O2 sensors
Hi,
Does anyone know if the generic 02 sensor screwed into its bung on the CAT needs to be grounded to work properly? I mean the chassis of the 02 sensor grounded through the exhaust system that is grounded through the engine block and then to the car chassis.
Thanks!

It depends on the style of O2, if it is a single wire the body grounds it thru the system, two wires or more it my need a dedicated ground, read the instructions that comes with it.
