LOCATIONS 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 (while cold!) in the general locations to find the applicable O2sensors. NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service. Fig. 1: Location No. 1 - down pipe
Fig. 2: Location No. 1 - typical O2sensor located in the exhaust manifold
Fig. 3: Location No. 2 - left and right banks of a V-type engine
Fig. 4: Location No. 3 - exhaust collector (where more than 1 pipe joins together)
Fig. 5: Location No. 4 - outlet of the catalytic converter
Fig. 6: Location No. 5 - inlet and outlet of the catalytic converter
