On a 1999 Subaru Legacy, the heater oxygen sensor is typically located in the exhaust system. Specifically, it is situated upstream of the catalytic converter, usually on the exhaust manifold or the front pipe. This sensor monitors the level of oxygen in the exhaust gases to help regulate the air-fuel mixture for optimal engine performance and emissions control. If you're having trouble locating it, consult the vehicle's service manual for detailed diagrams.
