Bosch Oxygen Sensor P/N:16224
Bosch 15025 oxygen sensor for the 2005-2009 Subaru Outback H4 2.5L and other vehicles reads exhaust air-fuel ratio for the ECU. This is the downstream sensor, and its signal helps the ECU hold stable combustion and lower emissions.
An exhaust leak, damaged wiring or a fuel-delivery problem can be behind a check engine light, higher fuel use or a failed emissions test, and so can a worn sensor. Find the cause before buying a new one.
Many vehicles are covered, and the 2004-2007 Subaru Forester H4 2.5L is one of them: this is an oxygen sensor for its downstream position.
