( sensor 2 would be after the exhaust has passed through the catalytic converter , also called the downstream sensor or catalyst monitor sensor )
where is bank 2 sensor 1 in a 2001 ford taurus ses 6 cyl
The bank 1 oxygen sensor on a 2003 Ford Taurus is located on the motor. It is on the top, back part near the firewall.
Bank 2 is the drivers side of the engine in your Ford Explorer Sensor 2 is after the catalytic converter ( downstream )
Bank 1 is the passenger side of the engine ( V6 and V8 ) in a 2001 Ford Explorer Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
bank 2 is the drivers side of the engine and sensor 2 is downstream of the catalytic converter
On a 2001 Ford Mustang , 3.8 liter V6 engine : Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
Bank 2 is the driver side of your engine ( V6 or V8 ) on your Ford F-150 Sensor 2 is after the catalytic converter ( downstream )
Trouble Code P1151 means:Lack of HO2S bank 2,sensor 1 switches,sensor indicates lean
On a 2003 Ford Taurus, the bank 2 oxygen sensor is located on the exhaust system, specifically on the rear side of the engine. It is positioned after the catalytic converter, typically on the exhaust pipe. To access it, you may need to lift the vehicle and possibly remove some components for better visibility and reach.
That code indicates a fault in the 'downstream heated O2 sensor' , bank 2.That code indicates a fault in the 'downstream heated O2 sensor' , bank 2.
You need to change the downstream sensor that is after the Catalytic Converter
Bank 2 is the drivers side of the engine Sensor 1 is before the exhaust enters the catalytic converter ( upstream )
