bank one is before the catalitic converter, or the front sensor ( on the front exhaust manifold)
On the exhaust pipe, from where it leaves the engine, but before the catalytic converter.
02 Sensor? should be before the cat
its before the cat around the header area
No.
Yes.
I believe there are ( 4 ) Bank 1 is the passenger side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) Bank 2 is the driver side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) The 2 sensors before the catalytic converter are used for air / fuel ratio for the engine The 2 sensors after the catalytic converter are called catalyst monitors
Two, one before and one after the catalytic converter.Two, one before and one after the catalytic converter.
bank 2 is the drivers side of the engine , and sensor 1 is near the engine before the exhaust passes through the catalytic converter , sensor 2 is after the catalytic converter
BANK # 1 is the passenger side of the engine / BANK #1 SENSOR # 1 is in the exhaust before the catalytic converter / BANK # 1 SENSOR # 2 is after the catalytic converter ( downstream ) ------------------------------------------------------------------------------------------------------------ BANK # 2 is the drivers side of the engine / BANK # 2 SENSOR # 1 is in the exhaust before the catalytic converter / BANK # 2 SENSOR # 2 is after the catalytic converter ( downstream )
The gas engine has one before the catalytic converter.
The catalytic converter is behind the engine.
There is a sensor before each converter and one after each converter.
