SERVICE BULLETIN APPLICABILITY: SUBJECT: 1999MY and later Forester 1999MY and later Impreza 2000MY and later Legacy 2006MY and later Tribeca Air/Fuel Ratio Sensor and Oxygen Sensor NUMBER: 11-92-08 DATE: 01/05/09 Introduction This bulletin is for information purposes only. Repair/Service Information When performing diagnostics or reading Diagnostic Trouble Codes (DTC) for Air Fuel Ratio (A/F) sensors and Oxygen (O2) sensors use the following information to identify, locate and repair the appropriate sensor and sensor circuits: (1) Rarely will multiple sensors fail at the same time. (2) On vehicles with only one O2 sensor, the designation for that O2 sensor will be bank 1. (3) On vehicles with only one A/F sensor, the designation for that A/F sensor will be bank 1. (4) Any reference to sensor 1 is an A/F sensor. (5) Any reference to sensor 2 is an O2 sensor. (6) Early PZEV vehicles used an additional O2 sensor behind the rear catalyst and is designated sensor 3. (7) On vehicles with A/F and O2 sensors on the right (Passenger Side) and left (Driver side) of the vehicle, Bank 1 is the right side (Passenger Side) and Bank 2 is the left side (Driver side). Example: DTC P0030 HO2S HEATER CONTROL CIRCUIT (Bank 1 Sensor 1). This DTC is referring to the A/F sensor and since it is on a 2007 Forester there is only one A/F sensor and one O2 sensor. continued... CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS. Subaru Service Bulletins are intended for use by professional technicians ONLY. They are written to inform those technicians of conditions that may occur in some vehicles, or to provide information that could assist in the proper servicing of the vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do the job correctly and safely. If a condition is described, DO NOT assume that this Service Bulletin applies to your vehicle, or that your vehicle will have that condition. Bulletin Number: 11-92-08; Date: 01/05/09 Subaru of America, Inc. is “ISO 14001 Compliant” The international standard for excellence in Environmental Management Systems. Please recycle or dispose of automotive products in a manner that is friendly to our environment and in accordance with all local, state and federal laws and regulations. Page  Example (as illustrated): DTC P0037 HO2S HEATER CONTROL CIRCUIT LOW (Bank 1 Sensor 2). This DTC is referring to the O2 sensor on the right side exhaust (or the O2 sensor of a vehicle with only one O2 sensor) . Refer to the illustrations for more details on locating the appropriate sensors. 2001 - 2004 3.0 Liter Bank 1 Sensor 1 AF Sensor Bank 1 Sensor 2 O2 Sensor Bank 2 Sensor 1 AF Sensor 2005 - Present 3.0 & all 3.6 Liter Bank 2 Sensor 1 A/F Sensor Bank 2 Sensor 2 O2 Sensor Bank 1 Sensor 1 A/F Sensor Bank 1 Sensor 2 O2 Sensor continued...
