Hi, I got a service engine light and rough idle with code P0131 (O2 Circuit Low Voltage Bank 1, Sensor 1) which my Haynes Repair Manual tells me is the upstream oxygen sensor. When I go to RockAuto, there are multiple brands (NTK, Bosch, Denso, Walker Products) and each has California and federal emission variants. I took the following picture of the sticker under the hood which says “U.S. EPA: For sale only in states with California emissions standards.”
I just want to confirm I should be using the California variant and what brand do you recommend?
