normally their should be one on the exhaust manifold and one under the car near the catalytic converter
It is in the exhaust either before or after the catalytic converter.
The oxygen sensors in a 2005 Chevy Malibu are in the exhaust system. You'll find them at the end of the down pipes and behind the catalytic converter.
There are two available options to replace the catalyticÊconverter. Option one, buy a universal converter that is the right size for the car. Cut the old converter from the exhaust pipes and weld on the new one. Option two, buy a direct fit converter that can be bolted in between the exhaust manifold and the exhaust pipe. No welding is needed but the direct fit converter costs more than the universal one.
All oxygen sensors are located in the exhaust system either before or after the catalytic converter.
exhaust manifold is where exhaust pipe hooks to engine!
The O2 sensors are threaded into the exhaust system, one before the catalytic converter and one after the cat.
the upstream o2 sensor is mounted in the exhaust before the catalytic converter and the downstream sensor is after the cat. conver.
Assuming that you are referring to the downstream oxygen sensor, that will be the one located after the catalytic converter (the exhaust side, not the engine side).
No.No.
Plugged catalytic converter?
it is in the exhaust system, before the muffler.
