Tahoe 1996 5.7 Vortec 5 door
Chart showing my O2 sensors are attached.
I think upstream sensors (Bank 1 Sensor 1 and Bank 2 Sensor 1) are going up and down as expected.
Downstream sensor for Bank 1 (Bank 1 Sensor 2) is also working as expected: going down the half and up again.
However, I see my downstream sensor for Bank 2 (Bank 2 Sensor 2) is stable at 0.1 volts.
I know this is a problem but I can't tell 100% if it is the O2 sensor, the catalytic converter connected to bank 2 or any gaskets/seals. ... or any combination of them.
I started the vehicle and went under it. I felt air leaking from the seal (between the pipe coming from the exhaust manifold on the engine and the catalytic converter) with my hand.
How to figure this out before buying anything?
Thanks a lot for the help.
