Get down and look under the vehicle and count them.

It does not have 3 catalytic converters. It only has 1.
look under it, depending on state Emission standards you have 1 or 2. one per exhaust pipe out of the engine.
I spent MOST of the day today under my 04 Frontier replacing the throwout bearing. Mine is the 4 cyl.It has one exhaust pipe and one cat in it.

Chuck Blazer was born on 1945-04-26.
There are 2 oxygen sensors on an 04 frontier pickup 2.4litre. One is located after the catalytic converter (on the exhaust Pipe) and the other is between the exhaust manifold and the catalytic converter.
Depends on the year. I have an 04, which has 4 sensors.......2 tapped into the exhaust manifold upstream of the manifold, and 2 in the exhaust pipe below the catalytic converters. If you get the direct fit factory replacements, they just plug right in to the factory wiring harness and screw in to their respective ports. The universal ones have a stupid connector box, for which you have to cut the plug of the old ones and spliceit to the new one which is a pain in the rear. Depends on the year.

How do you reset the computer in a 04 blazer 4.3L
The catalytic converter is located underneath the vehicle in the first half of the exhaust, like a big bulge looking piece
