The 2002 GMC Envoy typically has two oxygen sensors located on the exhaust system. The upstream oxygen sensor is usually located near the exhaust manifold before the catalytic converter, while the downstream oxygen sensor is typically located after the catalytic converter.
The oxygen sensor on a 2004 Honda Accord is found on the exhaust system. They are placed close to the catalytic converter so the sensors can properly read the exhaust flow.
The oxygen sensor on a 1991 GMC Sonoma is typically located on the exhaust system, either before or after the catalytic converter. It may be found near the exhaust manifold or along the exhaust pipe. You may need to consult a repair manual or seek professional help to locate and replace it.
look on the exhaust pipe, i think it will be just after the catalytic converter ----------------------------------------------------------------------------------------------------- There is more than one. I believe all the 4cyl have 2 and the V6 has 4 I think. There will be one in the exhaust manifold and one close to the catalytic converter.
Bank 1 is the passenger side of the engine Sensor 1 is in the exhaust close to the engine before the exhaust goes through the catalytic converter Sensor 2 is after the exhaust has gone through the catalytic converter ( downstream )
On a Ford Expedition : Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 would be in the exhaust AFTER it exits the catalytic converter
Bank 1 is the passenger side of the engine in your Ford F-250 Sensor 1 is somewhere in the exhaust close to the engine , before the exhaust enters the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
Bank 2 is the drivers side of the engine on your Ford F-150 Sensor 1 is somewhere in the exhaust close to the engine before the exhaust enters the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
On a 2000 Lincoln Navigator : Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine before the exhaust enter the catalytic converter ( upstream sensor ) Sensor 2 ( downstream sensor ) would be in the exhaust after the exhaust exits the catalytic converter
On a Ford Expedition ( 4.6 and 5.4 ) Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 would be AFTER the exhaust has passed through the catalytic converter
On a 2000 Mercury Mountaineer ( 4.0 V6 and 5.0 V8 ) Bank 2 is the drivers side of the engine Sensor 1 is close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 is AFTER the exhaust has passed through the catalytic converter
