The O2 sensors are located on the exhaust of the vehicle. The first O2 sensor will be located beyond the manifold and before the catalytic converter, then there is typically one or more beyond the catalytic converter. to change them you have to unplug the wire at the connecter (generally about 6" from sensor) then simply unscrew them with a wrench out of the exhaust pipe. they may come out hard from repeatedly being heated and cooled.
The oxygen sensors on a 1998 Chevrolet S10 are changed by disconnecting the lead wire and unscrewing them from the exhaust manifold. New sensors are then screwed into place and the wires reattached.
I believe there are 2 oxygen sensors that are used for air / fuel ratio and 2 oxygen sensors that are downstream from the catalytic converters and are called catalyst monitors
On my 1998 Ford Expedition XLT , There are 4 Oxygen sensors. 1 each in front of the Cats. and 1 each behing the cat. for a total of 4 Oxygen Sensors.
How do you change gear oil in a 1998 expedition?"

A 1998 Chevy S10 Blazer has a total of two oxygen sensors. One is used for the upstream and one for the downstream.
You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
i think there is 2
All oxygen sensors are located in the exhaust system.
The oxygen sensors on all vehicles are uasually located before and after the catalitic converter to monitor your emisions ! Good Luck !
You can not bypass it. The oxygen sensors are required for a proper running engine.
It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.
In front of and behind the catalytic converter.
There are 2 Oxygen sensors. One is on top of the catalytic converter called the upstream and the other is at the bottom of the catalytic converter called the downstream.
Theres four o2 sensors in this particular bmw. Two before and two after the cat converters.
( 6 quarts ) with engine oil filter change ( according to the 1998 Ford Expedition Owner Guide )
O2 sensors are always located on the exhaust system.
i believe four,before and after the cat converters
2, one before and one after the catalytic converter
4. 2 pre cat, 2 post.
You will find them in the exhaust system.

Oxygen sensors simply unplug and screw out. They may be a little difficult to reach, and are usually well rusted in place, but there is nothing mysterious about removing them.
