I have a 94 3zve. The 93 FSM available online only shows one O2 sensor. However, when I search for the part online for my 94 (by VIN Number), it shows one for in front of the converter and one for behind the converter. Are there two?

I believe the california models had two

How do you know if it is a California model? I know it was built in Japan via VIN number.

clime under it and look if it has 2 then u will need 2 if one then just one. also i do think if u look at the vin there is a spot on it that says if its a cali car or not, and its just a number or letter that u have to look at the vin code to see

The truck is out of town; so this is why I am trying to determine whether 1 or 2 sensors. I'll research the VIN number concept. Thx.
