sensors for California emissions models. Verified against the EECIV connector for the Cali model. Seems to be the same for non-Cali models.

I haven't yet found the ECM part number or anything but I am still looking. I do have access to the pinout for the Cali emissions connector to the PCM and the schematic for the Cali wiring harness.

Some early '93's (build date will be in '92) did still have only one O2 sensor with federal emissions. Every CA and all built after 1/93 that I have seen had 2 sensors.
