Where is the o2 sensor on a Mazda 929?

The O2 sensor on a Mazda 929 is typically located in the exhaust system. For most models, you will find one or more sensors positioned either before or after the catalytic converter. Depending on the engine configuration, the upstream sensor is usually near the engine, while the downstream sensor is positioned closer to the rear of the vehicle. Always refer to the vehicle’s service manual for the exact location specific to your model year.
