The four oxygen sensors are located two in the right exhaust and two in the left exhaust. One is on each side in the exhaust manifold forward of the catalytic converter and one is on each side behind the converter. They can be found easily from under the car. Pass your hand (when the car is cool) along the top of the exhaust if you can't see them. Trace the connecting wires to the wiring harness. Remove the wires from the harness before unscrewing the sensors. The front and rear sensors are not interchangeable as the wiring connectors are different and they work at different temperartures. The removal and installation took me twenty minutes. Don't get the sensor elements dirty.

On a 2005 Mercury Monterey, the oxygen sensors are located in two main areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter) of the exhaust system. The upstream oxygen sensor is typically found on the exhaust manifold or just after it, while the downstream sensor is located on the exhaust pipe after the catalytic converter. Accessing them may require lifting the vehicle for better visibility and reach.
