The screw into the exhaust pipes. One will be near the front under the front of the engine, one will be after the second converter roughly under the passenger seat.
O2 sensors are always located on the exhaust system.
There are two.
There are two.
The oxygen sensors are in the exhaust pipes on most models.
Your Villager has only one O2 sensor located on the front catalytic pipe before the converter. You should be able to look down between the engine and radiator and see it.
The 1993-2002 Mercury Villager typically has two oxygen sensors: one located before the catalytic converter (upstream) and another after the catalytic converter (downstream). These sensors help monitor the engine's air-fuel mixture and the efficiency of the catalytic converter. However, the exact number can vary based on the specific model year and engine configuration.
On a 2000 Mercury Villager, the oxygen sensors are located in the exhaust system. There are typically two sensors: one located before the catalytic converter (upstream) and another after it (downstream). To access them, you'll need to look under the vehicle or potentially remove some components for better visibility. It's advisable to consult a repair manual for detailed locations and procedures.
Both oxygen sensors are in the exhaust pipe, one under the front of the engine, one roughly under the passenger seat are.
I wasn't aware that there was a middle oxygen sensor. I have a 1997 Villager that was vandalized and the catalytic converter and O2 sensors were stolen. From what my mechanic tells me and Auto Zone there are only 2 sensors, one in front of the catalytic converter and one behind it.
There are two oxygen sensors, one in the exhaust near the engine, one in the exhaust pipe after the second converter, roughly under the passenger seat on OBD-II vehicles.
There are two sensors, one in the exhaust pipe at the front of the vehicle, one after the second converter under the passenger seat area.
in the exhaust pipes just before the catalytic converters
