Oxygen Sensor Location

There are different locations in the exhaust system where O2sensors are positioned. The locations have been given numbers and will be used in the accompanying charts to identify the positions of O2sensors in most vehicles.

Due to mid-year production changes or factory inconsistencies, all models may not be covered. If a vehicle being serviced is not covered in the charts, inspect the exhaust system in the general locations to find the applicable O2 sensors.

NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2 sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service.
