A 2001 Mitsubishi Montero typically requires two oxygen sensors: one located before the catalytic converter (upstream) and another after the catalytic converter (downstream). However, the exact number can vary based on the specific engine configuration and emissions system. Always consult the vehicle's service manual for precise information.
Oxygen sensors are located at the same place on all cars cause they all do the same thing: analyze your exhaust gas. It will be on the exhaust pipe, between the engine and the catalytic converter. thats good but there are 3 of them
right in the motor!

i think there is 2

To replace the oxygen sensors on a Mitsubishi 3000GT, first, ensure the vehicle is off and cool. Locate the oxygen sensors, which are usually found on the exhaust manifold and after the catalytic converter. Disconnect the electrical connectors and remove the sensors using an O2 sensor socket or a wrench. Install the new sensors by threading them into place, reconnecting the electrical connectors, and ensuring they are secure.
The oxygen sensor on a 2000 Mitsubishi Montero is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is generally found near the exhaust manifold, while the downstream sensor is located further along the exhaust pipe, before the catalytic converter. Always refer to the vehicle's service manual for precise locations and instructions.
Bank 1 is before the CAT and on the left side (driver side) by the manifold.
towards the middle of thecar installed into the exhaust pipe
You can find them in the exhaust pipe. Depending on engine size you might have anywhere from 2 to 4 oxygen sensors.
I can only find two sensors, engine compartment, pre and post catitytic converter. Ideas, suggestions .......... help, please? Where are the missing two?
To determine which of the four oxygen sensors on a Mitsubishi 3000GT is faulty, you can use an OBD-II scanner to check for any stored trouble codes related to the oxygen sensors. Additionally, you can monitor live data while the engine is running; a malfunctioning sensor will typically show abnormal voltage readings or response times compared to the others. Physically inspecting the sensors for damage, corrosion, or wiring issues can also help identify the faulty unit. Lastly, using a multimeter to test the sensor's resistance can provide further confirmation.
