Upstream is before the catylitic converter, downstrean is below the cat.
cooling sensor for 2004 ford focus zts radiator
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 )
Check the throttle position sensor
The O2 sensor on a 2004 Ford Taurus is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is located on the exhaust manifold or just before the catalytic converter, while the downstream sensor is found after the catalytic converter. You may need to lift the vehicle for better access, especially to the downstream sensor.
Where is the coolant temperature sensor on a 2001 ford focus?" Where is the coolant temperature sensor on a 2001 ford focus Where is the coolant temperature sensor on a 2002 ford focus
It is located before the Calaytic converter
Counterclockwise.
Bank 2 is the drivers side of the engine on your 2004 Ford F-150 Sensor 1 would be in the exhaust before the catalytic converter ( upstream ) Sensor 2 would be in the exhaust after the catalytic converter ( downstream )
both. upstream is under the hood, and the downstream is by the catalytic converter.
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
Only two, upstream and downstream.
Bank 2 is the drivers side of your engine in a Ford Explorer Sensor 1 would be close to the engine before the exhaust enters the catalytic converter ( upstream sensor ) Sensor 2 ( also called a catalyst monitor ) would be in the exhaust after the catalytic converter ( downstream sensor )
