A catalytic converter is important in breaking down the fumes that your vehicle creates so that they are safer for the environment. They can cost as little as $40.00 depending on your type of vehicle.
There are 2. One in front of catalytic convertor and one behind the catalytic convertor.

No, it must be replaced.
After the catalytic convertor. Sensor one is before the convertor.

My Chilton repair manual engine wiring schematic, for the 1996 Ford Explorer with a 4.0 L OHV engine shows 3 . Two are upstream (before the catalytic convertor) and one downstream (after the catalytic convertor - which is an oxygen sensor but is used to monitor the efficiency of the catalytic convertor)

"How much is the cost of the Catalytic converter on a 1997 Nissan truck?"
Bad catalytic convertor(s) is a possibility.
Just had my 2004 grand marquis convertor replaced (making an aweful noise). it cost me $250 for the part and then labor etc. total of bill for installing etc was $472.61.
On the 3.0 L and 4.0 L there are 2 oxygen sensors at the front and 1 oxygen sensor (which monitors your catalytic convertor efficiency) at the back after the exhaust gasses have passed through the convertor. On the four cylinder engine - 1 oxygen sensor at the front - 1 oxygen sensor at the back (downstream of catalytic convertor - monitors catalytic convertor efficiency) Helpfull
