Locating Driver Side Oxygen Sensor

[pkoo]

Anyone have an idea on how to find the driver side oxygen sensor? I was able to trace one from the passenger side and repair it, but I cannot find the second oxygen sensor. I have been told that the 1994 Ford Ranger XLT 3.0L has two oxygen sensors.

Any ideas, pictures, or diagrams?

I don't think the '94 had two. My '93 only has 1.

For Rangers, 89-92 there is 1 before for the catalytic converter.

93-94 there are 2 just downstream of each exhaust manifold.

95-up' There are 2 just downstream of each manifold and 1 after the catalytic converter.

SO, on your '94, there should be two, the driver's side should be in a similar location on the Y-pipe that the passenger side was.

I don't think the '94 had two. My '93 only has 1.

1992 was the crossover year, so the very first '1993' models probably had the same 4.0L and single O2 sensor as the 91-92's, those built later in '92 had the dual O2 sensors like the '93's to go with the slightly improved engine.

On my 94 it was easier to get to the driver side O2 sensor from underneath. There are two, one on each exhaust pipe right after/below the manifolds.
