Where the 02 sensor on a Mitsubishi mirage?

On a Mitsubishi Mirage, the O2 sensor is typically located in the exhaust system. There are usually two sensors: the upstream (pre-catalytic converter) sensor is found near the exhaust manifold, while the downstream (post-catalytic converter) sensor is located further along the exhaust pipe. Refer to your vehicle's service manual for the exact locations, as they can vary slightly between model years.
