To determine which O2 sensor is faulty, you can use an OBD-II scanner to check for error codes that specifically identify the malfunctioning sensor. Common codes like P0131-P0138 will indicate issues with specific sensors. Additionally, symptoms like poor fuel economy, rough idling, or a failed emissions test can also suggest a bad O2 sensor, but a diagnostic scan is the most precise method.
