      I have 2004 honda accord 2.4 liter w/ “check engine” light on. I went to auto shop that had OBD code reader. code is “p0141 bank 1 sensor 2” which is O2 sensor. I checked youtube & ETCG vidds and found out there is more than one O2 sensor (upstream, downstream, pre-catalytic converter, in catalytic converter, one in the engine compartment at exhaust manifold). HELP? how do I determine which one is bad?

        yep. I’m sure you are right about suits and business protocols. I appreciate the perspective.
