They should be in the exhaust system close to the engine ( either in the exhaust
manifold outlets or the
exhaust pipe ) before the exhaust enters the catalytic converters
Bank 1 is the passenger side of the engine and sensor 1 is the upstream sensor
Bank 2 is the driver side of the engine and sensor 1 is the upstream sensor on that side
What else can I help you with?
Where is the upstream o2 sensor on a 2004 ford focus?
Upstream is before the catylitic converter, downstrean is below the cat.
Which way does a Ford 2000 upstream O2 sensor turn to be removed?
Counterclockwise.
Where is the 02 sensors located on 1996 Ford F-150?
On a 1996 Ford F-150, the O2 sensors are typically located in two places: one is positioned before the catalytic converter (upstream sensor) in the exhaust manifold or exhaust pipe, and the other is after the catalytic converter (downstream sensor) in the exhaust system. The upstream sensor helps monitor the air-fuel mixture, while the downstream sensor checks the efficiency of the catalytic converter. Depending on the engine configuration, there may be one or two sensors.
Is the O2 sensor for a 2000 Ford escort upstream or down stream?
both. upstream is under the hood, and the downstream is by the catalytic converter.
Does a 1988 Ford Ranger have o2 sensors?
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
Is there a picture to show the location of an oxygen sensor on 97 ford explorer?
please show me a diagram of the location of all 4 oxygen senors on a 1996 ford explore?
Where is o2 sensor code 1151 upstream bank 2?
bank 2 is the drivers side of the engine on your Ford Expedition sensor 1 is in the exhaust upstream ( before the exhaust enters the catalytic converter )
What is code p1152 on a Ford Expedition?
Lack of upstream heated oxygen sensor switch - sensor indicates rich - bank no. 2
What does an oxygen sensor do in a 1996 ford explorer?
The oxygen sensors located before ( upstream ) of the catalytic converters are used to " sense " the amount of oxygen in the exhaust to adjust the air / fuel ratio for the engine
Where is bank 1 sensor on 2004 Ford Expedition?
Bank # 1 is the passenger side of the engine in a Ford Expedition Sensor # 1 would be before the catalytic converter ( upstream sensor ) Sensor # 2 would be after the catalytic converter ( downstream sensor )
Where is the location on P0153 02 sensor circuit slow responsebank 2Sensor1996 ford exploreror1?
Replace the upstream O2 sensor which is on the exhaust manifold
Where is the bank 2 sensor 1 o2 sensor on a 2000 Ford Expedition?
Bank 2 is the drivers side of the engine in your Ford Expedition Sensor 1 is in the exhaust BEFORE it enters the catalytic converter ( upstream )
