There should be a total of 4 o2 sensors. 2 are located on the exhaust, before the catalytic converter and the other 2 will be after the catalytic converter. The o2 sensors look like spark plugs with wires.

2005 ford taurus running too lean


This would probably be an air leak. Check all engine seams and vacuum lines with the engine running. Take a spray bottle filled with water and when the engine draws in the water spray, the RPM will change.

Where is the o2 sensor on 2005 ford freestar 3.9


o2sensors are located in the exhaust system.you have 4 o2sensors on your car.so you need to know which sensor your looking for.bank 1 sensor 1 is the first sensor in the exhaust pipe on the side cylinder 1 is on.bank 2 is on the side cylinder 2 is on.then you have a sensor before the catalytic convertor and one after the convertor.

Where is the bank 1 sensor 1 on a 2001 ford taurus?


Hello
Bank one is the engine cylinder bank near the engine firewall (see diagram). The bank one sensor one is the Oxygen sensor (O2) located in the exhaust pipe just of the engine cylinder bank at rear and before the Catalytic Converters.

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 79248g01.gif
Fig. 2: Location No. 1 - typical O2sensor located in the exhaust manifold 79248g04.gif
Fig. 3: Location No. 2 - left and right banks of a V-type engine 79248g02.gif
Fig. 4: Location No. 3 - exhaust collector (where more than 1 pipe joins together) 79248g05.gif

2002 Ford Windstar Error Code P1131 And P1151


those two codes are for the o2 sensors. both are the upstream sensors on the front and rear banks. so they are desinagted bank 1 sensor 1 and bank 2 sensor 1. them most common cause for this is faulty o2sensors , bad gas and of a poor running engine. so if your car runs good (no misfire) and gas is ok then replace the o2sensor witch is the very most common cause.
