★ Top Answer
The Subaru Impreza's bank 1 sensor 1 can be found on the right side of the exhaust system before the catalytic converter. This sensor monitors oxygen levels in the exhaust gases as they leave the engine. Signs that you may have a faulty oxygen sensor include increased fuel consumption, excessive smoke from the exhaust, rough idling, irregular engine performance, stalling, or slow acceleration. A malfunctioning oxygen sensor can affect your engine's timing, combustion process, and other important functions. It is recommended to replace the oxygen sensor every 60,000 to 90,000 miles as it is a part that wears out over time.
