That depends on the engine, but they should all be either on the exhaust manifold collector or down the exhaust pipe a bit right after the exhaust manifold.

In a 1993 Dodge Eagle Vision, various sensors are located throughout the vehicle. Key sensors include the mass air flow sensor, which is typically found in the intake system, and the coolant temperature sensor located near the engine's thermostat housing. The vehicle also has oxygen sensors in the exhaust system to monitor emissions. Additionally, there may be other sensors related to the anti-lock braking system and the transmission, positioned accordingly.
It appears that the 1993 Isuzu 3.2L V6 engine has just one oxygen sensor. It's a 4-wire type, located at the exhaust Y-pipe outlet. == ==
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
1 on the 2.2
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 sensors are located on the transfercase for your cluster panel
1993 Honda Civic EX's dont have knock sensors.
It is located on the passenger side above the kick panel. With the glove compartment removed it can be seen to the right.
Yes if the engines are the same
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.
There are 2 heated exhaust gas oxygen sensors , 1 screwed into the outlet on each exhaust manifold on a 1993 Ford Ranger 4.0 L .
