passenger side rear sensor --------------------------------------- actually Bank 2 is the drivers side of the engine
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
The upstream heated oxygen sensor is located ahead of the catalytic converter The downstream heated oxygen sensor is located behind the converter
Both o2 sensors are located on catalytic converter. Sensor closest to front of car is upstream sensor. Sensor closest to rr of car is downstream sensor.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
Two wire sensor on right front of intake.
For a 1997 Mercury Mountaineer ( 5.0 liter V8 ) ( there are a total of 4 oxygen sensors , 2 sensors that are used with the PCM to adjust the fuel ratio that are nearest the engine on both sides , and 2 sensors that are also called catalyst monitors because they are in the exhaust after the catalytic converters ( downstream sensors ) On the passenger side of the engine in a Mercury Mountaineer ( Bank 1 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor ) On the drivers side ( Bank 2 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor )
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The 1997 Ford F150 4.6 liter engine throttle position sensor is located on the top of the transmission. The sensor will be connected to the fuel injection rail.
This is one of the two sensors which is downstream directly after the catalytic converter.
Bank 2 is the drivers side of the engine in a Ford Expedition Sensor 2 is after the catalytic converter ( downstream )
That is located on the back top side of the catalytic converter, right where the outlet tube leads to the muffler.
